Key Differences Between a Temporary Walk-In Cooler and a Built-In Walk-In

The most striking difference is speed. While permanent coolers involve weeks of construction, permits, and headaches, a temporary walk-in cooler can be up and running in as little as 5 minutes for folding models. Even the larger trailer-mounted units typically take less than 30 minutes to set up. As one of our clients put it, "It's like having a refrigerator genie that grants your cold storage wishes!"

Mobility is another game-changer. Temporary units are designed to follow you wherever your business takes you. Many feature built-in wheels, trailer hitches, or collapsible designs that make transportation a breeze. Meanwhile, once a permanent walk-in is installed, it's staying put unless you're ready for a major demolition project.

From a financial standpoint, temporary coolers offer flexibility that permanent installations simply can't match. Rentals allow you to scale cold storage up or down based on your needs, paying only when necessary. No more maintaining an oversized cooler year-round just for those few peak weeks!

The paperwork burden is also dramatically different. Most temporary walk-in coolers don't require building permits since they're not permanent structures. You might still need health department approval for food service, but you'll avoid the complex building code compliance issues that come with permanent installations.

When Do You Need a Temporary Walk-In Cooler?

Special events are where temporary coolers truly shine. Whether you're catering a wedding for 300 guests, running a weekend food festival, or organizing a corporate retreat, having refrigeration right at the venue eliminates stressful shuttling of perishables back and forth from an off-site kitchen.

When disaster strikes, these units become essential infrastructure. After hurricanes, floods, or power outages, temporary walk-in coolers preserve critical supplies like medications, vaccines, and food. Their ability to run on generators makes them heroes during emergency situations when the power grid fails.

Restaurant renovations or equipment failures can spell disaster without a backup plan. When a permanent cooler breaks down unexpectedly, a temporary unit can arrive within hours. As one relieved restaurant owner told us, "That temporary cooler Icebox delivered at midnight saved us from losing our entire weekend inventory when our main system died Thursday evening."

Seasonal harvests create sudden refrigeration demands that permanent solutions can't always handle. Farmers love placing our temporary coolers directly at their fields, cooling produce immediately after harvest to extend shelf life and maintain quality. The units' mobility means they can follow the harvest from field to field as needed.

The market offers several distinct types of temporary walk-in coolers, each designed to address specific short-term refrigeration needs. Understanding the options available helps you select the right solution for your particular situation.

Portable Folding Walk-Ins (4'×4' to 8'×20')

Picture this: you unfold what looks like a large box, and within five minutes, you have a fully functional walk-in cooler. That's the magic of portable folding walk-ins! These innovative units collapse down to just 30 inches high and weigh around 300 pounds, making them easy to transport in the back of a standard pickup truck.

The fold-and-roll design means a single person can move and position these units thanks to their pre-installed casters. Just unfold, lock the panels in place, plug it in, and you're ready to chill.

"I set one up outside my food truck to keep a weekend's worth of product cold without having to buzz back and forth to my shop," shares one vendor. "It was a game-changer for festival service."

What makes these units especially practical is their modest power needs. Most operate on standard 115V power, drawing less than 10 amps – just plug into a common wall outlet or small generator. Despite their compact footprint, they pack impressive capacity. A standard 4'×4'×6'6" model offers 105 cubic feet of storage space and can support up to 1,000 pounds of product – that's a lot of beverages for your next event!

Trailer-Mounted Coolers & Freezers

When you need cold storage that follows you anywhere, trailer-mounted temporary walk-in coolers are the way to go. These units come ready to hit the road – just hook them to your vehicle and you've got commercial-grade refrigeration wherever your travels take you.

From compact 5'×10' models holding 283 cubic feet (or 6,400 pounds) of goods to spacious 20'×8' units offering approximately 880 cubic feet of storage, there's a size for every need. Temperature flexibility is impressive too – these units maintain anything from comfortable refrigeration at 42°F down to proper freezing at -10°F.

Most trailer-mounted coolers run on all-electric systems, eliminating the noise and fumes you'd get with diesel alternatives. "Our versatile all-electric mobile cold storage trailers are the safest and most convenient cost-effective solution for temporary refrigeration or freezer needs," notes an industry expert. Running on standard 110V and 15 amps, they'll work with most household outlets, and generator options are available for remote locations.

The applications seem endless – restaurants needing backup during repairs, caterers serving off-site events, florists during Valentine's Day rush, farmers market vendors, breweries hosting festivals, and emergency response teams. Best of all, in a crisis, these units can often be delivered within 4 hours and ready for loading just 30 minutes later.

