The Qmark IUH Series Industrial Grade Electric Unit Heater is designed for primary or supplementary heating of factories, stores, warehouses, public buildings, service stations, or workshops.
Heating Element. Steel fins are copper brazed to low watt density, steel sheathed tubular heating elements. The elements are arranged in a uniform grid pattern and fit closely into the air discharge area to assure that all incoming air passes through the heating element. Uniform discharge of all heated air lowers internal operating temperatures and prolongs element life. The heating element is finished with aluminized paint for corrosion resistance.
High Limit Cutout. A high-limit cutout automatically shuts off current in the event of overheating and reactivates the heater when temperature returns to normal.
Finish. The cabinet is finished with an epoxy coating for excellent corrosion resistance. The finished color is neutral grey.
The quantity and wattage of Qmark IUH electric unit heaters required for a specific area should be determined by the heat loss of the structure. Small areas can be heated by one unit heater. Larger areas require multiple units. Where multiple units are required, the air discharge of each heater should support the air flow of the others to provide perimeter rotational circulation of warm air.
