Introducing TISS™ Tube Integrity Safety Shut-Off System
- SunStar’s patent pending innovative safety feature for positive pressure radiant tube heaters is called the “Tube Integrity Safety System” (TISS™).
- In the unlikely event of a tube failure, TISS™ has been designed to automatically shut off the heater. The revolutionary TISS™ uses a simple principle to place an electrically insulated aluminum wire in tension above the reflector. Low voltage is then continuously passed along the wire in line with the gas control circuit. If heat levels increase due to heat exchanger failure, the wire melts and the safety circuit is broken, breaking the 24 volt circuit and shutting down the heater.
- You may never know it is there, but it provides peace of mind.
