Closed Commercial Freezer: What You Need to Know

Not only do you have to consider which type of display refrigeration is the most energy efficient, but also that commercial refrigeration will help increase sales. You also need a commercial refrigerator that is customer-friendly and food-safe.

energy efficiency

This is a very important consideration because energy efficiency directly affects your bottom line. The more display refrigerators you need, the more energy they consume. This may increase your energy bills. So, which is more energy efficient when it comes to showing cooling?

At first glance, you might think that an open display case is less energy efficient. Still, there are a few things to consider. First, open-display refrigerators are designed to help control cold air. There's no denying, however, that there's a palpable chill in the air as you walk down the aisles of the grocery store with its open display cases. The busier the area, the more energy is lost, which can affect refrigerator temperatures and food quality.

Customer convenience

Open-door display refrigerators are indeed more convenient for customers; they can grab and go. On the downside, however, this easy access also makes your cold storage aisle very uncomfortable for customers with cold air. In winter, it's not so obvious because people dress warmly. However, shopping in the refrigerated aisle can be very uncomfortable during the summer months when people are wearing light clothes and the air conditioner is blowing them.

This can make customers feel the need to leave quickly, so they miss out on browsing the available options. Not only is it bad for them, but it's also bad for sales too. Also, as mentioned above, if you opt for easy-to-use sliding doors or display refrigerators with self-closing doors, it’s not difficult for customers to just open the door to get their food or drink.


Closed display refrigerators can be placed anywhere, while open-display refrigerators cannot. If an open display refrigerator is exposed to external drafts and air currents, it can cause malfunctions. So, for example, if you want the display case to be at the front of the store, this can be a problem with an open display case. This is especially dangerous during the summer months when warm air enters the store and affects performance.
Other risks of drafts include air conditioning, windows, and fans, which can negatively affect the performance of open display cases. The more airflow and temperature changes in the area, the harder it will be for an open-display refrigerator to maintain the ideal temperature.
