Filtration technology

Wega® filter dryers

Different processes combined in one system

Wega® filter dryers are further developed pressure strainers with an integrated agitator, designed as vacuum dryers with a heatable or coolable container and filter bottom.

Application:
Wega® filter dryers can be swivelled into various working positions for reaction, precipitation, crystallization, filtration, washing, drying and discharge.

Advantages:

  • Ideally suited for the production of sterile pharmaceuticals in GMP-compliant batch operation
  • Closed system without product transport between the different process stages
  • Personnel and the environment are not exposed to toxic substances and solvents
  • Short drying times and uniform product quality due to intensive mixing and sufficiently dimensioned heating surfaces including a heated stirring element
  • Only high-quality materials such as austenitic stainless steel (1.4307, 1.4571, ...), fully austenitic stainless steel (1.4539, 1.4828, ...), duplex (1.4462, 1.4410, …), NiCrFeMo alloys with Ni > 40% (Inconel, Hastelloy, ...) are used

Technical details:
Wega® filter dryers are built in two basic versions, depending on their field of application.

  • Chemical version: robust functional design for high-quality products
  • Pharmaceutical version: the enhanced version for the production of substances with the highest purity requirements
