What to Do When Ice Forms in Your Commercial Freezer July 8, 2019

What to Do When Ice Forms in Your Commercial Freezer, La Crosse, Wisconsin

If you’ve noticed major ice buildup in your commercial freezer, it’s time to take action immediately. Ice accumulation in commercial refrigeration equipment might not look like such a big deal at first, but it can cause multiple issues. Here’s an overview of what causes ice accumulation, what it does, and how to resolve it.

Why Does Ice Buildup Occur?

The most common cause of ice buildup in commercial refrigeration equipment is warm air. If there are damaged gaskets or faulty hinges, the door to the freezer might not seal properly and allow outside air to get in. This can also happen if the doors aren’t shut all of the way. Remind your employees to always shut the freezer doors completely after they’re finished getting any items. Ice buildup can also occur due to a broken fan or a clogged drain line; both of these issues can be repaired by a professional. 

What Can Ice Buildup Do?

This can cause your energy bills to rise and potentially damage the evaporator fans or drain lines. Ice accumulation can also cause freezer burn, which freezes the water in the food, damaging the taste and smell.

How Do You Prevent Ice Buildup?

Now that you know how troublesome ice buildup can be for your commercial refrigeration system, you’ll want to do everything you can to prevent it. Start by periodically checking the seals and gaskets for rips and tears and replacing them as necessary; they usually need to be replaced at least every 10 years. Regularly running the defrost cycle will also slowly melt any ice buildup—without affecting the quality of the food inside.