Collapsible Hunting & Ranch Coolers

For those who need refrigeration where the pavement ends, collapsible hunting and ranch coolers provide a clever solution. These specialized temporary walk-in coolers combine pop-up tent technology with innovative cooling systems to create field-ready meat storage that goes where permanent coolers simply can't.

Systems like the MEATLOCKER use an insulated foldable enclosure with an A/C duct and CoolBot controller to transform a standard window air conditioner into an effective game cooler. Even when the outdoor temperature hits 80°F, these units maintain mid-30s°F inside – perfect for properly aging your harvest.

The features are custom to hunters' needs, with folding meat pole systems capable of supporting over 440 pounds of hanging game. "Why build a permanent walk-in cooler building when this costs thousands less, sets up in minutes, and stores out of the way when not in use?" one manufacturer asks. It's a fair question, especially considering these systems can double as summer patio cooling stations in the off-season.

Setup couldn't be simpler. Most pop-up enclosures deploy in 5-10 minutes, requiring only a compatible 12,000+ BTU window air conditioner and a CoolBot controller. This simplicity makes them perfect for remote hunting camps where construction would be impractical or impossible.

"Splitting the cost with my hunting buddies made this a no-brainer compared to building a permanent cooler we'd only use a few weeks a year," explains one satisfied hunter. For ranchers, game processors, and outfitters, these specialized solutions provide cost-effective cooling that can be shared among multiple users.

Key Features, Accessories & Outdoor Considerations

When shopping for a temporary walk-in cooler, the details really do make all the difference. Just like buying a car, it's not just about getting from point A to B—it's about finding the features that make your life easier. From insulation quality to the right accessories, these elements ensure your cooler performs exactly as needed, whether you're storing wedding cake or field-dressed venison.

The insulation R-value in these units is impressive—typically R-25 to R-32—keeping your products cold while minimizing energy use. Most temporary coolers offer a choice between standard 110V operation (perfect for household outlets) and 220V connections for larger units or lower amperage draw. Digital thermostats have become standard, allowing you to dial in the exact temperature your products need.

If you're placing your cooler outdoors, look for models with weatherproof roofing and UV-resistant panels. These features ensure your unit stands up to whatever Mother Nature throws at it, from summer thunderstorms to winter snow.

Must-Have Accessories for a Temporary Walk-In Cooler

shelving and strip curtain kit for walk in cooler - temporary walk in cooler

The right accessories can transform your basic cold box into a highly efficient storage solution. LED lighting systems are a game-changer—they provide bright, energy-efficient illumination without generating heat (the last thing you want in a cooler). Plus, they're easier on the eyes when you're searching for that one specific container at 2 AM.

"The LED lights in our rental unit made all the difference during our nighttime wedding reception," shares one Icebox customer. "We could quickly find what we needed without leaving the door open too long."

Temperature loggers have become essential, especially if you're storing food that needs to meet health department requirements. These small devices track and record temperature data, providing documentation that can save you during an inspection. Some newer models even send alerts to your phone if temperatures drift outside safe ranges—talk about peace of mind!

Door alarms might seem like overkill until you've experienced staff leaving doors ajar during a busy event. These simple devices alert you when doors remain open too long, preventing temperature abuse and saving on electricity costs.

Wire shelving systems maximize your usable space and promote better air circulation around products. Most standard temporary walk-in coolers can accommodate two shelving units with four tiers each, dramatically increasing your storage capacity without taking up more floor space.

Strip curtains are the unsung heroes of walk-in efficiency. These clear plastic strips hang inside the doorway, creating a barrier against warm air while allowing easy access. They're particularly valuable during high-traffic periods or in hot environments where every cold air molecule counts.

For meat processing applications, meat rail systems are essential. These overhead rails support hanging products, improving air circulation and freeing up valuable floor space. Most folding systems can support over 440 pounds of product—plenty for even the most successful hunting trip.

Getting products in and out easily is crucial, which is why external ramps are so valuable, especially for units with raised floors. If you'll be using hand trucks or carts, this accessory quickly pays for itself in convenience and safety.

Weatherproofing for Outdoor Use

Setting up your temporary walk-in cooler outdoors introduces a whole new set of considerations. Proper weatherproofing isn't just about protecting your investment—it's about ensuring consistent performance regardless of what's happening outside.

