GENHEAT

Preheater Types

At GENHEAT we offer different types of preheaters. Which preheater is most suitable depends on the application.
Read on to find out which type of engine heater is the best fit for your application.

Coolant heaters warm up the engine by heating up the coolant and transferring the heat to the engine through the coolant. Some coolant heaters use a (electric) circulation pump to preheat the engine. These so-called forced flow heaters, or circulation heaters, warm up the coolant and pump it through the engine to provide even heat distribution.

Other coolant preheaters make use of the thermosiphon process for heat transfer. These heaters warm up the coolant and circulate it through the engine by thermal convection.

Coolant heaters

At low temperatures paraffin wax in diesel fuels can start gelling, causing the diesel to solidify and stop flowing. When the fuel can’t reach the engine, this of course causes serious problems.A similar effect can occur for oils. Low temperatures can increase the oils’ viscosity, which reduces the oil flow towards the engine and the hydraulic systems.The described problems can be prevented by making use of fuel and oil heaters. At GENHEAT we offer fuel and oil heaters from multiple brands:

Fuel and Oil Heaters

Next to increased sustainability, preheating results in more environmental benefits. Most fuel is consumed when starting the engine and bringing the engine to operating temperature, and a cold engine emits more harmful substances compared to a warm engine. A preheated engine consumes less fuel and releases less emissions, making preheating beneficial for the environment.
