Mobile Glass Nutsche Filters

ATR-ASAHI Nutsche filters are known for their effective filtration, leak-proof mounting and easy adjustment. Nutsche filters come upto 300 liter capacity in Non-Jacketed construction and upto 100 liter capacity in double wall, jacketed construction. The design pressure is less than 2bar G. ASAHI filters are known for the effective filtration-maximised filtering efficiency. It has unique filter housing which prevents leakage and provide Leak-proof mounting system. Filters are having easy adjustment and centering system, since the systems are engineered with guided mounting system for ease of use. The equipment also comes with convenient handling cart. The filters can be fully customized and the nozzle orientation can be changed suiting the user’s needs. E.g are Stirrer handle, Feed pipe, Spray nozzle. Filter housing consist of Leak-proof mounting system resulting in high sealing performance. Filter is made of PEEK, PTFE, PP. The mesh size : 1-5,100 micro meter. The Stirring apparatus consists of locking, multi-directional stirring devise which maintains uniform cake (upto 150 mm).

Filter reactor

ATR-ASAHI make filter reactors are characterized with most efficient easy plug and play design. Some of the key features of the filter reactor are :-

  1. Easy scale-up.
  2. All in one unit.
  3. Variety of vessel options.
  4. Wide temperature range.
  5. Time and cost saving.
  6. Full Jacket design
  7. Minimized dead space.
  8. Easily removable filter house.
  9. Compact design.
  10. Rigid inlet/outlet.
  11. Complete package.

The filter reactor comes with the suitable design providing the allowance for easy scale-up meaning 1L reaction vessel can be easily replaced with 2L/3L/5L reaction vessel in the same setup/arrangement. The filter reactor comes with various vessel options- Triple wall with Ring Baffle, triple wall without ring baffle, Double wall with ring baffle, double wall without ring baffle. Our filter reactor is a all in one unit since the reaction and filtration takes place in the same filter unit. The filter reactor is for wide temperature range from -90 deg C to 200 deg c providing a temperature delta of 110 deg C.The full jacketed design convers the entire vessel area. The dead space is minimized and filter housing is with easily removable design.
