CVD (Cool Vapor Defrost) technology is basically a different type of ice harvest system that allows Manitowoc to move the compressor out of the customer environment. Standard remote condenser ice machines all use compressor hot gas systems to heat the evaporator during their ice harvest cycles. To make hot gas systems work, the compressor must be as physically close to the ice making evaporator as possible. This also means the noise from the compressor is always concentrated at the ice making part of the system.
Manitowoc CVD ice machines use vapor refrigerant from the receiver tank to harvest the ice. CVD systems all use large capacity refrigerant accumulators for maximum compressor protection under any operating condition.
