The ideal temperature for walk-in coolers varies depending on their usage. You can measure the temperature just by using a thermometer. Generally speaking, these are the proper temperatures for commercial coolers and freezers:
Reach-in refrigerator: 35-38 degrees
Walk-in refrigerator: 35-38 degrees
Reach-in freezer: -10-5 degrees
Walk-in freezer: -10-0 degrees
Ice cream freezer: -20- -10 degrees
Remember, the temperature within your commercial refrigeration unit may fluctuate at first. Moreover, the larger the unit, the longer it will take for the temperature to stabilize. Before you stock your cooler, refrigerator or freezer with food, give it a day for the temperature to settle.
Can't seem to get your walk-in cooler to reach the ideal temperature? Be sure to do the following:
- Try leaving the doors closed for 10 minutes, and then measure the temperature again
- Teach your employees best practices for refrigerator and freezer doors
- Think about installing a thermostat specifically for your refrigeration unit
