Function of the SWK2000 with fuel heating
Heat is transmitted to the aluminium centrifuge and vane section very efficiently, so as the fuel enters the filter it starts to become warm. The warmed fuel prevents the filter becoming clogged by paraffin that has formed due to very low temperatures. The fuel filter heating system is controlled by a thermostat which activates the heater at 5° C, if the fuel temperature reaches 10° C the heater is switched off as the fuel heating system is not necessary. A pilot lamp located in the switch indicates when the thermostat has activated the heating system.
The system is fully protected by a fuse in the filter housing that protects the heater in the unlikely event that the heater temperature reaches 80° C, also a fuse is fitted to the heater power supply.
SEPAR 2000 filters with heater can be installed on any diesel engine with either a 12 or 24 volt electrical system. Preferred applications are trucks, buses, construction and agricultural equipment as well as stationary engine applications that are used in cold climates.
