<p>The heating system is for liquid in a truck mounted hot line pavement striping system with a paint storage tank and spray guns. The heating system includes a conduit from the i.c. engine of the truck leading to a series of smaller conduits passing through the thermal oil bath, as the sole heat source for heating the oil bath. The pipe then exhausts to the atmosphere, the inner walls of the tubes having sufficient heat exchanging surface and of sufficient number to conduct sufficient heat from the exhaust gases through the conduit wall to the oil bath to heat the thermal oil. The oil surrounds tubes within the bath which contain the paint to be sprayed "hot" from the paint guns. A heat by-pass from the engine can circumvent the heating system.</p> |