Quality door gaskets are your first line of defense against the elements. Look for magnetic seal gaskets that maintain consistent pressure around the entire door perimeter, creating a watertight seal that keeps rain out and cold air in. When inspecting a unit, check that the gaskets are pliable and make full contact when the door is closed.

"We had our Icebox cooler out during a three-day festival that included a tropical downpour," recalls an event coordinator from Virginia Beach. "The gaskets held tight—not a drop inside the unit, and our temperatures never fluctuated."

A rain fly or membrane roof cap provides additional protection against downpours. These overlays direct water away from the cooler's roof panels and prevent leaks at seam points. Some higher-end models include these as standard features, but they're worth adding if you'll be in a rainy climate.

Skid mounts might not seem exciting, but they're crucial for outdoor installations. By elevating your cooler above ground level, they protect against flooding, mud, and ground moisture. This elevation also improves air circulation beneath the unit, preventing condensation and potential mold issues.

The sun can be just as challenging as rain, which is why UV-resistant panels are important for extended outdoor deployment. Standard galvalume finishes offer decent protection, but specialized UV-resistant coatings extend panel life and maintain insulating properties during long-term outdoor use.

Don't forget about the heart of your cooling system—the condensing unit needs protection too. Weather hoods or covers shield vital refrigeration components from direct exposure to rain, snow, and debris without impeding the airflow necessary for efficient operation.

When setting up on uneven terrain (like many outdoor event spaces), leveling systems ensure proper operation. Most trailer-mounted units include adjustable jacks for leveling, a critical step that prevents door alignment issues and ensures proper refrigerant flow.

Finally, outdoor-rated electrical components provide protection against moisture-related electrical failures. GFCI protection, weatherproof outlets, and sealed electrical connections are essential safety features for outdoor operation.

At Icebox, all our outdoor-rated temporary walk-in coolers include comprehensive weatherproofing features. We've designed our units to withstand everything from Florida's summer humidity to Pennsylvania's winter snowfall, ensuring your products stay perfectly chilled regardless of the forecast.

Setup, Power Requirements & Food Safety Best Practices

Setting up a temporary walk-in cooler is remarkably straightforward, but understanding the power requirements and food safety considerations ensures you'll get the most from your portable cold storage solution.

walk in cooler setup process - temporary walk in cooler

Most portable folding units transform from compact travel mode to fully operational in just five minutes. The process couldn't be simpler - position your collapsed unit, unfold the pre-hinged panels, secure everything with the built-in latches, plug it in, and set your desired temperature. It's cold storage without the headache of complicated assembly.

Trailer-mounted units arrive practically ready to use. Just position the trailer where you need it, level it using the built-in jacks, and connect to power. Our delivery team handles the setup and verifies everything is working perfectly before leaving you to enjoy your instant cold storage solution.

When it comes to power, most temporary walk-in coolers are designed with convenience in mind. Our smaller portable folding coolers run happily on standard 115V/120V household outlets drawing just 10-15 amps - about the same as a coffee maker. Standard trailer coolers typically need 120V at 20 amps, while freezer units require 220V with 30 amps and special L14-30 twist-lock connections. For those ultra-cold applications, we offer units that connect to 220V with 6-20P connections.

"The best part about our units is that most just plug into a standard outlet - no electrician required," shares one of our regular customers who uses our coolers for weekend farmers markets.

No power outlet nearby? No problem! We can provide generator options sized perfectly for your needs. Just remember to add about 50% to the running wattage to account for startup surge. For example, if your cooler draws 1,800 watts (15 amps at 120V), you'll want a generator rated for at least 2,700 watts to handle that initial power spike when the compressor kicks on.

Food safety compliance isn't optional when you're storing perishables, which is why all our temporary walk-in coolers are NSF-approved for food storage. They meet the same rigorous standards as permanent installations, giving you peace of mind when health inspectors come calling.

To keep everything by the book, maintain refrigerated items between 36°F and 40°F, and keep freezers at 0°F or below. We strongly recommend using temperature logging devices to document your consistent temperature control - these records are gold during inspections. Don't forget to implement a regular cleaning schedule and follow proper HACCP guidelines for food storage, including appropriate product separation and rotation.

Powering Your Temporary Walk-In Cooler Safely

Safe electrical connections are absolutely crucial when setting up a temporary walk-in cooler. The last thing you want is an electrical issue interrupting your cooling when you're storing thousands of dollars worth of product.

