    The history of LT GASETECHNIK

    We are really proud of our products and our services. We believe in us, and obviously do the many clients who trust us. And not just today, but from the beginning, exactly since January 1st, 1971

    L + T was established by engineers Friedhelm Ludewig and Heinrich Tillmann as „Ludewig & Tillmann Regel- und Sicherheitstechnik Gas” (that stands for “control and safety equipment gas“ with its headquarters in Dortmund-Barop. First there were designed and manufactured fittings and devices for the gas technology.

    Shortly after the foundation in 1971 a production hall with 1,300 square meters and an office building with 600 square meters was bulilt on a 5,000 square meters property in Dortmund-Marten. Today, around 25 highly qualified employees are working there. L + T GASETECHNIK is now LT GASETECHNIK.

    The case of a client who purchased one of our gas mixers (serial no. 4) in 1972 and proceeded to forget all about it for 22 years has become a company legend. Why? The system was not readjusted or otherwise serviced for 22 years, so it worked reliably for almost 200,000 hours without interruption.
    Or the case in which a 35-year-old dome pressure regulator is sent to us for maintenance and continues to do its job after the installation of the maintenance kit (to date only 5 years).
