Isotherm thermostat for Cruise series
Isotherm SP fitting
This fittting is a replacement for Isotherm SP systems and does not include valve and zinc.
Isotherm SP is a sea water cooled refrigeration system for sailing yachts and power boats. This unique system means reduced power consumption and noise level. It has no fan or pump. The sea water cooled skin fitting/heat exchanger replaces the air cooled condenser and cooling fan. The heat is transferred directly to the surrounding water instead of being circulated as hot air inside the boat.
