Rapid hot gas defrost

The hot-gas defrost system with demand and time control permits very short defrost cycles: only 8 minutes for laboratory refrigerators and 12 minutes for laboratory freezers. As a result, the internal temperature remains almost constant during the defrost cycle. The cabinet defrosts only when required as the controller calculates the defrost cycles based on the compressor run-time. Energy-efficient hot gas reduces the defrost time from approximately 30 to only 8-10 minutes. In addition, there is the option of initiating the defrost manually.
