Diesel engine pre-heaters

Kanthal® materials are used to start diesel engines operating in cold climates. Kanthal® strip and wire help to pre-heat the engine and provide clean performance by reducing emissions and minimizing "white smoke". An intake air pre-heater is used on the intake channel in order to increase air temperature supplied to the cylinder for combustion.

The heater works in two modes:

Pre-heat mode

While turning on the engine, the air going through is heated in order to reach minimum needed ignition temperature

Post-heat mode

Used to warm up combustion in order to minimize "white smoke". White smoke is a mixture of air and oil that is not fully combusted, which is exhausted until the engine reaches working temperature. In this mode the diesel pre-heater works as an environmental friendly complement to reduce pollution levels emitted into the environment
