HT310/HT322 Engine Water Heater is applied to various engine coolant preheating for its fine cast aluminum enclosure, flame-retardant engineering plastics end closure and multiple installation methods, which is easy and convenient to use. 
If the outside temperature is lower than 4℃, the engine coolant and lubricant may condense into solid state, losing their lubrication and cooling properties during cranking, which will damage the engine. Thereby, engine heater should be installed to ensure normal starting and running of the engine when the outside temperature is lower than 4℃.
