Space-Ray Infrared Heaters will show its recently introduced PTS/PTU Series push through low intensity infrared tube heaters using positive pressure with its patent-pending Tube Integrity Safety System™ (TISS), designed to provide building owners with the ultimate in fire safety protection, says the company. With the TISS system, an insulated wire is placed above the reflector. If heat increases due to heat exchanger failure, the wire melts, the safety circuit is broken, and the gas controls shut down.
