Die Formed Cabinet — Heavy 18 gauge steel, phosphate undercoated for corrosion resistance and finished in almond polyester powder coat.

Louvers — Individually adjustable louvers direct air flow up or down as needed.

Fintube Heating Elements have corrosion resistant steel fins that are furnace brazed to the tubular element to assure long life and superior heat transfer.

Fan Motor — Totally enclosed fan motor is rated for continuous duty with built-in thermal cutout and operates on same voltage as the heating circuit.

Dynamically Balanced Fan is attached with rubber vibration insulators for smooth, quiet operation. Blade pitch is carefully selected so that the volume of air moved results in the optimum discharge air temperature.


• Sub-divided Circuits with Individual Fuse Protection — Standard on all heaters with a total current draw of 48 Amps or greater. The fuse compartment is conveniently located for easy access.

• Integral 120V Control Transformer — Standard on 480V models, eliminates the need for an external control source (24V optional).

• Heavy Duty Magnetic Contactors are standard on all models.

• Thermal Cutouts open the control circuit and disconnect power to the heating elements if overheating occurs. Automatic Reset allows the control circuit to reclose and restore power when temperature returns to normal.

• Field Convertible — Combination 208/240V and 1 or 3 phase operation through 10 kW.

• Mounting Configurations — Recessed welded fasteners on top of the heater cabinet are internally threaded for suspension of unit with threaded rods. Ceiling and Universal Wall Swivel brackets are optional. The ceiling bracket lets you mount heater directly to ceiling or over-head member, simply and easily. The swivel mounting allows you to readily adjust the direction of warm air flow for maximum comfort up to 180 degrees.

Optional Features (Factory Installed or Field Installation Kits)

• Summer Fan Switch Kit — Field installable for circulating warm stratified air. Available for all models.

• Thermostat Kit — Field installable on all models. Range 40°F - 90°F.
