Boat refrigeration unit U100X000L11311AA

air cooled

Isotherm SP units use sea water for cooling. This method has the advantage of carrying out the heat exchange through a water-cooled condenser. The seawater-cooled Isotherm SP unit operates at a high level of efficiency. With no fans or pumps to dissipate the heat generated by the condenser, the SP system requires less power and operates extremely quietly. The Isotherm SP unit uses hull movements to conduct heat downward and expel it through a special galley sink drain hose fitting. The flow is completely free inside the exhaust pipe, so every movement of the water surrounding the vessel generates a constant change in the water level inside the pipe, which results in a constant amount of water being pumped in and out. By designing a special hull clamping system that contains a non-binding, spiral, full-flow heat exchanger to cool the heated refrigeration agent, a highly effective cooling system is created. Because the system is located far from the vessel's center of gravity, the smallest movement of the hull or mast of a sailing vessel is enough to create a pumping action. This movement translates into a constant flow of hot water and a supply of cold water which also prevents any blockages.