GFCI protection is non-negotiable, especially for outdoor installations. These clever devices detect current imbalances and automatically shut off power to prevent electric shock - think of them as your invisible electrical safety guard. When using an extension cord or generator, make sure this protection is in place.

When it comes to extension cords, not just any cord will do. Use only heavy-duty, outdoor-rated cords (12-gauge minimum) and keep them under 50 feet to prevent voltage drop. Always check that your cord's amperage rating exceeds what your cooler needs, and protect those cords from foot traffic, vehicles, and water exposure. As our operations manager likes to say, "The right extension cord is the difference between reliable cooling and a tripped breaker at the worst possible moment."

Surge protection is your cooler's best friend, especially when running from generators or in areas with unstable power. These devices shield sensitive electronic components from power fluctuations that could otherwise cause expensive damage.

Whenever possible, give your temporary walk-in cooler its own dedicated circuit. This prevents overloads and tripped breakers when other devices cycle on. For our 220V units, a dedicated 30-amp circuit is typically required for proper operation.

Proper grounding ensures electrical safety throughout the system. Before connecting your cooler, verify that all outlets are properly grounded. If you're using a generator, follow the manufacturer's grounding instructions carefully - this isn't the place to take shortcuts.

At Icebox, we include properly sized power cords and clear connection instructions with every unit. Our delivery teams always verify proper electrical setup before leaving your site, ensuring safe and reliable operation from the moment we drive away.

Maintaining Safe Temperatures and Sanitation

Keeping your temporary walk-in cooler at the right temperature isn't just about compliance - it's about protecting your valuable inventory and your customers' health.

The FDA Food Code specifies that refrigerated foods must stay at 41°F or below, but we recommend maintaining temperatures between 36°F and 40°F. This "safety buffer" accounts for door openings and temperature fluctuations that happen during normal use.

Data loggers are worth their weight in gold for temperature monitoring and documentation. These devices silently record temperatures at regular intervals, creating a clear record for health inspections. Many of our customers love the modern loggers with smartphone connectivity that allow them to check temperatures remotely and receive instant alerts if anything drifts out of range.

While the ambient air temperature is important, don't forget to verify internal product temperatures with a digital thermometer. This helps identify any cold or hot spots that might affect food safety. One of our catering clients finded a corner of their cooler was running warmer than expected, allowing them to adjust product placement before any issues occurred.

Daily temperature logs show your commitment to consistent temperature control. We recommend assigning staff to check and record temperatures at least twice daily, noting any fluctuations or corrective actions taken. These records aren't just for inspectors - they help you spot patterns and prevent problems before they start.

When it comes to keeping your temporary walk-in cooler clean, a simple daily wipe-down with food-grade sanitizer goes a long way. Clean up spills immediately to prevent cross-contamination, and schedule a weekly deep cleaning of shelving and floor surfaces. Don't forget those door gaskets and strip curtains - they need regular inspection and cleaning to maintain proper sealing.

"Proper sanitation extends beyond food safety—it also improves cooling efficiency and extends the life of your equipment," notes our service manager. "Clean condenser coils and proper air circulation are essential for optimal performance."

For units with aluminum or stainless steel interiors, avoid harsh chemicals that might cause corrosion. Instead, use mild detergents and food-grade sanitizers specifically formulated for food service environments.

At Icebox, we provide comprehensive sanitation guidelines with all our rental units. Our team can also recommend appropriate cleaning products and protocols custom to your specific application and local health department requirements. When you rent from us, you're never on your own when it comes to maintaining safe and sanitary conditions.

Rent vs Buy: Cost Breakdown & Decision Guide

When considering a temporary walk-in cooler, one of the most important decisions is whether to rent or buy. Each option offers distinct advantages depending on your specific needs, timeframe, and budget.

Pros and Cons of Renting a Temporary Walk-In Cooler

Renting a temporary walk-in cooler makes perfect sense for many businesses, especially those with short-term or occasional needs. The financial appeal is immediate – instead of investing thousands upfront, you'll typically pay between $100-300 per day, with significant discounts available for weekly and monthly rentals.

"Having 24/7 service support included in our rental gave us peace of mind during our three-day outdoor festival," shared one event planner who appreciated the worry-free experience of renting.

The flexibility of rental options is another major advantage. Need a small unit for a weekend wedding? No problem. Need to scale up for holiday production? Just make a call. Rental providers like Icebox offer various sizes and temperature ranges to match your exact requirements.

