Flood Control

Analyzer getting slugged by liquids? Put an end to costly damage and operational shutdowns—install a Welker ALS-4 Analyzer Liquid Shutoff upstream of your gas chromatograph. Gas flows freely through the ALS-4 for online sampling but shuts off flow to your analytical device in the presence of liquids.

Cost-Effective Protection

Gas chromatographs are highly sensitive pieces of equipment. Liquids in gas samples can contaminate and damage analyzer columns, resulting in expensive repairs and interrupting normal operations. Compared to these costs, the purchase of an ALS-4 is literally a small price to pay.

Tough as Nails

Corrosion Resistant Material

Natural gas is a variable mixture potentially containing nonhydrocarbons, such as hydrogen sulfide or water. For long-lasting protection you can trust, Welker manufactures the ALS-4 using materials that stay strong in the presence of corrosive elements.

Back to Basics

Straight Forward Maintenance

Flow to your analyzer shut off? Backflushing the ALS-4 with dry nitrogen or helium pushes liquids back to the pipeline so you can resume normal operation.

Time for routine maintenance? Get your online sampling back up and running quickly thanks to an uncomplicated design requiring only basic hand tools.
