The new PTS/PTU Series Push Through Low Intensity Infrared Tube Heaters use positive pressure with patent-pending Tube Integrity Safety System™ (TISS) designed to provide the ultimate in fire safety protection. With the TISS system, an insulated wire is placed above the reflector. A low voltage circuit continuously monitors the clearance between reflectors and ceiling for excessive heat. If heat increases due to heat exchanger failure, the wire melts, the safety circuit is broken, and the gas controls shut down.
