Made of heavy gauge die-formed steel, forced air QMark MUH Electric Unit Heaters are ideal for garages, workshops, warehouses, factories, and shipping rooms. These versatile heaters may be used for primary, supplementary, spot, or dual-system heating.

Applications: Factories, Warehouses, Garages, Stores, Shipping Rooms, Power Stations, Aircraft Hangers

Features

  • Mount horizontally or vertically
  • Completely enclosed fan motor
  • Optional control kits are field installable, increasing MUH adaptability to the specification market
  • Summer fan kits are available to adapt the heater into a cooling fan
  • Heavy-gauge die-formed steel housing. The front & back is a neutral grey, the wrap-around steel section is a statuary bronze color
  • Ruggedly built, yet lighter weight for easier installation. No piping flues, valves, or traps
  • Advanced pull-through air flow design draws air across the heating element for more even air distribution & cooler element operation
  • Specifically designed venturi outlet to meet that added throw as required in a vertical position
  • Individually adjustable discharge louvers to control airflow
  • 1- or 3-phase wiring on 5-10 kW 208/240V & 15 kW 208V units (field interchangeable)
  • Aluminum-finned, copper clad steel sheath heating element has a longer life because of cooler sheath temperature & faster heat dissipation
  • Fan delay feature eliminates cold drafts. The element heats up before the fan cuts in, then the fan continues to distribute heat after the element shuts off
  • 24V control transformer standard on most models, providing a safer & more accurate means of temperature control. 3 kW and 5 kW, 208-277V, have line voltage controls as standard
  • Automatic reset linear thermal cut-out, capillary type, provides protection over the entire length of element areas
  • Meets all UL, NEC & OSHA requirements
