Description
CNG Gas Dryer - Regenerable Single Tower Natural Gas Dryer, inlet 5-120 psi, Flow rate up to 1876 scfm
Xebec STR30NGX-3 regenerable single tower natural gas dryer with AutoDew feature, professionally decommissioned from CNG station service. Flow capacity ranges from 336 scfm at 10 psi to 1876 scfm at 120 psi, with operating pressure rated 5-120 psig. Uses molecular sieve desiccant with integrated regeneration system including heater, blower, and condenser for closed-loop, heat-reactivated regeneration cycles.
Features
- Closed loop, operator-initiated heat reactivated regenerated cycles for reliable dryer regeneration control and shutdown
- AutoDew feature will signal when regeneration is required
Natural gas dryers remove water vapor prior to storing or using natural gas for a vehicle fuel. High water content can cause blockage of CNG in fueling systems and can contribute to corrosion in storage vessels and piping. The need for a dryer is determined by the water content of the incoming gas and the minimum ambient temperature.
The dryer uses molecular sieve adsorbent desiccants to remove water vapor to extremely low levels. After operating for a period of time, the dryer has removed so much moisture that it requires regeneration (heat evaporation process) or replacement of the desiccant. Dryers typically include a hygrometer, which identifies when the desiccant is completely saturated.
Regenerating Inlet Dryer is provided with a regeneration system that can periodically remove the water from the desiccant by itself. The additional equipment includes a heater, blower, and condenser.
This Dryer was professionally decommissioned from a CNG station owned and operated by a Local Distribution Gas Company (LDC) and managed by Clean Energy. There is a small dent at the top of the dryer we will fix that The dryer was fully functional with all of the required service and maintenance up to date prior to decomissioning. This can be aniIdeal solution for any CNG / RNG / Stranded gas project.

Questions buyers ask
What pressure, flow and temperature is it rated for?
Operating pressure is rated 5-120 psig. Flow capacity ranges from 336 scfm at 10 psi to 1876 scfm at 120 psi. Operating temperature range is not specified in the listing; ask the seller for the nameplate temperature ratings and confirm whether the unit includes insulation or requires environmental enclosure for your climate.
What gases is it compatible with, and has it been oxygen cleaned?
This unit was in CNG station service drying natural gas and is designed for natural gas, CNG, and RNG applications. It has not been oxygen cleaned and should not be considered oxygen-compatible without professional cleaning and verification. Molecular sieve dryers can generally handle most hydrocarbon gases, but prior natural gas service means this unit would require thorough cleaning and possibly desiccant replacement before use with other gas streams.
What should I inspect before putting it into service?
The listing notes a small dent at the top that will be repaired; confirm that repair is completed and verify vessel integrity with pressure testing per local code. Inspect the molecular sieve desiccant for contamination, clumping, or degradation—it may need replacement depending on how the unit was stored after decommissioning. Verify operation of the regeneration system components (heater, blower, condenser) and the AutoDew control system, and confirm all instrumentation including the hygrometer is functional and calibrated.
