1 OVERVIEW
HT Series Heater enjoys wide application on various engine coolant preheaters. It has fine cast aluminum
enclosure and self-extinguishing engineering plastics end closure, multiple installation ways and easy and
convenient use.
If during cranking the outside temperature is lower than 4ºC, engine coolant and lubricant may condense
into solid state and lose their lubricating and cooling properties, which can damage the engine. Engine
heater should be installed to ensure normal starting and running of the engine when the outside
temperature is lower than 4 ºC.
HT Series Water Heater combines the following features: cast stainless steel inner pipes and end closure
with high corrosion resistance; power and heating light indicators; 3 kinds of heaters with different heating
temperature are optional (Standard heater: 40ºC; 50ºC and 60ºC heaters are need to be customized).
This product is suitable for various engine with (0~13.1)L displacement.
Please login our company's official website to select heaters.
