PNEUMATECH HEATLESS REGENERATIVE AIR DRYER with 2 150 PSI Silvan Pneumatic Tanks

What pressure, flow and temperature is it rated for?

This unit is rated for 2600 SCFM at 150 PSIG maximum pressure with a purge pressure of 55 PSIG. The included Silvan tanks are rated for 150 PSI at 450°F maximum allowable working pressure and -20°F minimum design metal temperature. Heatless dryers typically operate with inlet air temperature limits around 100-120°F; ask the seller for the original nameplate inlet temperature rating.

What gases is it compatible with, and has it been oxygen cleaned?

This is an air dryer designed for compressed air service. The listing does not state whether it has been oxygen cleaned or used in oxygen service. For any oxygen application, you must confirm service history with the seller and have the unit professionally cleaned and certified before use, as hydrocarbon contamination presents severe explosion risk.

What should I inspect before putting it into service?

Verify desiccant condition in both towers—check for dust, beading breakdown, and proper fill level (825 lbs per tower of AA2/5 and MC 4A as specified). Test all switching valves, purge valves, and check valves for proper seating and cycle timing, as stuck or leaking valves are the most common failure mode in heatless dryers. Inspect both Silvan tanks for current hydrostatic test certification and condition of all pressure relief devices. Confirm the 115V single-phase control circuit is complete and functional, and verify inlet filtration is adequate to prevent desiccant contamination.
