Heavy gauge welded steel cabinet with powder coated finish and control compartment
with a hinged and latched access door, simplifying wiring installation & maintenance.
HEATING ELEMENT:
Circular copper clad steel sheath element with continuously brazed steel fins formed to
match the air delivery pattern of the fan blade.
OVERHEAT PROTECTION:
All units come equipped with automatic resetting type limit controls to de-energize the
heater should an over-temperature situation occur.
FAN and MOTOR:
Totally enclosed, single phase, permanently lubricated, thermally protected motors
with unit bearings on 3 KW – 10 KW models and sleeve bearings on 12.5 KW – 48
KW models – mounted with rubber insulators to minimize vibration and noise. Fan
assembly enclosed by a heavy gauge, close spaced, chrome plated wire guard.
LOUVER ASSEMBLY:
Louvers are individually adjustable for directional control of air flow and the entire
assembly can be repositioned in the field from down flow to up flow or
left / right directional air flow
TEMPERATURE CONTROLS:
20 KW through 48 KW units and all 480V have built in 24 Volt transformer for low
voltage remote thermostat application. 25 KW through 48 KW models available in
2-stage on special order (consult factory).
INSTALLATION:
Unit Heaters can be mounted with the motor shaft from horizontal to downward at 45°
off horizontal. Pre-drilled holes and installed threaded nuts provided to allow hanging
by threaded rods – 1
