Gas Purification and Drying Unit

This drying unit provides adequate removal of contaminating organic materials commonly found in oxy-hydrogen gas supplies for microtorches which, upon combustion, deposit on flame tips reducing flame efficiency.

The purification and drying unit comprises a commercial gas drying tower 1 packed from bottom to top with the following materials: glass wool 2, activated charcoal 3 (6-14 mesh), glass wool 2, molecular sieve 4 (Grade 521, Type 5A, 4- 8 mesh glass beads-Fisher Scientific #M521), glass wool 2, anhydrous calcium sulfate 5, or DRIERITE* #2, and felt filter pads 6. The oxy-hydrogen fuel supply is provided by a catalytic electrolytic water dissociator, not shown, and after passing through the filter unit is passed to the microtorch tip for combustion. * Trademark of W. A. Hammond Drierite Comp.
