As diverse as your applications
Compressed air is omnipresent in industry and has become indispensable in many applications - be it in chemical/ petrochemical process technology, electronics and semiconductor production, the food and beverage industry, the textile industry, medical technology and many other areas.
Textile industry
The textile industry, such as yarn and fabric production, dyeing, weaving, winding or spinning, requires oil-free process air that protects the production facilities from damage and ensures the high product quality of the end product.
Medical and pharmaceutical technology
In the sensitive areas of medical and pharmaceutical technology, a number of applications have to be equipped with completely reliable and exceptionally clean, purified medical process air. An uninterrupted supply of compressed air must be guaranteed in every situation.
Electrical and semiconductor industry
The following applies to the process requirements: The compressed air must be clean and dry; downtimes due to contaminated systems or entire product batches must be avoided at all costs. High reliability and availability are a must.
Chemical and petrochemical industry
Uninterrupted continuous operation in chemical plants requires a continuous supply of compressed air. Our powerful compressors ensure reliable operation.
The service life of the packages is an important aspect when the plants are used continuously.
Oil and gas industry
Heat, electricity and petrol are the products in this branch. Compressed air plays a central role in the production. Pneumatic applications in the oil and gas industry are challenging and require the highest level of safety. The control system, instrument or buffer air requires 100 % oil-free operation.
Food and beverages
In production processes in the food and beverage industry, such as fermentation, the transport of powders, cleaning, filling, cooling, packing and packaging of food, contamination by oil must be ruled out with regard to the quality, odour and grade of the end product; any risks lead to considerable costs due to production losses, so that the protection of the end product is crucial.
