Isotherm U125X000L11311AA – SP “2050” Water-Cooled Refrigeration Unit
The Isotherm U125X000L11311AA SP “2050” is a seawater-cooled refrigeration unit engineered for 125-liter marine refrigerators. Using Isotherm’s SP self-pumping cooling system, it relies on hull movement to circulate seawater through a full-flow spiral heat exchanger integrated into the drain hose. This passive method eliminates the need for electric pumps or fans, resulting in silent operation, low power consumption, and high thermal efficiency. The system uses a Secop BD35F compressor paired with a large L-shaped evaporator (16 × 7 × 8 inches) and includes a click-on mounting bracket for easy installation. A mechanical thermostat provides simple and reliable temperature control.
