OUR STORY In 1998, CLS was reincorporated by brothers Ben and Daron Gruner. Along with a small group of dedicated employees, the Gruner brothers set out to change the compressor industry by integrating products, processes and services into the air and gas compression industry. In 2006, CLS expanded their footprint by adding a custom built fabrication shop. This new building houses an ASME code vessel shop, skid fabrication, unit assembly and a full service machine shop, in addition to drafting and engineering offices. CLS’ main office is located in Casper, WY in addition to Sales and Service Branches in Gillette, WY, Denver, CO and Houston, TX. Join the mailing list JOIN TODAY!
