steel walk-in coolerHere are some ways to help you save energy costs on your walk-in refrigerator or walk-in freezer.

  • Properly seal all penetrations in walk-in.
  • Replace worn or damaged door seals.
  • Periodically, check gaskets between panels to make sure they are not cracked or weathered. If so, check with your local health codes for the correct procedure to follow as far as repair and replacement.
  • Do not prop door open for an extended period of time.
  • Add strip curtains or air curtains to your walk-in for extra protection from air infiltration when door is open.
  • Make sure the lights are off when exiting the walk-in. Lights produce heat, which will cause your unit to run more to hold its optimal temperature.
  • Make sure there is nothing stacked around the coil to restrict airflow.
  • Make sure fan motors are balanced and running at optimum speed. Clean fan blades to reduce drag.
  • Use an evaporator with an EC Motor.
  • Install refrigeration away from doors.
  • Keep condenser coils clean.
  • Utilize Smart Defrost Kits.
  • Set defrost frequency at minimum requirements.

    can you tell me what the temperature range for DBR or NSF requirements are (min. to max.) for commercial walk-in refrigerators and freezers for a food service establishment

      The NSF requires that walk-in cooler air temperature be kept at 40 degrees F or below. The requirements for a walk-in freezer are 0F or below. However, most restaurants keep their freezers set at -10F.

    Do I need to turn off my walk in freezer to let it dry out, it’s two years old or is this a myth please help?

      The freezer should be turned off and cleaned out occasionally in its lifetime. If the interior has icing in it, you may need to dry it out and fix any underlying issues that are causing it. And the refrigeration equipment should have preventive maintenance, depending on the environment. That should be set up between the you and the service provider you use to take care of your equipment.
