How Commerical Refrigeration Systems Work

Refrigeration suppliers will tell you there is no “one size fits all” when it comes to equipment. Not to mention, you must decide what your needs are. What will you be using it for? What capacity do you need? We have compiled a quick guide to help you out:

Commercial Upright Refrigerators are most similar to the standard home appliance. However, they are much more significant. For use in closed spaces, a covered unit such as this would suffice. But, if you’re a storefront, you may be looking for more. Thankfully, you can buy units with a glass front. This way, your customers can see what you have to offer. Additionally, this helps with stocking and proper rotation. If staff can easily see inside, it is more likely that the product will be stocked efficiently.

Merchandising Refrigerators also fall under the same category. In contrast, they are often smaller. These glass-front fridges are used as marketing tactics. Are you looking to catch the eye of customers walking by? These may be the key.

Under Counter, Fridges are also conventional. Do you know the bar/wine fridges you see in restaurants? That’s what we are talking about. They are ideal for commercial use because of the front ventilation. For this reason, they install easily in small spaces.

Another space saver is a Prep Station. In other words, a counter space combined with a fridge. These units are compact and versatile. Perfect for smaller restaurants or cafes.

You may see Walk-In Refrigeration in more extensive operations. Maybe in a restaurant? Hotel? Hospital? You name it. Walk-ins provide ample space. Plus, business owners appreciate the ability to organize. Shelving is often installed inside. Walk-in Freezers are also standard. This is your best option for overall freshness.

Commercial Refrigeration Problems and Solutions

Wishing your system would run forever? Us too. But, even the best systems need work. There are a few commercial refrigeration repairs you may be able to fix on your own. For this reason, we have compiled a few for you.

Frost or Ice Build-Up Inside Unit

If you have a buildup, something is not right. Firstly, make sure the doors are being shut properly. This is the #1 cause of ice/frost in refrigeration. Similarly, it wastes energy. In turn, creating higher costs. If this is not the issue, something else is the culprit.

Next, we suggest checking the defrost cycle. Most units have them built-in. Try increasing the cycle. That way, it will defrost more often. If these two tips don’t work, call a professional. Your coils could be freezing, or your evaporator may be malfunctioning. Either way, a visit from an HVAC technician is required.

Leaking Water

If water is leaking from an appliance, it’s never a good sign. However, it could be an easy fix. Is your space humid? With excess moisture, your unit may be working overtime. It is hard to regulate the temperature. Cue the commercial refrigeration repair call. That is to say; a humid environment is not suggested. On the other hand, it could be as simple as uneven flooring. So, don’t panic! Even a slight tilt could cause the evaporator pan to overflow. Which brings us to our last point: full evaporator pans. It may seem simple, but it is often overlooked. Add it to your list! Now!

Refrigeration Temperature

Is your fridge not cooling? Or is the temperature changing? Don’t fret just yet. Here are a few possibilities:

  • Have you set the temperature gauge?
  • Has it been 24 hours since installation? Units need a minimum of 24 hours. Let it cool before use.
  • How often do the doors open? Keep them closed when not in use. Additionally, make sure seals are intact.
  • Is your unit too full? Crowding causes efficiency to decrease. Without room for airflow, the products cannot cool.

Commercial refrigeration repairs are inevitable. But, we hope you will follow these simple steps to quick fixes.

However, for more severe issues, call a professional. Our technicians can quickly identify the problem. So, what does that mean for you? A quick solution! Don’t wait. Give us a call. We would be happy to help you today.
