Tube Integrity Safety Shut-Off System (TISS™)

This series incorporates the innovative Tube Integrity Safety System (TISS™), a patent-pending safety feature for positive pressure radiant tube heaters. An electrically insulated aluminum wire is tensioned above the reflector and monitored by a low-voltage circuit. If abnormal tube temperatures occur, the wire melts, opening the safety circuit and shutting down the heater for added protection and peace of mind.

Built for demanding environments

Tough Guy option – all aluminized steel radiant tubes
