Until relatively recently marine refrigeration was typically powered by the main engine via a belt-driven compressor. These systems usually comprised a standard, automotive air-conditioning compressor, a custom-made, water-cooled heat exchanger and a locally-manufactured stainless steel cabinet.
The system’s weak link, obviously, is this: if the engine’s not running neither is your refrigeration, and every time you extract food or drinks the fridge loses cooling performance.
As luck would have it, there is a relatively inexpensive kit to supplement and improve the cooling system. This kit comprises a small, aluminium cold plate (evaporator), a Danfoss (Secop) Direct DC compressor and a thermostat – and it retails for under $1,000.
As a supplement to the existing mechanical system, you’ll have a no-nonsense, air-cooled refrigeration system that will maintain your fridge 24/7.
