Defender Series

Defender Features

  • The Defender stainless steel control box is water resistant and approved for high pressure wash down up to 3500 PSI.
  • Water resistant feature means easier maintenance and reduced man hours.
  • An energy efficient radiant heating system that saves fuel, reduces maintenance, and permits higher mounting.
  • Calorized aluminized steel emitter tubes for corrosion resistance and greater radiant output.
  • Can be used in a vented or indirect (unvented) mode. Available in either natural or propane gas models.
  • Tube lengths from 20 ft. to 60 ft. & BTU input ratings from 75,000 To 150,000 BTU/ Hr.
  • Optional Cold Air Stopper™ stops cold or hot air from entering the poultry house when the heaters are not in operation and helps to reduce sweating problems. (Not available on the 150,000 BTU/Hr. model).
  • Includes TISS™ (Tube Integrity Safety System) – Space-Ray’s patented, innovative safety system. In the unlikely event of a tube failure, TISS has been designed to automatically shut off the heater, providing greater safety and peace of mind. See detail below.
  • Heavy-duty cast iron burners for long life
  • Unique diagnostic monitory lights show when heater is operating and assists with fault diagnosis
  • The first 10′ of all model PCS tube heaters utilized calorized aluminized steel tubing (PDF). Calorized aluminized steel in all tube lengths is available as an option.

TISS

Tube Integrity Safety Shut-Off System

Space-Ray’s patented innovative safety feature for positive pressure radiant tube heaters is called the “Tube Integrity Safety System” (TISS™). The revolutionary TISS™ uses a simple principle to place an electrically insulated aluminum wire in tension above the reflector as shown above.

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.
