Introducing TISSTM Tube Integrity Safety Shut-Off System
Space-Ray’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.
Vacuum
System
