Isotherm U100X000L11311AA – SP “2057” Water-Cooled Refrigeration Unit
The Isotherm U100X000L11311AA SP “2057” is a compact seawater-cooled refrigeration system for 100-liter marine refrigerators. Using the SP self-pumping cooling method, the unit circulates seawater through a full-flow heat exchanger integrated into the sink drain hose, eliminating the need for fans or electric pumps. This passive system significantly reduces power consumption while providing strong cooling performance with the Secop BD35F compressor. The L-shaped evaporator (10 × 4 × 14 inches) with a click-on mounting bracket maximizes internal space and cooling efficiency. A mechanical thermostat ensures robust, simple temperature regulation.
