Our Story

In 1981, CLS was founded in Casper, Wyoming by Richard Gruner. The company’s core business was centered on long-term rentals and financial leases of air and gas compression equipment. Over the years, CLS’s focus grew to include not only renting and leasing equipment, but also the design, manufacturing and sales of air and gas compressors and other equipment and parts. 

In 1997, CLS was reincorporated, and Richard’s two sons, Ben and Daron, took over the company. 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 a company that supports all aspects of air and gas compression and equipment and part production and development. An upgrade in buildings allowed CLS to house an A.S.M.E. Code Vessel Shop, Skid Fabrication and Unit Assembly Line, Full-Service Machine Shop, and Sales, Engineering and Manufacturing Offices in the company’s 60,000 sq. ft. facilities. 

Today, CLS has facilities in Casper, Denver, Houston, and Gillette, Wyoming. Throughout our history, CLS has maintained an unwavering commitment to excellent equipment, service and customer relations.
