ETU - Pull Through (Negative Pressure) Radiant Infrared Tube Heaters

Pull-Through System (negative pressure or vacuum)

• Products of combustion are pulled through the combustion chamber for increased radiant efficiency and greater safety
• No draft hoods, totally enclosed combustion chamber
• Heavy duty draft inducer with permanently lubricated, totally enclosed, fan cooled, and heavy duty ball bearing motor for maintenance-free operation
• Draft inducer can be rotated 45 or 90 degrees for sidewall venting
• Tubes & Reflectors are bulk shipped for easy field assembly
