    • Small- to medium-case construction is 20-gauge steel with larger cabinet 18-gauge steel
    • Advanced pull-through air flow design draws air across heating element for even air distribution and cooler element operation
    • Specially designed venturi outlet to meet required additional air throw in vertical position
    • Branch circuit fusing (when required)
    • Completely enclosed fan motor
    • 2-speed fan selector switch (25 to 50 kW models)
    • Optional fan-only switch for air movement with no heat or 3-phase wiring on 5 kW through 10 kW 208/240V and 15 kW 208V units (field-interchangeable)
    • Aluminum-finned, copper-clad steel sheath heating element extends life due to cooler sheath temperature and faster heat dissipation
    • 24V control transformer standard on most models, providing safer and more accurate means of temperature control. 3 kW and 5 kW, 208-277V, have line voltage controls as standard (24V control available on made-to-order basis)
    • 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)
    • No piping flues, valves or traps needed for installation
