SJDT Steam-Jacketed Dispersion Tube

The
patented Armstrong SJDT (Steam-Jacketed Dispersion Tube) is an
all-stainless steel dispersion tube with the unique ability to accept
jacketing steam from atmospheric steam-generating humidifiers. The SJDT
uses a portion of the steam to “jacket” the entire length of the tube,
keeping the dispersion tube hot, even during periods of low demand. This
“jacketing” effect improves the quality of steam discharge and reduces
the chance for spitting or dripping in your air-handling system.

• All-stainless steel construction
• Simple installation
• Sizes from 1 to 10 feet (.3 to 3 meters) in length are available
