ALD

Automatic liquid removal for wet gas and instrument supply protection

The Welker ALD Automatic Liquid Dump is designed to separate aerosols and free liquids from wet natural gas or instrument air supply streams and automatically drain collected liquids with minimal pressure drop. Ideal for remote locations or CleanFlow™ systems upstream of pneumatic instruments and actuated equipment, the ALD uses an internal coalescer, automatic draining, and adjustable float level to help protect downstream instrumentation from liquid damage and contamination. By reducing liquid buildup and limiting technician intervention, the ALD supports reliable natural gas conditioning and instrument supply performance.

Where to Use

Remote Liquid Removal

Anywhere liquid slugs, aerosols, or free liquids accumulate and need automatic removal.

CleanFlow™ Systems

Upstream of pneumatic instruments or pneumatically actuated equipment as part of a CleanFlow™ system.

Orifice Measurement Protection

Applications where reducing liquid buildup helps protect measurement reliability.

Resources

ALD IOM
