8 Applications for MrCool’s New Refrigeration System
Commercial Food Refrigeration
The first thing that probably came to your mind when you thought about a walk-in refrigeration unit was commercial food. From storing products at the grocery store to chilling the prep ingredients for your favorite restaurant, the food industrial complex is wholly dependent on reliable refrigeration. Designed to support optional hardware such as a duct connection kit, an induced fan kit, and PVGo, the MrCool Compact Refrigeration System is perfect for commercial food uses. It’s never been easier to maintain the crisp temperatures you want with a single, compact refrigeration unit.
Residential Refrigeration
Not every homeowner can skirt by with only a standard indoor fridge in the kitchen. I always think of my uncle with a deep freezer full of venison in the basement and my in-laws with a soda fridge in the garage. Shoot, I had a mini fridge during college for energy drinks and snacks! Unlike a solution for a short stint of time in college dorms, though, finding the right, robust refrigeration solution for your home requires more finesse. A home walk-in may sound like a luxury, but there are many people who could benefit from one:
- Anyone who wants to decrease the frequency of their store trips
- Anyone who purchases meat in bulk (i.e., half a cow, a full pig, etc.)
- Anyone who supports local food banks and shelters by cooking and donating meals
- Anyone who likes to entertain large groups over a meal
- Anyone who deals with road flooding or other issues that cut them off from civilization
- Anyone who lives off the grid or far away from the nearest town

Outdoor Walk-In Refrigeration
Not every restaurant and grocery store has all the storage space they need inside to keep ingredients and products properly cooled. For anyone looking to get into either industry, don’t let that fact limit your real estate options. An external walk-in refrigerator is a fully viable and reliable option when you use MrCool’s Refrigeration Unit. With a design that works well in ambient outdoor temperatures ranging from 5 to 113 degrees Fahrenheit, annexing your walk-in to store ingredients in the space out back of your shop can be a simpler solution than trying to expand its square footage directly.
Pastries & Frozen Dough
If you’ve ever made a pie crust, croissant, or puff pastry, you’re in the elite class of patissiers with intimate knowledge of the benefits of cold storage for working with doughs, glazes, and all kinds of baked goods. Bakery chillers provide a chill zone of single-digit temperatures and perfect humidity to keep your butter from melting and your doughs at the perfect consistency. One of the use-case scenarios that requires the tail end of the MrCool Walk-In’s temperature regulation, you’ll have the ability to maintain the 0-to-4-degree Fahrenheit conditions you need to guarantee the perfect pastries every single time.
Meat Coolers
From trappers and hunters to anglers and other aquatic harvesters, bulk storage of meat is an overlooked but necessary application for refrigeration systems. Fresh fish sit on beds of ice at the morning market, but what’s the plan for the remainder that didn’t get sold same-day? Where will you put the full 10-point buck you bagged on your hunting trip once it’s broken down into its various cuts? A dedicated walk-in makes maintaining your meat at a temperature of 40 degrees Fahrenheit or lower an easy task.
Pro tip: Be sure to store raw meats below cooked food to avoid cross-contamination!


Vegetable Cooler
After years of trial and error, the excitement of watching your vegetable garden flourish is indescribable. But what’s your plan for those fresh veggies once they’re ready for harvesting? Sure, you could collect them up and share them with friends and family. You could even take some around the block to share with neighbors. But with food prices on the rise and regulations becoming more lax, finding a way to store the fruits of your labor is a better option. Investing in a walk-in for bulk vegetable storage gives you access to clean, delicious ingredients for any meal at a moment’s notice. No fuss, no waste, no frustration.
Florists’ Flower Storage
If you’ve ever bought flowers for a special occasion like an anniversary, Mother’s Day, or to celebrate a big promotion at work, you probably noticed the floral refrigerator at the florist. It may feel counterintuitive to see flowers in colder temperatures than the ones they require to grow and bloom, but the reasoning is sound. Properly used floral refrigerators running between 34 and 36 degrees Fahrenheit offer a multitude of benefits to any arrangements and cut flowers stored inside, including:
- Slowing the aging process for cut flowers through water loss minimization
- Preventing wilting, decay, and discoloration from temperature fluctuations
- Conserving the smell and freshness of cut flowers by limiting their exposure to the elements
- Creating an environment that’s inhospitable to bacterial growth


Medicine & Vaccine Storage
For those who don’t work in the medical field, it may surprise you to learn that some medicines, particularly vaccines, need to be stored at cooler temperatures. You see this in practice in places other than pharmacies and the doctor’s office! In fact, many of the vets I’ve taken my pets to over the years have had dedicated medication refrigerators. The CDC (Centers for Disease Control) states that vaccines must be stored in temperatures between 36 and 46 degrees, the ideal conditions hitting near the middle of the range at a crisp 40 degrees Fahrenheit. It’s not just vaccines; medications like insulin, eye drops, some migraine scripts, and more require refrigerated storage to keep their potency and avoid breaking down.
Keep Your Product (Mr)Cool with IWAE
For many industries, reliable refrigeration isn’t just nice to have; it’s one of the most basic needs. No restaurant would be able to make it without a working walk-in. Florists would never be able to hold onto good-quality flowers long enough to sell them in conditions that weren’t stable and chilly. Long-term storage of vaccines, ingredients, foods, and more is what allows these industries to not just survive, but thrive and grow.
The MrCool Compact Refrigeration Unit doesn’t just promise cool performance. MrCool put their money where their mouth is by making sure the walk-in earned UL listing, CSA listing, and ETL listing. MrCool then backed their refrigeration unit with a warranty that includes 3 years of coverage on the compressor and 1 year on parts, as well as a 1-year unit replacement warranty. This powerful combination of proven performance proves that you don’t have to worry about the MrCool Compact Refrigeration Unit’s safety and longevity.
