Refrigeration Solutions

Refrigeration can represent a significant portion of the electric bill for restaurants, groceries and convenience stores. Businesses can save energy and money with incentives provided for refrigeration controls and the purchase of new energy-efficient equipment and retrofits for existing equipment. Businesses can save money by upgrading to high-efficiency display coolers.If replacing equipment is not a viable option, custom add-ons and efficient component retrofits can improve the performance of existing refrigeration systems.

Refrigeration Equipment

Scroll Compressors
Scroll compressors help to efficiently match capacity to the desired load of coolers and freezers. By matching capacity, the compressors can reduce cycling rate and increase the reliability of the compressor.

High-Efficiency Evaporator Fan Motors
Evaporative fan motors work in refrigeration systems to direct air into the cooling units and then into the coolers or freezers.

Strip Curtain for Cooler or Freezer
Strip curtains in a cooler or freezer will prevent warm air from entering and cold air from exiting. These curtains are easy to install and are an immediate impact.

Refrigerant Controls

Door Heater Controls for Cooler or Freezer
When replacing the doors in a cooler or freezer is not an option, businesses can use door heater controls to efficiently cycle glass heaters as needed. These controls will prevent the glass doors from fogging while only running the heaters as needed.

Evaporator Fan Motor Controls
Evaporator fan motor controls are installed in walk-in coolers and freezers to monitor the refrigerant flow. These systems will reduce the speed of an evaporator fan when the unit’s compressor is turned off, reducing the energy use and taking load off of the compressor.

Floating Head Pressure Controls
Floating head pressure controls work to reduce energy used in refrigeration by decreasing the pressure exiting the cooler compressor.
