heat transfer.
CoilAll air passes through coil. Heating is uniform. Design assures maximum control over air delivery and temperature
of air leaving the heater. Aluminum fins die-formed for added strength – increased heat transfer. Fins mechanically
bonded to serpentine copper tube.
Motor – All motors are totally enclosed. Single phase and explosion-proof types include built in thermal overload
protection. Selected and tested for operation on specific unit heater models. All motor wiring is terminated in an electrical
junction box either supplied on the unit heater casing, or as an integral part of the motor.
Fan – Lightweight. Blades accurately balanced and pitched to move air quietly and positively – with minimum power
requirement.
Deflector BladesAdjustable horizontal air-deflector blades are standard. Vertical blades are also standard on models
