ABSTRACT:
A heated thermal filter cover maintains a fluid filter, and fluid within the filter, above a gelling temperature of the fluid. The filter cover includes a soft or flexible receptacle which is generally circular in top plan and an electrical resistance wire. The receptacle includes a circular wall and a bottom which define an upwardly opening chamber sized to receive the filter. A resistance wire is placed inside the chamber, preferably at the bottom of the chamber and adjacent the inner surface of the wall. Lead wires connect the resistance wire to a source of electricity, such as the electrical system of a truck or a battery. The wall and bottom of the receptacle are both made of two plies of fleece coated fabric, the two plies being assembled together so that the fleece surfaces face each other so that the wall and bottom of the receptacle will insulate the chamber. The outer ply is preferably a fleece backed vinyl and the inner ply is preferably a thermal fleece. The receptacle is closed by a draw string at the top of the wall. The resistance wire draws only about 0.7-1.1 amps to allow the filter cover to be operated for long periods of time without the engine operating and without substantially draining the battery.
