Dual Vessel Fully
Automatic Regeneration

PSB type NG-EV is an ideal system for drying natural gas needing 24/7 operation. Each unit is conservatively sized to remove moisture from gas.

Continuous operation is assured with automatic switching valves and dual vessels. While one vessel is on stream drying, the other vessel is regenerating or in standby mode and will automatically be placed back on stream.

"DDP" Digital Dew Point Meter is provided to indicate the effluent dew point, confirming performance.

PSB's standard package includes factory fit prefilter for removing dirt/aerosols and after filter for removing desiccant dust.
