Über L+T GASETECHNIK Klöpper-Waldmann GmbH & Co. KG

Development and manufacture of high-performance gas technology systems, gas mixers, series-produced fittings and control solutions. Production of small series and customer-specific systems with the highest standards of engineering, safety and quality. Complex technical requirements are both an incentive and an incentive for us – in other words beyond standards.

We supply systems and valves for a wide range of industries and industrial applications for gas engineering applications with flammable or non-flammable, corrosive or toxic technical gases. Our range of products extends from serially produced valves and fittings through standard systems to individually planned large-scale gas supply systems as control systems for pressure and/or volume flow or as gas mixing systems. L+T GASETECHNIK Klöpper-Waldmann GmbH & Co. KG plans and manufactures, including associated control and analysis technology – from the concept to commissioning – all from one source.

Natural Gas Shortage

LT GASETECHNIK is your partner around the topic of natural gas substitution by shutdown or embargo in the Russia/Ukraine conflict. We are currently receiving an extremely large number of inquiries on the subject and are available for advice and support. Often the gas mixture of propane with air is sought, but also (supplementary or alternative) CNG, LPG or butane with air.

Together with our partners, we supply the complete solution from a single source, from consulting, approval, tank, evaporator, unloading station, gas mixing plant, to safety technology and feed-in.

free of charge app for gas mix calculation

The app supports the setting of the gas mixture for LT gas mixers in order to calculate volume flows and percentages for two or three gases. For gas mixers for two gases, only two out of five possible values (total quantity, carrier gas quantity, carrier gas proportion, proportioning gas quantity, proportioning gas proportion) have to be specified. With three gases, there are at least three values. After clicking on the “Gemisch berechnen” button, the results are displayed, including the values previously entered by the user. The volume flow can thus be read directly and precisely adjusted on the metering valves and the desired gas mixture is generated precisely and comprehensibly.
