Sulphur dioxide (SO₂) is a key process gas in numerous industrial sectors – particularly in metal processing, the glass industry and food production. LT GASETECHNIK develops customized SO₂ gas mixing systems that meet the highest standards of safety, precision and reliability.
These systems not only ensure precise gas dosing and mixing, but also integrate extensive safety mechanisms – such as gas warning sensors, emergency stop functions, flushing processes and protected installation rooms – to minimize risks when handling the toxic gas.
Technology in detail
LT GASETECHNIK offers two proven system types:
-
Flow-regulated systems with mass flow controllers for a consistent gas supply
-
Pressure-regulated systems for constant supply at process-critical pressure levels
Both variants can be individually combined and automated – including visualization and control via HMI.
Application examples
-
Metal processing (magnesium die casting): SO₂ replaces the extremely climate-damaging SF₆ (GWP 23,500) and provides a safe protective atmosphere for the magnesium melt (GWP 0).
-
Food industry: As a preservative, SO₂ protects products such as wine from oxidation.
-
Glass industry: In flat glass production, SO₂ is used in precisely dosed quantities to supply annealing lehrs – such as in projects for Saint-Gobain or Gomelglass with a capacity of up to 1000 l/h.
Experience & competence
LT GASETECHNIK has been planning, manufacturing and supporting SO₂ systems worldwide for over 25 years – from compact cabinet solutions to complex container and distribution systems with up to six supply lines. Thomas Kubanek (formerly ASKI) has complemented the team with his expertise since 2024.
Together with its sister companies in the weyer group, LT offers comprehensive support: from process engineering design to approval planning.
