CNG Gas Dryer - STCNG24-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 at 150 PSI inlet pressure. Maximum allowable working pressure is 150 PSI at 500°F, with a minimum design metal temperature of -20°F at 150 PSI. The listing does not specify operating temperature range or outlet dewpoint capability, which you should request from the seller.

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

This dryer is designed for natural gas service and includes Xebec's Autodew system for CNG applications. The listing does not indicate whether it has been oxygen cleaned or what gases it has processed, so assume it is not suitable for oxygen service unless the seller confirms otherwise with documentation.

What should I inspect before putting it into service?

Verify the condition of the desiccant beds, which may need replacement if saturated or degraded during storage, and inspect all seals and valve seats for integrity. Check that the Autodew regeneration controls are functional and that the pressure vessel has current inspection documentation or can be hydrostatically tested to MAWP. Natural gas dryers can accumulate hydrocarbons or condensate in the beds, so confirm the unit's service history and consider whether internal cleaning is needed for your application.
