CleanFlow™ Instrument Grade Natural Gas Conditioning Systems

Brand: Welker, Inc
Convert on-site natural gas into a convenient and cost-effective power source for your pneumatic instruments.
  • CleanFlow™ Basic (Contaminant¹ and Liquid² Removal)
    • An active Welker Filter Dryer and Welker Liquid Dump
    • OR, More than one active Welker Filter or Filter Dryer
  • CleanFlow™ (Contaminant¹ and Liquid² Removal With Pressure Regulation)
    • One active Welker Filter Dryer with pressure regulation; optional Welker Liquid Dump; optional heater
    • OR, One or more active Welker Filter Dryers with pressure regulation; optional heater
  • CleanFlow™ Plus (Contaminant¹ and Liquid² Removal With Pressure Regulation and Automatic Backup Filtration)
    • Primary and backup Welker Filter Dryers with pressure regulation; optional Welker Liquid Dump; optional heater
Superior Instrument Protection

At the heart of all CleanFlow™ Instrument Grade Natural Gas Systems is the industry-recognized Welker Filter Dryer, which effectively removes the contaminants natural gas picks up as it flows through pipelines. For wet gas streams, a Welker Liquid Dump separates aerosols and free liquids prior to filtration, increasing the interval between cartridge replacements. A heater provides additional freeze protection for locations with low ambient temperatures or where a significant reduction in pressure is necessary.

Instrument-Ready Pneumatics

Regardless of configuration, CleanFlow™ and CleanFlow™ Plus systems come equipped with a regulator for each filter to effectively reduce pipeline pressure to a functional range. 

In CleanFlow™ Plus systems, the incoming natural gas automatically flows to the backup filter when the primary filter cartridge needs to be replaced, allowing field technicians to conveniently schedule cartridge changes.

¹ Contaminants include such things as dirt, pipeline debris, rust, and odorant that can contribute to clogging and damage to sensitive equipment.
² Liquids include such things as excess water content and liquid hydrocarbons.
Features
  • Industry-recognized Welker Filter Dryer
  • Integrated backup filter and regulator system
  • Welker Automatic Liquid Dump (ALD) or Manual Liquid Dump (MLD)
  • Optional catalytic heater heats pipeline gas to desired temperature
Benefits
  • Use pipeline gas to supply pneumatic instruments  
  • Protects sensitive equipment from damage caused by liquids and contaminants    
  • Backup filter and regulator automatically activate when primary filter and/or regulator require maintenance    
  • Effectively reduce pipeline pressure to functional range    
  • Prevent service interruptions due to freezing
