ICUBE™ Adaptive Defrost Refrigeration Module with Sensor

Grässlin by Intermatic has developed a new adaptive defrost module for refrigerated walk-in freezers and coolers. It is an easy, versatile, innovative and affordable way to reduce defrost cycles by 40% or more per day!  The ICUBE™ module can be field or factory installed directly on to our existing DTAV40 defrost timer. This controller provides major energy savings where walk-in freezers and display cases are used, such as in full service, casual and fast food restaurants; hospitals and health care facilities; convenience stores and supermarkets.

New Product Highlights


The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.


The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.
