Tasks
Combustion engines requiring immediate operational readiness must be preheated before starting. The well-known cold
start problems are eliminated and the engine can be operated at full load from the beginning. Furthermore, cold start wear
is considerably reduced. Typical fields of application for this type of pre-heater units are e.g. emergency power units (Diesel
engine + generator) or locomotives and ships (Diesel engine for propulsion).

Unit functions
While the combustion engine is cold and out of operation, the cooling agent is pumped through the cooling loop of the combustion
engine and through the circulation heater. The cooling liquid is circulated by a pump mounted on the pre-heating
unit.Preheating of the cooling circuit provides a homogeneous heating of the motor. Once the cooling system is heated, the
temperature is held constantly at the desired set-point. The heater is switched off, when the engine is in operation. A check
valve mounted on the heater prevents the coolant to circulate through the heater during normal operation of the engine.
