Commercial grade high temperature manual reset for safety. High mass, tubular element for longer life. Fan delay eliminates cold draft on startup and disperses residual heat on shutdown.
The CEH Industrial Unit Heater Calculate the heat loss of the area to be heated. It is recommended that one of the following methods be used: ASHRAE Guide and Data Book (The American Society of Heating, Refrigeration & Air Conditioning Engineers); The NEMA Handbook (The National Electrical Manufacturer's Association); or the ACCA Manual J (The Air Conditioning Contractors of America). The layout of the space to be heated must be taken into consideration to determine the selection of the best size heater and air displacement. Most applications benefit from a combination of vertically and horizontally discharged air delivery. In buildings with large doors that are frequently opened, use a high velocity heater with horizontal air flow across the opening, or use an infrared heater.
In smaller areas where comfort is a prime consideration, more heaters of smaller capacity are recommended. Smaller KW heaters are also recommended for low mounting heights to avoid discomfort and increased noise levels. Additionally, there is better air distribution by using a greater number of lower KW heaters Fan forced unit heater shall be UL Listed and rated at 208, 240, 277 or 480 Volt. Horizontal or vertical mounting shall be possible to direct discharged air. External cabinet shall be constructed of 20 gauge high quality steel. All metal surfaces of the cabinet, external and internal, shall be finished with a baked on powder coat paint system. Fan shall be aluminum blade axial flow type, and mounted directly to the motor shaft. Motor shall be shaded pole, industrial rated, with an inherent overheating protection device. Heating elements shall be sealed in magnesium powder and protected by metal sheathing, over which aluminum fins are applied. Heater shall be equipped with manual reset thermal cut out for over temperature protection. Fan motor circuit shall be thermostatically controlled, allowing fan to remain operating after the elements have shut off, discharging the residual element heat. Wiring compartment shall have convenient access door with captured hardware.
