Product Details
The unit heater is designed for horizontal or vertical mount downflow installation, featuring a capacity of 15kW at 480V, 3-phase, and serves as an auxiliary, supplementary, or primary heat source in various settings including factories, stores, garages, basements, warehouses, public buildings, service stations, stock-rooms, offices, and large or exposed areas. This versatile unit can be positioned horizontally or vertically with 360° positioning and adjustable louvers for optimal throw direction control; louvers are equipped with stops to prevent complete closure of the discharge area. Constructed with an aluminum-finned, copper-clad steel sheath heating element that ensures a longer useful life due to cooler sheath temperatures and enhanced heat dissipation, it features an advanced pull-through air flow design that draws air across the heating element for improved air distribution and cooler operation. The forced air unit heater offers 10 power ratings ranging from 3 kW to 50 kW heating output, supporting voltages of 208, 240, 277, and 480V, translating to an output of 10,230 to 170,600 BTU/hr, with options for 1- or 3-phase wiring on 5 through 10 kW 208/240V and 15 kW 208V units (field interchangeable). It includes branch circuit fusing when necessary to meet NEC requirements for a maximum of 24 amps per circuit. A 2-speed fan selector switch is available for 25 to 50 kW models, while an automatic control mechanism delays fan action until the heating element reaches a warm state, ensuring the fan continues to operate until the heating element cools down after the thermostat is satisfied. This feature prevents cold air circulation and helps expel excess heat, enhancing comfort and prolonging component life. Additionally, an automatic reset linear thermal cut-out capillary type provides protection along the entire length of the element area, with manual reset protection available upon request. The heater also boasts a specially designed venturi outlet for increased throw in vertical positions and is ruggedly built yet lightweight for easier installation, with no need for piping flues, valves, or traps. The heavy gauge die-formed steel housing and large, dynamically balanced fan blades are designed to deliver maximum airflow with minimal turbulence and noise.
