CNG Gas Dryer - STCNG20-VZ1 Natural Gas Dryers, inlet 150 psi, flow 200-500 scfm

What pressure, flow and temperature is it rated for?

This unit is rated for 200-500 SCFM flow at 150 PSI inlet pressure. Maximum allowable working pressure is 150 PSI at 500°F, with minimum design metal temperature of -20°F at 150 PSI.

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

This dryer is designated for natural gas service based on the model designation and listing description. The listing does not specify oxygen cleaning status; if you need oxygen service or require documentation of cleaning procedures, contact the seller to verify compatibility and any cleaning certifications.

What should I inspect before putting it into service?

Verify the desiccant condition—if it has been exposed to atmosphere during storage it will need regeneration or replacement, and contaminated beds from upstream compressor carryover may require changeout. Inspect vessel externals for corrosion, check all pressure relief devices for current test dates, and confirm the Autodew control system powers up and that dewpoint sensors are reading properly. CNG dryers typically see hydrocarbon and particulate fouling, so plan to inspect inlet filters and consider opening the vessel to check for channeling or bed degradation if service history is unknown.
