Since 1978, Chemtex has been dedicated to helping customers maintain clean and efficient heating, cooling, wastewater and process systems. We are one of the largest independently owned water treatment companies. We believe in a Simple, Focused, Driven approach.


With our Simple Focused and Driven approach, we make these 3 promises:

  1. To make the process of working with us as simple as possible.
  2. To focus on and understand our client’s needs and exceed their expectations.
  3. To be driven to provide the best experience for our customers. Every time.


Our ISO 9001:2015-certified main production facility and technical laboratory is in Lakeville, Minnesota. We also have production facilities in Roanoke, Virginia and San Juan, Puerto Rico and over 30 sales offices to serve our customers throughout the United States.


We’re a growing company with a big heart. Our focused, personal scale enables us to pivot quickly in response to client needs and changes in the industry/economy. We work hard to compete with the larger competitors, we’re constantly learning and evolving our offerings.


Gary Glenna and Lynn Buri founded International Chemtex in 1978. They recognized that mechanical companies depended on top-notch water treatment assistance to deliver their services safely and effectively. Chemtex was determined to provide water treatment services equal to those of their large competitors, but with the responsiveness of a small focused, family business.


As water treatment standards have evolved over the last four decades, we’ve stayed on top of the new technologies and increasingly sophisticated equipment. This helps every customer maintain a clean system, save energy and water, lower maintenance expenses, and keep building occupants healthy. We try to make it simple for them at every turn.


Solution-oriented services are at the heart of the Chemtex philosophy. As our clients shift toward greater automation and decreased staffing levels, they rely on our expertise more than ever.

What I do is help everyone to the best of my ability. Helping others is what I like the most about my role. The safety stuff is also pretty interesting. There’s always something new to learn.

Outside of work, I enjoy playing video games and volleyball with the occasional brewery visit thrown in there. Of course I love spending time with my family as well.
