OVERVIEW
HWP40-3/HWP60-3 forced circulation engine water heater is composed of 3 parts (control section,
water pump and water heater).
If the outside temperature is lower than 4ºC, engine coolant and lubricant may condense into solid
state and lose their lubricating and cooling properties during cranking, which can damage the engine.
Thus engine heater should be installed to ensure normal starting and running of the engine when the
outside temperature is lower than 4ºC.
HWP40-3/HWP60-3 forced circulation engine water heater combines the following features: cast
stainless steel inner pipes and end closure with high corrosion resistance; heating and overheat light
indicators; user-defined coolant set point; dry heating and overheat protection.
This product is suitable for various engine with (15~50)L displacement.
