The Qmark MUH Series Electric Unit Heater is a heavy duty, fan forced unit heater can be mounted horizontally or vertically. The versatility of the heater allows for use in commercial and industrial applications such as heating factories, warehouses, garages, stores, shipping areas, power stations, and aircraft hangers.
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.
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. However, the 3KW and 5KW units with a 208 Volt, 240 Volt, 277 Volt, 347 Volt, or 600 Volt rating, have line voltage control as standard (24V control available on made-to-order basis for these units).
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.
Meets all UL, NEC, and OSHA requirements.
The Qmark MUH Series Electric Unit Heaters offer an attractive, versatile, and durable heating source. The heater may be mounted to discharge the heated air either horizontally or vertically. When the heater is mounted for vertical discharge, it is recommended that the heater be positioned so
that the access door will open away from the wall to provide greater access to the wiring and control compartment.
When determining where to mount the heater, it is important to NOT block the air intakes or exhaust in any manner and keep combustible materials, such as crates, drapes, etc., away from heater. Do NOT install the heater behind door, furniture, towels or boxes.
After the heater is installed, the louvers may be positioned to direct the heated air in the desired direction. When the heater is installed for horizontal discharge, the louvers should direct the air either straight ahead or downward. Directing the air upward may cause the heated air to remain in the ceiling area and waste energy.
