Convenient, small and powerful are great words that describe our unit heaters which have been standard equipment in most high rise buildings, garages, water treatment and fire room vaults to prevent freezing. High mass steel elements and high CFM keeps outlet temperatures low for long life. For KB.s under 5KW, use the KBP Series for higher outlet temperatures. Other applications are residential garages and warehouse heating. Long life comes standard with the highest quality components custom designed for use in the KB Series Unit Heater.

Construction: All exterior and interior metal enclosure parts are made from 20GA electro galvanized steel with a rust inhibiting baked enamel finish. Smooth rounded corners and protective edge trim give an attractive modern appearance.
Adjustable Outlet Louver: Louvers direct air up or down as needed for the heating application.
Rear Intake Screen: Heavy gauge steel screen protects against foreign objects making accidental contact with the rotating fan blade.
Spiral Fin Elements: The metal sheath element is brazed with spiral fins and then molded into a coil configuration. This combination produces the best heat transfer while eliminating the potential for hot spots by positioning the element in the maximum airflow stream.
Totally Enclosed Fan Motor: Permanently lubricated cast iron with 20 cc of oil. Epoxy coated motor with enclosed rotor resists moisture and corrosion for long lasting trouble free operation.
Aluminum Fan Blade: Axial flow type fan mounted directly to the motor shaft for maximum efficiency.
Auto-Reset Thermal Cutout: Power is disconnected from the element if an overheated condition occurs. The fan continues to run to dissipate excess heat from the element. The element is reenergized automatically when the normal operating temperature returns.
Internal Controls: Magnetic contactors are standard on all 480V heaters, all 208V-1Ø, 240V-1Ø, 277V-1Ø heaters above 6-KW, and all 3Ø heaters. The control voltage is equal to the line voltage (208, 240 or 277) except for 480V models where a transformer is provided for 24V Control. Internal circuit fusing is provided when the heater ampacity exceeds 48 amps to comply with NEC standards. A fan delay is provided standard on models 12.5-KW and above to dissipate residual heat from the heating elements.
Easy Installation: A quick access panel located on the bottom of the heater allows for quick wiring and easy maintenance for the life of the heater.
Factory Installed Options:
Power Contactor: Standard on heaters above 5KW and on all 3-Phase models, optional on 2 to 6KW 1-Phase heaters.
24 Volt Control: Standard on 480V heaters, optional on all other heaters.
120 Volt Control: Control components will be modified to accept 120V control. (Not Standard)
Mounting: Choose universal or low profile ceiling bracket made from heavy gauge steel.
Rough Service: 5-Lugs are provided to securely mount heater in heavy industrial applications or marine vessels were vibration and movement are a concern. Includes 5-Hole Bracket.
