About Us

Southwestern Corporation is an engineering and manufacturing company located and incorporated in the State of Colorado, United States of America.  Southwestern began in 1987 with the primary purpose of providing equipment and services to the Electric Power Generation and Cement Industries.  Today, Southwestern services over 50 major electric power companies in North America and around the world.

Southwestern's primary business is the design, manufacture and servicing of performance modifications and upgrades for coal pulverizers.  Our work force is experienced and familiar with the requirements and demands of our electric power generation and cement plant customers.  As a result, customer service is our top priority.

Southwestern's goal is to enhance mill efficiency resulting in improved boiler performance.  By controlling spillage in the mills, and enhancing fineness of the pulverized fuel, a reduction in emissions may also be obtained.

Southwestern has developed a long standing relationship with our suppliers who understand our requirements for quality materials and on-time deliveries.  This has resulted in a comprehensive system of supplier/partners to meet our needs, and yours.

On January 1, 2026, Southwestern Corporation became 100% employee owned and operated. We continue to employee the same great people you have come to know and trust over the years. Under new ownership, we look forward to growing our commitment to the Electric Power Generation and Cement Plant industries into the new year and beyond.

Service that is Second to none!
