Our history On the way to becoming Number One

With visionary entrepreneurial spirit and an excellent instinct for the growing importance of electronics in industrial production, Wilfried Schmitz established a company in 1997 that sold sensors, electronic cooling solutions and rotary controls, therefore laying the foundations for the success of CTX Thermal Solutions GmbH. Today, with our uniquely comprehensive product line, we are among the leading suppliers of cooling solutions in Europe and can look back on a quarter century of success.
