1 DualVesselFully Automatic RegenerationNGV fuel GasDryersNG-EVPSB INDUSTRIES 9001:2008 CERTIFIEDMADE IN THE General Air Division(formerly a divisionof Zurn Industries) specializes in compressed air,gas, and liquid dehydration/purificationtechnologies and offers a diverse lineof productapplications. Our packaged systems from thesmallest to the largest applications removemoisture and contaminants from process Natural Gas dryer Fully AutomaticRegenerationPSB type NG-EVis an ideal systemfordryingmediumto largevolumes of naturalgas for stations with continuoususe. Eachunit is conservatively sized to removemoisture from gas upstream the natural gascompressor(s).Continuous operation is assumed with thedual vessel design.
2 Whileonevessel is onstream drying, the other vessel isregenerating or in standby mode and readyto be placed back on stream. DDP Digital Dew Point Meter is providedto indicate the effluent dew point,confirming s standard packageincludes factory fitpre filter for removing dirt/aerosols andafterfilter for removing desiccant Typical Options: Three (3) valve block and dryer bypasspiping arrangement. CWP (Cold Weather Package) is availablefor Regeneration in freezing heat tracing and insulation oncondensate sump/drain lines and includesPLC control panel heater. PSVVent Stack Assembly. Includes reliefvalve exit piping and stack vent to 10 vessel PSV is included asstandard.
