Made of heavy gauge die-formed steel, the forced air QMark MUH0521 Electric Unit Heater is ideal for garages, workshops, warehouses, factories, stores, shipping rooms, power stations and aircraft hangers. This versatile heater can be used for primary, supplementary, spot or dual-system heating. 5 kW, 208/240 volt. 

Features/Advantages:

  • 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 heater into a cooling fan
  • Heavy-gauge die-formed steel housing. Front and 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 and cooler element operation
  • Specifically designed ventrui outlet to meet that added throw as required in a vertical position
  • Individually adjustable discharge louvers to control air flow
  • 1- or 3-phase wiring on 5-10 kW 208/240V and 15 kW 208V units (field interchangeable)
  • Aluminum-finned, copper clad steel sheath heating element has a longer life because of cooler sheath temperature and faster heat dissipation
  • Fan delay feature eliminates cold drafts. Element heats up before fan cuts in, then fan continues to distribute heat after element shuts off
  • 24V control transformer standard on most models, providing a safer and 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 entire length of element areas
  • Meets all UL, NEC and OSHA requirements
