1.2 Features
• All exposed components are made of non-corrosive materials such as stainless steel, brass or aluminum.
• The “HTF” circuit includes an open, atmospherically-vented expansion tank, which effectively eliminates
the system from pressure vessel classification.
• The control system includes a sequence of status indicator lights which provide a quick function check
and trouble-shooting aid for the operator.
• The combustion chamber/heat exchanger is completely fabricated from stainless steel and is not
susceptible to corrosion. Temperature turn-down for prolonged periods of operation (such as for concrete
curing) will not harm the chamber.
• For security and environmental protection, all valves, controls, burner, pump, filters and “HTF” tank filler
are either secured behind lockable access doors or are self-lockable.
• Temperature gauges, pressure gauge, system status indicator lights and “HTF” tank level gauge are visible
to the operator even when the system is securely locked down.
• Burners approved for use with the system, come with a permanently installed pressure gauge to simplify
adjustment of gas pressure when setting up the burner.
• Door handles and hose connection couplers for the external HTF circuit are recessed so as not to create
“snag-points” when moving, shipping or delivering the unit.
