PSB - Model NG-SRD -Dual Vessel Manual Regeneration Fuel Gas Dryers

When the initial charge of desiccant hasreached maximum drying capacity, it canberegeneratedmanuallywith the operatorinitiated,external regeneration package.A“DDP” Digital Dew Point Meter isprovided to indicate the effluent dewpoint, confirming performance,and needfor regeneration.PSB’s standard packageincludes factory fitpre filter for removingdirt/aerosols andafter filter for removingdesiccant dust

• CWP (Cold Weather Package) isavailable for regeneration in freezingconditions. Includes heat tracing andinsulation on condensate sump / drainlinesand includesPLC control panelheater.
• PSV Vent StackAssembly.Includesrelief valve exit piping and stack vent to10foot elevation. Ships separate due toheight.DryervesselPSVis included asstandard.
• 200 MWP is standard.Typicalpressuredryer options are 300, 500, 635, 875,1100, 1250, and 1525MWP-PSIG
