The best way to spend less on commercial refrigeration
Refrigeration can represent up to 50% of monthly energy expenses for grocery and convenience stores, industrial food processors, hotels and inns, and hospitals. Spend less on commercial refrigeration by combining basic maintenance with energy-efficient upgrades.
- Clean cooling coils several times a year
- Shade outdoor coils from the sun and allow air to circulate around them
- Make sure doors on freezers, refrigerators, and display cases seal tightly
- Check door gaskets and auto-closers, and repair or replace if they are damaged or in poor condition
- Have units serviced regularly to clean condensers and evaporators, and to check operation of fans and defrost systems
- In refrigerated cases, replace T12 fluorescent lighting with LEDs—they generate less heat, easing the cooling demands on refrigerated equipment.
- If you have door heaters, add humidity-based heater controls so they don’t run continuously
- Install night curtains to reduce the energy needed to cool open cases overnight
- Use an outside air economizer to ease the demand on your compressor
- If you’re replacing your evaporator fans, consider high-efficiency motors and controls
- When buying a new compressor, look for energy-efficient discus or scrolling models—both use less energy than standard compressors and can last up to 33% longer
- Choose ENERGY STAR® certified commercial reach-in units with solid or glass doors—and talk to us about financing options.
