Filtration technology

Terra® suction filters and strainer dryers

The process filter that combines several process steps

Terra® suction filters are pressure filters that can be sterilised. They work stepwise and allow the combination of different successive process steps in a closed system in a very confined space.

Terra® suction filters are suitable for processing easily filterable suspensions with a high solids content. Possible process steps: extraction, washing out, blowing out, steaming, vacuum and heating gas drying, dissolving and sublimation, as well as discharge of the solids.


  • High quality and performance reliability with gentle product processing
  • Can be extended with measuring, control and regulation systems, circulation heating or cooling, reaction tanks, heat exchangers, vacuum and compressed air units
  • Processing of toxic or oxygen-sensitive substances is possible
  • Highest demands on production safety are met
  • Convenient and variable operation thanks to manual control and computer-aided automation with video monitoring and process visualization
  • Production of the entire plant from a single source
  • 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
