Description
The SPHD uses a tank, surrounded by an oil jacket. filled with heat transfer oil. The heat
transfer oil is heated by a diesel fired burner. The temperature of the product and the heat
transfer oil is automatically maintained by electronic temperature controls located at the op-
erators station.
An optional tack tank is available to pre-heat the tack oil being used when making road re-
pairs. The tack tank is heated with an independent diesel burner and controlled with a thermo-
stat located at the operators station.
A pump may be installed on the tack tank to pump the tack material through dispensing equip-
ment, such as a hose and wand. The pump is driven by the hydraulic system. The plumbing is
purged of tack material when finished to prevent plumbing freeze-up. This is done by revers-
ing the pump to suck the material out of the system. An optional flush tank may also be in-
stalled to further flush the system of any remaining material.
The dump hopper offers controlled discharge of the contents onto a shoveling platform, or di-
rectly onto the road surface if desired. The dump hopper is hydraulically operated by a scissor
hoist remote controller located near operators station.
