Engine Drive System
(Sea Frost)

If you cruise for more than a day and a continous power source is not availabl, Sea Frost's Engine Drive holdover plate system is most likely the best solution for your refrigeration needs. Its high speed, hisg capacity direct drive design keeps engine rinnung time to a minimum and won't compromise, complicate or overload your boat's electrical system.

With the Engine Drive, holdover plates(thermal energy storage) are rapidly frozen by means of a large compressor belted off the engine. Driving the compressor directly from the engine speeds the refrigeration process considerably - directly converting engine power to "cold" (and extremely efficient energy transfer) and rapidly freezing the solution in the holdover plate. Water cooling is achieved by using a flow-through condenser (heat exchanger) and the engine raw water pump. This eliminates an addtional water pump, strainer and through-hull fittings. With a well designed Engine Drive system, a day's worth of refrigeration can be accompished in under an hour while otherwise using the engine : motoring, charging your batteries, making and/or heating water.