Perhaps the most underrated benefit is having service and maintenance included in your rental fee. When something goes wrong with refrigeration equipment (and eventually, something always does), a simple call brings technicians to your site, often within hours. No unexpected repair bills, no hunting for specialized technicians.

Between uses, you won't need to worry about storage space – a significant consideration for seasonal businesses with limited facilities. And you'll always have access to the latest technology without committing to a specific model that might become outdated.

For emergencies, the value of immediate availability cannot be overstated. Icebox offers 24-hour emergency delivery throughout our East Coast service area, with units often arriving within 4 hours of your call – crucial when your primary cooler fails unexpectedly.

Of course, renting isn't perfect for everyone. The long-term cost will exceed ownership if your needs are consistent and frequent. You'll also face some limitations on customization compared to owning your unit. And during peak seasons like summer weddings or holiday periods, availability constraints might become an issue without advance reservation.

For businesses with seasonal needs, special events, or emergency situations, renting typically provides the most cost-effective solution. For more information about our rental options, visit our Rentals page.

Pros and Cons of Buying a Temporary Walk-In Cooler

Purchasing a temporary walk-in cooler makes financial sense for businesses with regular, predictable cold storage needs. While the initial investment ranges from $4,000 for small portable units to $40,000 for large trailer-mounted systems, ownership offers compelling long-term advantages.

Asset ownership builds your business's equipment portfolio with something tangible that maintains value. A quality temporary cooler can last 10-15 years with proper maintenance, steadily decreasing your cost per use over time. With regular use, the daily cost quickly drops well below rental rates.

"I evaluated several options and found that the CoolBot Walk-in Cooler was the perfect solution for my small brewery business – it's affordable, easy to assemble, and easy to use. Best of all, it works perfectly!" shares a business owner who chose to purchase rather than rent.

The freedom of complete customization allows you to tailor the unit exactly to your needs. Want specialized shelving configurations? Need custom meat rail setups? Ownership lets you modify your cooler in ways rental units simply can't accommodate.

Having immediate availability whenever needed eliminates dependency on rental inventory, which is particularly valuable during high-demand seasons when rental units might be scarce. Some entrepreneurial owners even generate additional revenue by sub-renting their units to other businesses during periods when they don't need them.

Ownership also brings potential tax benefits including depreciation deductions and possible eligibility for Section 179 expensing (though you should always consult your tax professional for specific advice relevant to your situation).

But ownership isn't without drawbacks. The high initial investment requires significant capital that could be used elsewhere in your business. You'll also take on full maintenance responsibility – regular service, repairs, and compliance updates become your obligation rather than the rental company's problem.

You'll need adequate storage space between uses, which presents logistical challenges for many businesses. And there's always the risk of technology obsolescence as newer, more efficient models enter the market while you're still paying off your purchase.

At Icebox, we understand this isn't a one-size-fits-all decision. That's why we offer both rental and purchase options, allowing you to choose the solution that best fits your specific situation. Our team can even help you run the numbers based on your anticipated usage to determine which option makes the most financial sense for your unique needs.

Frequently Asked Questions about Temporary Walk-In Coolers

Do temporary walk-in coolers run on standard household power?

Yes, most temporary walk-in coolers are designed with convenience in mind, running perfectly fine on the power you already have in your home or business. The beauty of these units is their simplicity – small to medium-sized coolers typically operate on standard 110V/115V outlets drawing just 10-15 amps, the same as many household appliances.

This plug-and-play design means you can set up professional-grade refrigeration without calling an electrician or rewiring your space. For standard refrigeration units keeping food at that ideal 36°F to 40°F range, a regular 15-amp circuit handles the job beautifully.

A restaurant owner in Charleston told us recently, "We were honestly shocked at how easy it was. We thought we'd need special wiring, but our temporary cooler just plugged into the wall outlet behind our prep station. Five minutes later, we had extra cold storage right when we needed it most!"

If you're looking at freezer units or larger coolers, you might need a bit more juice – typically a 20-amp circuit or 220V power. But even then, many buildings already have these outlets available for appliances like dryers or ovens.

Don't have accessible power at your location? No problem. Generator options work wonderfully with these units. Just remember the golden rule of generator sizing: go about 50% larger than your unit's running wattage to handle that initial startup surge. For instance, if your cooler draws 15 amps at 120V (about 1,800 watts), look for a generator rated at least 2,700 watts.

