PPM Grade Dual Column Inert Gas Purifier with Regeneration Heater ( Removing O2 & H2O to PPM ) - GPH-DHDO


Please email for lead time
Item Number: GPH-DHDO
GPH-DHDO connects two gas purifiers ( one for de-oxygen and another for de-humidity ) together by 1/4'' stainless steel pipe and two valves and ready to install to any MTI gas mixing system. It reduces gaseous impurities to sub-ppm levels at room temperature operation. It removes H2O, O2, CO, CO2, H2 and NMCH's to <0.1 ppm from any  99.9% purity inert gas (Nitrogen, Argon, Helium, Krypton, Neon and Xenon) and H2O, O2and CO2 from Hydrogen. What is more, it has the buit-in heater which can be heated to 300C to easily regenerate the de-oxygen and dehydration chemical in the unit for long term use.
 
Features:
  • Input gas purity requirement: < 1000 ppm  ( 99.9%)
  • Output: Removal of impurities to < 0.1 ppm   ( O2 ≤ 0.1ppm  H2O ≤ -76℃ in dew point,  ( Please click here to convert humidity unit )
  • 304L SS (<10 Ra EP) vessel
  • Easy to regenerate
  • Digital temperature controller and Gas flow meter control are built in
  • Purification capacity up to 80L inert gas after regeneration
  • The unit should be regenerated at 270 oC ( using 5N purity gas of 95%N2+5%H2)
