Benefits
PEREGRINE diesel coolant pre-heaters are mounted externally to the engine and provide many advantages over heaters fitted directly within the engine or radiator pipework.
• Prolonged heater life: Not only is there sufficient space in PEREGRINE coolant heaters for a direct control thermostat to be fitted within the heater body, but the space also allows us to use relatively large heating elements, thereby reducing the element watts-density and surface temperature, and thereby giving a prolonged heater life.
• More effective heating: Using an external PEREGRINE diesel coolant heater unit (which is connected by hoses to two points on the engine) means that the heated water can be introduced directly to the block where the heat is required.
• Thermostat Control: Being controlled by a thermostat, the engine’s coolant temperature will be maintained at a specified level irrespective of any ambient temperature fluctuations, and the heater will of course switch off should the engine be operated. The heater may also be replaced without the need to drain down the engine’s cooling system by fitting a valved heater kit.
• IP66 Rated: All of our Weatherproof heaters are now IP66 rated (DLW, DSW, XLW)
