Horizontal/Downflow Unit Heater, 40KW at 480V, 3Ph -
Use as auxiliary, supplementary or primary heat source in factories, stores, garages, basements, warehouses, public buildings, service stations, stock-rooms, offices, large or exposed areas or additions. One unit mounts either horizontally or vertically. Totally versatile. In addition, louvers adjust up and down for even greater control of throw direction. Louvers have stops to prevent complete closing of the discharge area. Horizontal and downflow in one unit. 360° positioning. Adjustable louvers. Aluminum-finned, copper clad steel sheath heating element has longer useful life, because of cooler sheath temperature and faster heat dissipation. Advanced pull-through air flow design draws air across heating element for more even air distribution and cooler element operation. Forced air unit heater with 10 power ratings, from 3 KW to 50 KW heating output; 208, 240, 277 and 480V. 10,230 to 170,600 BTU/hr. 1- or 3-phase wiring on 5 through 10 KW 208/240V and 15 KW 208V units (field interchangeable). Branch circuit fusing (when required to meet NEC requirements for maximum 24 amps/ckt). 2- speed fan selector switch (25 to 50 KW models). Automatic control delays fan action until heating element is warm. When thermostat is satisfied fan continues to operate until heating element is cool. By preventing circulation of cold air and expelling excess heat, comfort level is raised and component life is extended. Automatic reset linear thermal cut-out capillary type, provides protection over entire length of element area. (Manual reset protection available on made-to-order basis). Specially designed venturi outlet to meet that added throw required in vertical position. Ruggedly built, yet lighter weight for easier installation. No piping flues, valves, or traps. Heavy gauge die-formed steel housing. Large, dynamically balanced fan blades provide maximum air flow with minimum turbulence and noise. Rugged, totally enclosed motor. 480 Volts, 3 Phase, 48 Amps. Mounting brackets sold separately.
