CNG Gas Dryer - Regenerable Single Tower Natural Gas Dryer, inlet 5-120 psi, Flo

What pressure, flow and temperature is it rated for?

This unit operates at 5-120 psig with flow capacity of 336 scfm at 10 psi, 1561 scfm at 100 psi, and 1876 scfm at 120 psi. The system relief valve is set at 150 psig. Operating temperature range is not specified in the listing; you'll need to confirm this with the seller along with any inlet dew point or temperature limitations that may affect stated capacity.

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

This unit was designed and configured for natural gas service, as indicated by the model designation and listing title. There is no indication it has been oxygen cleaned or certified for oxygen service. Regenerable desiccant dryers can generally handle various hydrocarbon gases, but converting between service types requires complete purging, proper desiccant selection for the new gas, and compliance with applicable codes—oxygen service in particular demands specialized cleaning and materials verification that this listing does not document.

What should I inspect before putting it into service?

Inspect the desiccant bed for contamination, clumping, or dust carryover, and confirm the AutoDew controls and switching valves cycle properly through regeneration. Check vessel exterior and all flanged joints for corrosion, verify the relief valve is in test date, and confirm electrical components match the 280 Vac/3-ph/60 Hz requirement. Single-tower regenerable dryers rely on the regeneration cycle to maintain performance, so any control or heater failures will result in immediate outlet dew point degradation.
