The Isotherm SP system is a completely new technology, by means of which the system is cooled directly by the surrounding water. This means that refrigeration efficiency is completely independent of the air temperature inside the boat.

installed in 2009 I installed the system on our yacht (located in Greece) in 2009. In 2022, I had a bottleneck in the aluminum evaporator line. The cause was galvanic corrosion; the refrigerator's exterior is made of stainless steel. I hadn't thought of that at the time, so it's my own fault! Otherwise, the system works perfectly and, contrary to the product description, produces ice cubes, and we also freeze food. Of course, this only works with an O evaporator. I highly recommend this system.

Product details

The Isotherm SP system is a completely new technology, by means of which the system is cooled directly by the surrounding water. This means that refrigeration efficiency is completely independent of the air temperature inside the boat. Even on the hottest days of summer - just when a refrigerator is essential - the water-cooled Isotherm SP operates consistently and efficiently regardless of hot ambient temperatures. Without fans or pumps to remove the heat that is generated by the refrigeration compressor, the SP system consumes much less battery power and is remarkably quiet. Although heat always rises if left to the laws of nature, the Isotherm SP unit uses the natural movement of the hull to draw heat down and out through a special fitting in the galley sink drain hose. As this hose is not restricted by pumps or non-return valves, flow is completely free. Each movement of the water surrounding the boat produces a similar change of the water level inside the hose resulting in the pumping of a similar quantity of water in and out through the hull fitting.

Advantages:

  • Seawater cooling for even higher efficiency.
  • Lower power consumption.
  • Silent - no fans or pumps.
  • Heat removed by water means cooler inside the boat.
  • No extra holes in hull required and no protrusions.
  • Easy to install. Replaces the through-hull fitting for galley sink.
