– Vessel heated on all surfaces to optimize drying efficiency

– Precise construction to the millimeter

– Sealing and drive system according to your choice

– Commissioning at your facilities

– Machine, partly completed machinery, and ATEX certification

Manufacturing of Nutsch (Nutsche) Filters and Retrofits

The Nutsch filter—also known as a Nutsche in German terminology—is a

solid-liquid filtration equipment essential for fine chemical processes and

pharmaceutical manufacturing. Meili Technology has been custom-manufacturing it since its

Bex workshop and also offers services to bring your existing filters up to code,

– Filter base with removable elements

– Option to heat the vessel and the agitator

– Complete compliance retrofitting of your legacy pressure filters of all brands

– Commissioning at your facilities

– Certification for machines, partly completed machinery, and ATEX

– Available materials: standard 316L stainless steel, Hastelloy C-22 for aggressive solvents,

based on your process requirements.

Mixer manufacturing

Meili Technology manufactures custom-made industrial mixers tailored to your needs

for mixing powders, solids, or viscous products. Stainless steel spiral mixer

or nickel alloys, depending on the product with which it comes into contact.
