Wine-Mate duct split cooling systems are designed and used to provide a cold temperature between 50~65 °F for a properly insulated wine cellar. The wine cellar will maintain humidity range within 50~70% RH. These temperature and humidity ranges like in natural caves are optimized for long term storage of wine. SSH units consist of a condensing unit and an evaporator unit; they are connected by a liquid line and an insulated suction line. SSH condensing units can be located away from the evaporator unit 50 ft so that noise and compressor vibration are isolated. SSH evaporator units are designed to provide chilled air to wine a cellar through ducts and can be located up to 25 ft away to reduce noise. It also
provides more installation flexibility.
