CNG Gas Dryer - STCNG14 Natural Gas Dryers, inlet 150 psi, flow 200-500 scfm

What pressure, flow and temperature is it rated for?

This unit is rated for 150 PSIG inlet pressure with a flow range of 200-500 scfm. The MAWP is 150 PSI at 500°F and the MDMT is -20°F at 150 PSI.

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

This dryer is designed for natural gas in CNG applications. The listing does not indicate whether it has been oxygen cleaned; ask the seller for service history if oxygen service is intended, as hydrocarbon contamination typically disqualifies equipment for oxygen use without specialized cleaning and certification.

What should I inspect before putting it into service?

Inspect the desiccant condition and verify the Autodew control is functioning, as moisture breakthrough from exhausted or contaminated beds is the most common failure mode in these dryers. Check all pressure vessel welds and fittings for corrosion or damage, verify pressure relief devices are in test date, and confirm inlet filtration was adequate during previous service to avoid bed contamination. Request maintenance records and the date of last desiccant change from the seller.
