3.3 KW THROUGH 50 KW SUSPENDED FAN FORCED UNIT HEATERS AVAILABLE IN 1 OR 3 PHASE FOR ALL STANDARD VOLTAGES FROM 208V TO 480V. CAN BE MOUNTED TO PROVIDE HORIZONTAL OR VERTICAL DISCHARGE.
These unit heaters are recommended in low bay areas with maximum 15 to 18 foot ceilings. These should be concentrated along outside wall or other areas of greatest heat loss; spaced to set up a generally circular air movement, each heater supporting the air stream of the other.
FEATURES:
CONSTRUCTION: Heavy 18 gauge welded steel cabinet with powder coated finish and control compartment housing a master terminal board with a hinged and latched access door, simplifying wiring, installation and maintenance.
HEATING ELEMENT: Copper clad steel sheath element with continuously brazed steel fins formed to allow side draw through air flow.
OVERHEAT PROTECTION: All units come equipped with automatic reset type limit controls to de-energize the heater should an over-temperature situation occur.
FAN and MOTOR: Totally enclosed, 1-speed, 1-phase, permanently lubricated, thermally protected motors with unit bearings on 3 KW - 20 KW models. Totally enclosed, 2-speed, 1-phase, permanently lubricated, thermally protected motors with sleeve bearings on 25 KW - 50 KW models. Fan over-ride purges unit of residual heat at shutdown.
LOUVER ASSEMBLY: Louvers are individually adjustable for directional control of air flow up to 15 degrees from straight horizontal. Optional diffusers available for down flow (vertical discharge) applications.
TEMPERATURE CONTROLS: Optional low voltage and line voltage thermostats available with an adjustable temperature range of 40F to 110F. Units with model numbers ending in CA1 are factory wired for low voltage controls. 25 KW through 50 KW units are designed for two stage heating operation.
INSTALLATION: Unit Heaters can be mounted for horizontal or vertical discharge. Applications up to 6000 ft. See UH Series above 6000 ft.
FIELD INSTALLED OPTIONS:
- In-unit or wall mounted temperature control thermostats low or line voltage.
- Summer fan switch to operate the fan only.
- Power disconnect switch.
- Heat stratification thermostat.
