Prevention of odour nuisance and corrosion in

With oxygen the chemistry is right

Oxygen optimises the production of sulphur and sulphuric acid

Quality and environment hand in hand

Industrial gases optimise paper production

Water enhancement

Carbon dioxide neutralises wastewater in the construction industry – ecologically and economically

Less oxygen, more safety and quality

Targeted protection during production, storage and transportation, through inerting

Cold solvent recovery

DuoCondex uses cryocondensation to optimise waste gas purification

High Efficiency through Low Temperatures

Cryocontrol – optimizes synthesis processes in pharmaceutics and fine chemistry

Gases improve drinking water quality

Water is most important and strictly controlled foodstuff

Effective cleaning of industrial waste water


Weak acid, strong effect

Carbon dioxide neutralises alkaline wastewater in an environmentally friendly and cost-effective way.
