Water-cooled Self-Pumped Cooling Units with Intelligent Temperature Control +

The ITC Digital Display in conjunction with a Holding Plate forms a cooling unit called ITC+, where the storing energy effect is amplified thanks to the wide range of eutectic plates available. The intelligent energy management system charges the holding plate when batteries are at high charge level (engine running or on-grid) and restitutes progressively the cold energy to reduce drain on batteries when used as single source of energy.

Self-pumping sea-water cooled units

The Isotherm SP units cool with the use of seawater. This method has the advantage that the heat exchange is made via a water cooled condenser. 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 condenser, the SP system consumes less battery power and is remarkably quiet.

The Isotherm SP unit uses the movements of the hull to draw heat down and out through a special fitting in the galley sink drain hose. The flow is completely free inside the draining hose, so each movement of the surrounding water produces a similar quantity of water level inside the hose, which results in pumping an equivalent amount of water in and out. By designing a special hull fitting containing a non restricting, fullflow spiral heat exchanger for cooling the heated refrigeration agent, an extremely efficient cooling system is created.

As the hull fitting is situated away from the boat’s center of gravity, the smallest movement of the hull or mast of sailing boat is sufficient to create a pumping action. This movement results in constant withdraw of warm water and intake of cold water which also prevents fouling.
