<p>The thawing of frozen diesel engine fuel is obtained by an electrically heated belt which is mounted around the fuel filter bowl. Thus there is no contact between the heater and the fuel, so in the event of a fault in the heater there is no possibility of sparks being in contact with fuel vapour. The belt is fitted round the filter and the two ends are joined with a spring, nuts and bolts, clips, or other fasteners. A thermostat is built into the belt to switch the electric power supply to it such that the temp. is regulated between an upper limit in the degrees range 25 to 31 degrees, and a lower limit in the range 5 to 11 degrees C.</p> |
