Berko MUH0341 QMark Unit Heater 3Kw 480V 3-Phase 3.6A Qmark Type MUH Unit Heater mounts either horizontally or vertically. Totally versatile. For factories, warehouses, garages, stores, shipping rooms, power stations, aircraft hangers. Can be used for primary, supplementary, spot, or dual-system heating.

There are a wide range of optional control kits that are field installable, increasing the MUH adaptability to the specification market.

Features:

• Forced air unit heater with 10 power ratings; from 3KW to 50 KW heating output; 208, 240, 277 and 480V, 10,230 to 170,500 BTU/hr.
• 32 compatible models (no need to try to assemble a heating system from 70 or 80 models!)
• Heavy gauge die-formed steel housing. Two-toned, smartly styled.
• Advanced pull-through air flow design draws air across heating element for more even air distribution and cooler element operation.
• Specially designed venturi outlet to meet that added throw as required in vertical position.
• Branch circuit fusing (when required).
• Completely enclosed fan motor.
• 1- or 3-phase wiring on 5 through 10 KW 208/240V and 15 KW 208V units (field interchangeable).
• Aluminum-finned, copper clad steel sheath heating element has longer useful life, because of cooler sheath temperature and faster heat dissipation.
• 24V control transformer standard on most models, providing a safer and more accurate means of temperature control. 3KW and 5KW, 208-277V, have line voltage controls as standard (24V control available on made-to-order basis).
• Automatic reset linear thermal cut-out, capillary type, provides protection over entire length of element areas (Manual reset protection available on made-to-order basis).
• 2-speed fan selector switch (25 to 50 KW models).
• Fan delay feature eliminates cold drafts. Element heats up before fan cuts in, then fan continues to distribute heat after element shuts off.
• Ruggedly built, yet lighter weight for easier installation. No piping flues, valves, or traps.
• Individually adjustable discharge louvers to control air flow.
• Choice of optional diffusers for variety of air patterns, maximizing heat concentration and coverage in the vertical position.
• Meets all UL, NEC, and OSHA requirements.
