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.
It all started with industrial gases. Industrial Gases: a simple name for a complex technology that has been found in virtually all industries sectors, in research as in production. But then as now the use of this medium requires a lot of experience and circumspection, and a maximum sense of responsibility.
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-Kley. Today, around 20 highly qualified employees are working there. L + T GASETECHNIK is now LT GASETECHNIK.
Efficiency, the absolute, even unconditional compliance with all safety regulations, and focusing on technologically pioneering fields of application, are the basis of today’s corporate philosophy of LT GASETECHNIK. Facts reflecting the will to meet all market demands, today and in the future.
LT GASETECHNIK today operates in two business segments:
- Development and production gas related equipment and gas process plants, such as
- Standard gas mixers
- Gas mixing plants
- Gas dosing plants
- Control and measuring systems
- Development and production of fittings, with a focus on
- Safety Devices
- Central Gas Supply
for nearly all gas types and for use a wide range of technologically advanced, consistently demanding applications.
We can for example
- tap gases under control (cylinder manifolds and bundle systems, main pressure regulators for automatic or manual operation);
- purify gases (ﬁlters);
- regulate gas pressure (HP pressure regulators, dome-loaded pressure regulators,
- safeguard gases against ﬂashback and gas return (ﬂashback arresters, decomposition arresters, quick-action shut-off valves);
- analyse gases (sampled gas processing systems, analysers);
- mix gases (gas mixers, mixing systems);
- meter and feed gases (ﬂow meters, ball valves, pneumatic valves, pipe ﬂow
- and ﬁnally, feed them to the point of use under control (tapping points pressure
regulators and brackets, quick-action valves).
LT gas mixers are used to implement and optimise processes, particularly applications which demand the highest levels of quality and safety.
Hundreds – no, thousands – of LT gas mixers are have been delivered to the world for years, to some twenty countries in almost every corner of the globe.

|The “THERMOMAT” flashback arrestor is launched. The first LT gas mixer goes into operation|
Friedhelm Ludewig and Heinrich Tillmann found LUDEWIG + TILLMANN oHG in Dortmund-Barop. The company focusses on design and manufacturing of fittings and machines for the gas technology. One year later the company is renamed to LUDEWIG + TILLMANN Regel- und Sicherheitstechnik GAS – Schweißtechnik KG
