When implementing the topic of “welding gas mixtures”, the highest accuracy may be important for quality and/or cost reasons. This is where the gas mixers from LT GASETECHNIK show their special strength. Projektbeispiel “Schweißgasgemische” Panel production plants and profile welding with gantry welding machines use gas mixtures of Ar, CO2, and Ar, CO2,…

As a result of the energy transition, hydrogen is also becoming increasingly interesting as a fuel gas. Hydrogen/oxygen gas mixtures have been used in flame polishing of high-quality glass containers (crucibles, flacons, etc.) since a long time. LT has experience with engineering, safety design, production including control system, commissioning of systems for the supply…

Transportable gas analyzers from LT GASETECHNIK can also be equipped with several measuring cells for mobile use at the customer’s request. For example with a thermal conductivity detector (short TCD with the typical use for forming gases, i.e. H2 in N2) and near infrared sensor (short NDIR with the typical use of welding gas…

Gas mixtures of natural gas and hydrogen are very a hot topic. LT GASETECHNIK has been manufacturing plants for natural gas mixtures for decades. Highly precise gas mixing systemscan reproducibly generate the required gas mixture composition with adapted measurement, control and analysis systems. These gas mixers are often used for test stands in test centers,…

The reason for this significant saving potential is a question of arithmetic: Here is an example: In this example the product quality will fluctuate and get worse if there are less than 5% H2 in N2 in the mixed shield gas.A conventional gas mixer has an accuracy of +/- 2% abs. that means for safety’s…

The article in the February 2021 issue of APCJ describes the possibilities to meet the requirements of lean air system operators for quality, safety and availability. The aim is always to reliably maintain the specified oxygen concentration in the gas mixture to achieve defined product quality safely. The article describes various suitable technologies, including…

Explosive atmospheres in vessels are for example created by dust (ground products) or by degassing (production or storage of flammable substances). Covering with pure nitrogen can be undesirable. Either because the “lower explosion limit” can also be safely adhered to with a residual oxygen content or because a residual oxygen content is necessary in…

LT GASETECHNIK has once again manufactured and supplied two control and safety lines for burner supply on a preheater tower of a German cement rotary kiln (gas pressure control systems). The gas is used for afterburning nitrogen oxides (NOx) and carbon monoxide (CO) with propane/oxygen. Propane control and safety system: Performance: 3…30 Nm³/h Outlet pressure…
