Even on the hottest day the water-cooled Isotherm SP operates consistently at an extremely high level of efficiency. Without fans or pumps to remove the heat generated by the compressor, the SP system consumes much less battery power and is remarkably quiet. All Compact refrigeration units have a 4-½ foot line set.

The Isotherm SP System uses a patented thru-hull that removes heat through the superior cooling physics of water. This method is completely indepen dent from the air temperature inside the boat so even on the hottest days the water-cooled Isotherm SP operates consistently at an extremely high level of efficiency. Working without fans or pumps to remove the heat generated by the compressor, the SP system consumes much less battery power and is remarkably quiet.
The Isotherm SP unit uses the natural pumping motion of the hull to exchange heat through a special fitting that can replace the galley sink drain thru-hull. The flow is completely free inside the galley drain hose, so each movement of the surrounding water carries heat away into the water. The special thru-hull fitting contains a non restricting, full flow spiral heat exchanger for cooling the heated refrigeration agent, thus creating an extremely efficient cooling system. Even in the calmest waters, the natural physics of molecular heat transfer of water carries away heat. In fact, the SP System still functions sufficiently to cool refrigerant even when the boat is hauled out by creating a chimney effect to carry away heat through the natural convection of warm air up through the pipe.
The special alloy of the fitting is resistant to electrolysis and the growth of barnacles or grasses. The SP system comes complete with zinc and sea cock.
Isotherm specializes in dependable, energy-efficient systems which are backed by the exclusive Isotherm 5-year warranty on all compressors so you'll have the confidence of knowing you have purchased the best!
