Isotherm U060X000P11311AA – SP “2055” Water-Cooled Refrigeration Unit
The Isotherm U060X000P11311AA SP “2055” is a compact, energy-efficient seawater-cooled refrigeration system designed for marine iceboxes up to 60 liters. Using a self-pumping seawater cooling method, the system achieves high thermal efficiency without the need for fans or electric pumps. The passive full-flow spiral heat exchanger uses boat motion to circulate seawater, continuously removing heat from the condenser. Equipped with a Secop BD35F compressor and a small flat evaporator (14 × 5 inches), the unit provides cooling performance equivalent to 2.1 cu.ft. fridge or 0.7 cu.ft. freezer applications. A mechanical thermostat ensures simple and reliable temperature control.
