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 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 & 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 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. 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 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 the entire length of element areas
Meets all UL, NEC & OSHA requirements
