PEREGRINE single and twin element thermostatic engine coolant heaters ensure engine start-ups all year round.

Our range of thermostatic engine coolant preheaters employ thermosiphon heating technology which is a passive heating system that circulates warmed coolant by thermal convection. For optimal performance, the heater should be installed at the lowest point in the system.

Thermostatic engine coolant heaters offer several benefits that make them valuable in certain situations. In cooler climates, a preheated engine starts much easier, reducing wear and tear on the starter motor and battery. The thicker oil in cold engines flows poorly, causing increased friction and potential damage during startup. Preheating thins the oil, ensuring proper lubrication. Additionally, a warm engine burns fuel more efficiently, reducing emissions and fuel consumption. This is especially relevant for larger engines like those in trucks, generators, or boats, where even small efficiency gains can translate to significant fuel savings.
