TPI Corporation HF685TC Fan Forced Portable Heater, 4800/3600W, 240/208V

The TPI Corporation HF685TC fan forced portable heater is a 680 series heater that has a forced air fan that distributes and circulates heat through a room, providing temperature rise to 58 degrees F. The steel housing is powder-coated for resistance to corrosion and has a handle for portability, as well as a swivel base for mounting to a wall, floor, or ceiling. The finned tubular steel heating element helps draw air flow and discharge heat, and the fan moves air at 262 cubic feet per minute, with an air throw distance of 10’. The heater includes a thermostat for adjustable temperature control from 35 to 85 degrees F, as well as an internal manual reset thermal cutout switch for overheat protection. The single-phase wiring operates on either a 240V circuit at 4.8kW, or a 208V circuit at 3.6kW. The unit weighs 20 lb., includes a 6’ power cord with a molded NEMA plug, and is compliant to standards for use in the United States and Canada by United Laboratories (UL).

Electric heaters generate warmth through a central heating element that is housed in a reflective enclosure that concentrates the energy produced. An element made of a combination of metals produces heat or infrared energy by the electrical resistance created when an electric current passes through it. Fan-forced heaters pass air over the heating element to expel heat from the enclosure for greater throw and circulation. Radiant heaters do not use a fan, but warm nearby objects through energy transfer. A heater’s voltage and wiring should be matched to the electrical circuit where it is to be used. Heaters are used in a range of commercial applications that include shop floors, construction sites, and industrial buildings. All local electrical codes should be followed when installing permanent mounted electric heating equipment.

TPI Corporation manufactures industrial and commercial electrical heaters, process heat ovens, ventilation products and fans, lighting equipment, and thermostatic controls. The company, founded in 1950, is headquartered in Johnson City, TN.
