• Heavy gauge die formed steel housing. Two-toned, smartly styled.
• Advanced pull through air flow design draws air across heating element for more even air distribution and cooler element operation.
• Specially designed venturi outlet to meet that added throw as required in vertical position.
• Branch circuit fusing (when required).
• Completely enclosed fan motor.
• Aluminum-finned, copper clad steel sheath heating element has longer useful life, because of cooler sheath temperature and faster heat dissipation.
• 24V control transformer standard on most models, providing a safer and more accurate means of temperature control. However, the 3KW and 5KW units with a 208 Volt, 240 Volt, 277 Volt, 347 Volt, or 600 Volt rating, have line voltage control as standard (24V control available on made-to-order basis for these units).
• 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).
• 2-speed fan selector switch (25 to 50 KW models).
• Fan delay feature eliminates cold drafts. Element heats up before fan cuts in, then fan continues to distribute heat after element shuts off.
• Ruggedly built, yet lighter weight for easier installation. No piping flues, valves, or traps.
• Individually adjustable discharge louvers to control air flow.
• Meets all UL, NEC, and OSHA requirements.
