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.
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.
