What You Need to Know About Humidity in Commercial Coolers

Mar 16, 2022 | refrigeration

Commercial coolers help maintain the proper temperature in order to preserve the contents and prevent them from spoiling. While cooling almost always brings humidity and condensation, well-functioning units should be able to prevent these from building up. Here A/C and Refrigeration explains everything you need to know about proper humidity in commercial coolers.

Humidity in Commercial Coolers

What Are the Ideal Humidity Levels for Each Type of Cooler?

It pays to know the ideal humidity level for your commercial cooler. The following are examples of some of the different levels:

  • Floral coolers – These should have about 90% relative humidity at temperatures between 35 and 45 degrees Fahrenheit to ensure the flowers don’t dry out and fall apart. Floral coolers also require gentle airflow to keep the flowers fresh. 
  • Fresh fish and meat cases – These should have 85% to 90% relative humidity at 35 degrees Fahrenheit. This prevents the meat from losing its weight as a result of surface evaporation.
  • Beer and beverage coolers – These should have 60% to 75% humidity at 35 degrees, which is an ideal range for beers that have corks in them. If it’s too low, the cork may dry out; if it’s too high, mold may develop and enter through the cork, tainting the beer. 
  • Wine and beverage coolers – These should have 55% to 70% humidity at 45 degrees. Like beer corks, wine corks may dry out when the humidity is too low. When exposed to air, the top of the cork can crack or shrink, spoiling the wine. 
  • Produce display cases – These should have 60% to 75% humidity at 55 degrees. Your customers associate the appearance of the fruits and vegetables with their quality, so make sure they look fresh. A loss of water may make them look shriveled and unappealing. 

What Are the Common Humidity Issues in Commercial Coolers?

In most cases, commercial coolers can easily push the humidity out. However, too much humidity can be damaging. If the components of the unit are unable to eliminate the humidity, they’ll work twice as hard to push it out. This can lead to wear and tear in your cooling unit and may even raise your energy bills. 

Here are some humidity and condensation signs to watch out for:

  • Frost and ice building up on metal or glass surfaces inside a walk-in unit
  • Ice building up on walls, cold surfaces and fixtures
  • Stored contents showing signs of water buildup or damage
  • Puddles around your cooling unit
  • “Misty-feeling” air inside the unit

The best way to prevent these issues is to have certified technicians perform regular inspections and maintenance. These cooling experts will inspect your refrigeration system for problems and repair any damage they find. For further inquiries, reach out to our experts at A/C and Refrigeration.
