If you’ve ever walked into a grocery store, grabbed a cold soda from a convenience store cooler, or picked up fresh produce from a restaurant’s prep area, you’ve been surrounded by commercial refrigeration equipment. As someone who’s been in the commercial refrigeration supply game for over a decade now, I can tell you there’s way more to these units than just “big boxes that keep things cold.” Each type serves a specific purpose, and picking the wrong one for your space can lead to wasted energy, spoiled product, or even compliance headaches. Let’s break down the main types I supply, how they work, and when you’d need each one. Commercial Refrigeration Equipment
First up, display cases—probably the ones you’re most familiar with, even if you don’t know their official names. I split these into two big categories: reach-in display cases and open air display cases. Reach-in models are the ones with glass doors, right? You’ve seen them in convenience stores, holding milk, yogurt, or pre-packaged sandwiches. They’re insulated, so they don’t lose cold air every time someone opens the door, which makes them energy-efficient for high-traffic spots. A lot of my restaurant clients use these for back-of-house too, to store ingredients that need to be visible but kept cold. The other display type is open air, no doors at all—think of the soda coolers at gas stations, or the fresh meat cases in a supermarket. These are designed for impulse buys, but they need constant airflow to keep the temperature steady, so they use a bit more energy. I always tell clients to install them away from heating vents or direct sunlight, because that extra heat makes the compressor work way harder than it has to.
Next, reach-in refrigerators and freezers—these are the workhorses of kitchens, but not the same as display cases. Wait, why’s that? Display cases are built for customer-facing appeal, so their shelves are spaced to show off product, but reach-ins are built for storage capacity. A typical 36-inch reach-in fridge can hold twice as much as a similar-sized display case, because there’s no fancy glass front getting in the way of interior space. They come in single or double doors, some with split sections for fridge and freezer in one unit—super handy for small cafes that don’t have room for two separate stands. I also supply compact reach-ins for offices or small coffee shops, but for big restaurants, I sell the modular ones that you can link together to create a whole bank of storage. Freezer reach-ins work the same way, just set to lower temps, so they hold frozen meals, ice cream, or raw meat that needs to stay below 0°F. One thing I warn clients about: don’t overload them. If you block the air vents inside, the compressor will run nonstop, which drives up utility bills and shortens the unit’s life.
Then there’s walk-in coolers and freezers—these are the big ones, the ones that make a restaurant’s cold storage possible when they need to stock a week’s worth of ingredients instead of just a day’s. Walk-ins are customizable, right? You can get them in different sizes, from 5×8 for a small deli to 20×30 for a full-service restaurant. I supply two main types: modular walk-ins, which come in pre-made panels you assemble on-site, and custom-built ones, where we design every part to fit your exact space, even if it’s an odd-shaped corner. Modular is cheaper and faster to install, which is perfect for new businesses, while custom is great for existing spots where you can’t rearrange walls. Walk-in freezers are way more expensive to operate than coolers, because they have to work harder to maintain that deep freeze. A lot of clients don’t realize that—they just assume it’s like a big fridge, but no, I always remind them to insulate the floors too, because cold air sinks. I’ve had clients skip that and end up with frozen ground around the walk-in, which is a mess to fix.
Another type I get asked about a lot is undercounter refrigeration. These are units that fit right under a countertop, so they don’t take up extra floor space. Bars and coffee shops love them for storing beer, wine, or espresso shots within easy reach. They come in both fridge and freezer versions, some with drawers instead of doors for easier access to small items. I also supply blast chillers, which are a specific kind of undercounter (or sometimes standalone) unit that’s not just for cold storage. Wait, what’s a blast chiller? It’s used to rapidly cool hot food—like if a restaurant makes a big batch of soup at the end of the night, they have to cool it from 140°F to 40°F in 2 hours or less, per food safety rules. Blast chillers do that by blowing super cold air at high speed, which prevents bacteria from growing. A lot of my catering clients swear by these, because they let them prepare food in advance without risking spoilage. I also do blast freezers, which go even lower, for freezing ice cream, desserts, or even seafood quickly.
