Where It's Used

Applications & Industries

Aggressive media gas

All-stainless CU construction for sterile gas filtration in corrosive or aggressive process environments.

Brewery & fermentation

Sterile CO₂, nitrogen and process air for fermentation vessels and bright beer tanks.

Dairy & beverage

Sterile gas for UHT, filler headspace and aseptic lines where full stainless contact surfaces are required.

High-temperature SIP

Min. 100 in-line and min. 200 autoclave cycles guaranteed (in-line, slow-speed saturated steam: 121 °C/30 min, 131 °C/20 min, 141 °C/10 min); operating temperature −20 … +200 °C.

F&B sterile gas

All-stainless sterile process gas wherever nano-retention and aggressive media compatibility are required.
