All motors and contactor coils are 240 VAC and operate on the secondary of a factory-installed step-down power transformer for 480 VAC and 600 VAC heaters so a separate fan and motor control power source are not needed.
Automatic fan delay eliminates cold drafts on start-up and discharges residual heat from the heater body during shut down.
Steel fins are copper-brazed to low-watt density, steel-sheathed tubular heating elements.
5.0 and 7.5 kW models also come equipped with ceiling mounting bracket for horizontal or vertical flow mounting or any position in between.
Uniform discharge of all heated air lowers internal operating temperatures and prolongs element life.
Cabinet is finished with a polyester powder coating for excellent corrosion resistance.
Element finished with aluminized paint for corrosion resistance.
Fins and elements are arranged in a uniform grid pattern and fit closely into air discharge area to assure that all incoming air passes through heating element.
High-limit cut-off automatically shuts off current in the event of overheating and reactivates unit when temperature returns to normal.
