Chill the product, not the air

CUES Refrigeration Controller

Chilled Unit Energy Saver – CUES is a simple retrofit device that contains a high-tech food simulant with the same thermal characteristics (thermal conductivity and thermal mass) as typical food products. CUES is placed directly over the existing thermostats (thermistors or probes) within the refrigeration system, ensuring that the refrigerator reacts to changes in food temperature, not air. This results in a more efficient refrigeration cycle, where the individual compressor cycle lasts longer but frequency is reduced by up to 80%. Grocery and convenience stores can realize energy savings of up to 33% without any compromise to food safety or quality.
