Dual Vessel
Manual Regeneration

NG-SRD is the dual vessel version allowing for continuous drying. While one vessel is drying the other can be manually regenerated without interrupting the drying flow.

When the desiccant vessel has reached maximum drying capacity, it can be regenerated manually with the operator initiated, on skid regeneration package. A "DDP" Digital Dew Point Meter is provided to indicate the effluent dew point, confirming performance and need for regeneration. PSB's standard package includes factory fit pre filter for removing dirt / aerosols and after filter for removing desiccant dust.

Dryer Design Features:

Dual vessel design manufactured and stamped per ASME code Section VIII. Alternatives available.
Piping designed per ASME B31.3
NEMA / NEC electrical construction standard
Closed-loop regeneration of the molecular sieve adsorbent
Three valve block and bypass piping arrangement for
isolation of the dryer
Pre filter and after filter complete with differential pressure indicators
Insulated adsorber vessel and electric heater for heat conservation 
Incoloy sheath, low watt density flanged immersion type electric heater

(1) Capacity multiplier for moisture contents other than 7 Ib. HO/MMSCF for type SV, SR and SRD models.

Example: Capacity of model NG-SR-6.5-2 with actual inlet natural gas with 10 lb. H2O/MMSCF

Multiply model # (which is dryer capacity) 6.5 MMSCF x 0.7 (multiplier) = 4.55 MMSCF new capacity
