In 1971 the owners of Treanor Equipment Company, a Caterpillar dealership headquartered in Odessa, Texas, founded Compressor Systems, Inc. to enhance the sales of gas engines to the compression industry. The original owners included two members of the Treanor family and Johnny Warren, then CSI’s General Manager and a minority shareholder. Mr. Warren and his family bought out the other stockholders in 1975 and have owned a majority of the company since that time.

Today, Warren Equipment Company operates Compressor Systems, Inc., Ignitions Systems & Control, Pump Systems International, and Warren CAT. These companies operate in fourteen states, two foreign countries, and have approximately 2100 employees and supply products to clients throughout the United States and various international markets. Our commitment is to exceed the needs and expectations of our customers by providing products and services that are an excellent value, perfect for their purpose, delivered on time and with reliable operation. Through keeping this commitment and building long-term relationships, we have achieved customer and employee satisfaction.
