Gas mixing plant for a float glass line successfully supplied

Once again, a renowned flat glass manufacturer entrusted the supply of its new flat glass line with protective gas atmosphere and inert gas to LT GASETECHNIK.


Kabinburi Glass Industry awarded Float Glass Engineering (Euroglas) with the order to build a float glass line in Thailand. LT has earned a good reputation at Euroglas and in the glass industry as whole as a developer and manufacturer of equipment for technical gases. The experience gained in more than 45 years in this field also benefits a large number of customers in the fields of plant engineering, steel and copper processing, chemical industry, etc.


For the new float glass line near Bangkok the order comprises of a HNx gas mixing plant for protective gas atmosphere, mounted in a 40 feet container.

In the mechanical part of the container, the temperatures, pressures and amounts of the nitrogen and hydrogen gases are measured and controlled. The gas mixing plant provides the following redundantly:

  • Up to 1,600 Nm³/h of nitrogen for the bath,
  • Up to 400 Nm³/h as control and flushing medium;
  • Up to 1,600 Nm³/h as protective gas mixture made of nitrogen and hydrogen

The redundant plant control system and the partly redundant analysis system for the gas mixture are mounted in a separate gas-tight area.  Special features of the gas mixing plant are the cascade ratio control, guaranteed mixing accuracy, and the bumpless switchover.

At five places, the gases are analysed for moisture, oxygen content and hydrogen content. Process data, alarm signals and fault messages are displayed on the local control panel and are transferred to the process control system of the customer.



The whole system was completely designed and manufactured by LT Gasetechnik and was completely prefabricated at LT Gasetechnik production site. There it was accepted during a Factory Acceptance Test by the customer Float Glass Engineering. After delivery, the container only needs to be connected on site.

For all projects of this kind, LT is responsible for the complete process engineering, while taking all relevant safety aspects into account. LT also carries out plant design and detail engineering, manufacturing, installation and operators training.

A quote from the satisfied customer: „The gas mixing plant is super!“
