QMark® MUH Electric Unit Heater - 50 kW - MUH504

Made of heavy gauge die-formed steel, the forced air QMark MUH Electric Unit Heater - 50 kW 480V, model MUH504, 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.
Features/Advantages:
- Mount horizontally or vertically
- Completely enclosed fan motor
- Optional control kits are field installable
- 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
