-
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.
