Medical engineering
  • Sterilization of surgical instruments, textiles and beds (steam- and gas sterilization)
Plastics industry
  • Extruder degasification
Food industry / Pharmaceutical industry
  • Degasification of toothpaste, cremes, lotions, marzipan etc.
  • Vacuum cooking of fruits, vegetables, pulps and mush
  • Thickening and crystallisation of sugar under vacuum
  • Chemical industry
