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 & maintenance.
Copper clad steel sheath element with continuously brazed steel fins formed to allow side draw through air flow.
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. All motors mounted with rubber insulators to minimize vibration & noise. Fan over-ride purges unit of residual heat at shutdown.
Louvers are individually adjustable for directional control of air flow up to 15° from straight horizontal. Optional diffusers available for down flow (vertical discharge) applications.
Optional low voltage and line voltage thermostats available with an adjustable temperature range of 40°F to 90°F. 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.
Unit Heaters can be mounted for horizontal or vertical discharge. Applications up to 6000 Ft. See UH Series above 6000 Ft.
ABS (American Bureau of Shipping) type approved.
FIELD INSTALLED OPTIONS:
- In-unit or wall mounted temperature control thermostats low or line voltage.
- Power disconnect switch.
- 25-50KW models are wired for single or two stage heating and have two speed motors.
- Air delivery and motor data on dual voltage units reflect higher voltage.
Heavy Gauge steel cabinet with powder coated finish and control compartment housing a master terminal board. The control compartment allows for access through a hinged and latched door, simplifying wiring, installation, and maintenance.
The heating element is a copper clad steel sheath element with continuously brazed steel fins formed to allow side draw through air flow.
All units come equipped with manual reset type limit controls to de-energize the heater should an over-temperature situation occur.
FAN & MOTOR:
Single speed, single phase permanently lubricated, thermally protected motors with ball bearings. The fan override purges the unit of residual heat at shutdown.
60 KW and 70 KW are three stage; 80 KW, 90 KW, & 100 KW are four stage.
SC5100 FACTORY INSTALLED ELECTRONIC STEP CONTROLLER:
The optional factory installed step controller is a first on last off sequencer that will cycle the unit heater stages through an optional wall thermostat. Additionally, the step controller can be controlled by any building management system with 4 to 20 MA or 0 - 10 VDC field supplied control signal.
