RELCO History

RELCO, LLC has a strong history of providing quality products & services, and completing projects on-time and in-budget. Our growth and success has been achieved through continual focus on customer needs and designing customized process & control systems for them. Continual improvement and processing innovations have made our customers the low-cost processors of the industry.

Loren Corle started the business providing sanitary welding services which quickly evolved to sanitary project construction for dairy and food manufacturers. A Stainless steel fabrication shop was added to meet customized project needs.


With the merger of Doug Rolland’s company, Rolland Engineering, the pattern was set for the design and engineering structure that now provides the core of today’s business. Doug’s industry leading designs for flow processing systems continues to provide the basis for RELCO’s dedicated focus in this area. Building a skilled technical team of highly trained and motivated employees has provided the talent, and creativity to design innovated customer solutions.

In 1999 Kent Keller joined the RELCO team with the purchase of Whey Systems Inc. The KELLER™ Lactose Drying System is recognized around the world as the most efficient, low cost process to produce high quality edible lactose. The addition of KELLER™ Whey Systems added technical expertise in all phases of whey processing and has provided our customers a one-stop shop for total dairy process needs.

In 2007 RELCO acquired the assets of an engineering and stainless steel fabrication company in Drachten The Netherlands now known as RELCO wet & dry B. V. They provide similar services as RELCO to dairy and food plants in Europe and other related regions and expanded our technical engineering expertise for evaporation and drying. Today the RELCO team has the innovative skills and leadership to provide customized processing systems for dairy and food plants. From design, engineering, fabrication, automation and installation; RELCO products and services are recognized as leading the industry.

Our core values have been the underpinning of our growth and success, and will lead us into the future. We work as a team. We are customer focused. We are passionate about quality and safety. Our culture encourages innovation and creativity in all employees. We will not abandon our values.