Wait, let’s not overlook commercial-grade ice machines and storage bins. Ice is a huge part of any food service business—restaurants, bars, hotels all go through tons of it. The ice machines themselves are usually mounted on top of storage bins, or under counters, depending on space. I sell two main types: cube ice, which is the standard for drinks, and flake ice, which is used for displaying fresh seafood or keeping food cold for catering. Storage bins are insulated, so they keep ice from melting, and some even have built-in scales to measure how much ice you’re using. I always tell clients to get a bin that’s a bit bigger than they think they need, because nothing’s worse than running out of ice during a busy weekend shift. Also, you have to clean these machines regularly—mineral buildup can affect ice quality and make the unit work harder. That’s a tip I give every time I install one.
Then there’s remote vs. self-contained units, which is a distinction that matters a lot when choosing what to buy. Self-contained units have the compressor built right into the unit itself—they’re easier to install, because you just plug them in and go. That’s great for small businesses or temporary setups, like a pop-up shop. But if you’re installing a big walk-in cooler or a bank of display cases, remote units are better. The compressor is outside, usually on the roof or a separate utility pad, which means less noise in your space and more efficient cooling. I usually recommend remote units for anything over 10 cubic feet, because they save money on energy in the long run. But it’s not a one-size-fits-all—if you have a small café with limited outdoor space, a self-contained undercounter is probably the way to go.
I should also mention energy efficiency, because that’s a big concern for most of my clients these days. A lot of states have regulations for commercial refrigeration, especially around new units—you can’t just buy any old fridge anymore, it has to meet certain SEER ratings or energy standards. I only stock units that are ENERGY STAR certified, because they use up to 15% less energy than standard models, which adds up to hundreds of dollars a year in utility bills. Also, regular maintenance is key—even the best unit will break down if you don’t clean the coils or check the refrigerant levels. I offer a maintenance package for all my clients, because I know how stressful it is when a fridge breaks down in the middle of a busy shift.
Wait, what about niche types? Like beer keg coolers, right? Those are standalone units or undercounter units designed to hold whole kegs, so bars don’t have to store kegs in a walk-in. They keep the beer at the perfect serving temperature, which is usually around 38°F. I also sell wine coolers, which are different from regular reach-ins—they’re calibrated to keep wine at a consistent 55°F, with low humidity to keep corks from drying out. Restaurants with wine lists, or even small wine shops, love these for storing their selections. And then there’s deli cases, which are a type of display case with a curved glass front, designed for slicing cold cuts, cheese, and salads. They’re not just for showing product—they’re built to keep deli items at a safe temperature, and some have built-in slicing surfaces on top, which is super convenient.
I’ve been doing this long enough that I’ve seen clients make the same mistakes over and over. Like, someone runs a small café and buys a huge walk-in cooler because they think they’ll need it one day, but it costs them extra every month in energy, and half the space goes unused. Or another client buys a cheap display case for their convenience store, and it breaks every six months, costing them more in repairs than a higher-quality unit would have. That’s why I always take the time to ask clients about their space, how much traffic they get, what products they store, and their budget before suggesting anything. I don’t just push the most expensive unit— I find the one that works best for their specific needs.
If you’re a new business owner setting up your kitchen, or an existing one looking to upgrade or replace old equipment, don’t just guess what you need. A lot of people don’t realize that commercial refrigeration isn’t like the fridge in their home. Home fridges are made for a family of four, with low usage, while commercial units run 24/7, 365 days a year. The build is tougher, the insulation is better, and they’re designed to handle heavy use. Buying a residential fridge for a restaurant is a recipe for disaster—it’ll break down in months, and it’s not food-safe for commercial use.
I also want to touch on food safety, because that’s non-negotiable. The FDA requires that commercial cold storage keep food at 40°F or below, and freezers at 0°F or below. All the units I supply are tested to meet those standards, but you have to use them correctly. Don’t put hot food straight into a fridge—let it cool down to room temp first, because that will raise the temperature inside and make other food unsafe. And make sure your thermometers are working—every unit should have a built-in thermometer, and you should check it daily to make sure it’s accurate.
Commercial Dishwashers At the end of the day, commercial refrigeration is the backbone of any food service or retail business that sells perishable products. Without the right equipment, you’ll lose money to spoiled food, deal with unnecessary repairs, and even risk health code violations. If you’re not sure what type you need, or you have questions about sizing, energy efficiency, or maintenance, hit me up. I can walk you through your options, answer any questions you have, and make sure you get the right equipment for your space and budget. Don’t wait until your old fridge dies and you’re scrambling to replace it—reach out now, and we can get set up before the busy season hits.
