1 OVERVIEW
During cranking, if the outside temperature is lower than 4ºC, engine lubricant may lose its lubricating
properties, which can damage the engine. Engine oil heater should be installed to ensure normal
starting and running of the engine when the outside temperature is lower than 4 ºC.
HTL series engine oil heater adopt cast stainless steel inner pipes and end closure with high corrosion
resistance.
This product is suitable for various engines with (2~110)L engine oil volume.
2 PERFORMANCE AND CHARACTERISTICS
a) Stainless steel inner pipes and end closure with high corrosion resistance and solid features;
b) The inner pipes have long service life with the benefit of the low power of the unit areas.
c) All-in-one design, compact structure and small volume.