At Icebox, we make sure every rental comes with clear power specifications and the right plugs. Our delivery teams are happy to check your power situation and confirm everything's compatible before we leave you with your new cooling solution.

How fast can a unit be delivered and operational?

When you need cold storage in a hurry, timing is everything. That's why at Icebox, we've streamlined our delivery process to get you up and running as quickly as possible, especially in emergencies.

For urgent situations, our 24/7 emergency service throughout the East Coast can have a temporary walk-in cooler arriving at your doorstep within just 4 hours of your call. We understand that when refrigeration fails, every minute counts.

The journey from your initial call to a fully operational cooler typically follows this timeline:

  1. We'll assess your needs in a quick 15-30 minute conversation
  2. Our team schedules delivery and dispatches your unit (30 minutes to 4 hours, depending on urgency)
  3. Transportation to your location takes 1-3 hours based on distance
  4. On-site setup and testing takes about 30 minutes
  5. The unit needs 1-2 hours to cool down to your target temperature

For our trailer-mounted units, we can often complete the entire process – from your initial call to having a fully operational cooler at your site – in as little as 4.5 hours. Our portable folding units can be even quicker since they're more compact to transport.

A catering manager in Virginia Beach shared, "When our refrigeration went down the morning of a 300-person wedding, I thought we were doomed. Icebox had a replacement unit on-site and cooling down before our prep team even finished their lunch break. They literally saved the event!"

For non-emergency situations, we recommend giving us 24-48 hours' notice when possible. This extra time allows for proper site preparation and ensures we have the perfect unit available for your specific needs.

Can I build a DIY temporary walk-in cooler with a CoolBot?

Absolutely! Building your own DIY temporary walk-in cooler using a CoolBot controller and a standard window air conditioner is definitely doable if you're comfortable with basic construction and have a bit of DIY spirit.

The CoolBot system is quite clever – it essentially tricks a regular window air conditioner into thinking it's warmer than it actually is, causing it to cool spaces down to refrigeration temperatures (typically 36°F to 40°F). It does this by placing a small heater right next to the AC unit's temperature sensor, making the air conditioner work harder and longer than its original design intended.

To create your own setup, you'll need:

  1. An insulated enclosure (either build one from foam panels or convert an existing small room)
  2. A compatible window air conditioner (12,000+ BTU recommended)
  3. A CoolBot controller
  4. Basic tools and electrical supplies

Cost-wise, DIY solutions typically run between $1,500 and $4,000 depending on size and materials. That's significantly less than commercial units, which range from $4,000 to $40,000.

A small farm owner from North Carolina told us, "Our DIY CoolBot cooler has been a game-changer for our CSA program. We built it for about $2,000 using insulated panels, and it's paid for itself in the first season by extending our produce shelf life."

While these homemade solutions can work wonderfully for many applications, they do come with some trade-offs to consider:

Durability might not match commercial-grade equipment, especially in demanding environments. Temperature control tends to be slightly less precise than professional units. Most DIY coolers aren't certified for commercial food service, which could be an issue if you need health department approvals. And when problems arise, troubleshooting and repairs fall entirely on your shoulders.

For businesses requiring certified food storage or consistent commercial-grade performance, professionally manufactured temporary walk-in coolers typically provide better reliability and compliance. But for seasonal use, hunting camps, or small farm operations, the DIY route can be a perfect fit.

They come in various formats to suit your specific needs—from ultra-portable folding units that set up in minutes to road-ready trailer systems that can handle massive inventory volumes. Each style has its sweet spot, whether you're cooling flowers for a special event or preserving game meat during hunting season.

Most units are designed with convenience in mind, running on standard household power (110V/115V). This true plug-and-play approach means no electrician required—just connect to a standard outlet and you're cooling within minutes.

The speed of deployment is truly remarkable. Folding models can be operational in just 5 minutes, while even the largest trailer-mounted systems typically take less than 30 minutes to set up. No construction crews, no permits, no waiting.

Temperature flexibility meets virtually any refrigeration need, from the standard 36°F to 40°F range for fresh foods to freezer models capable of reaching -10°F for ice cream and frozen meats.

"We feel like proud new parents of our cooler," one customer told us after finding how a temporary walk-in cooler transformed their business operations. That kind of satisfaction comes from finding the perfect solution to what seemed like an impossible challenge.

The rental versus purchase decision ultimately depends on your specific situation—rental provides flexibility and eliminates maintenance concerns, while purchasing makes more financial sense for frequent or long-term users.
