BHS-Sonthofen has decades of experience and comprehensive process engineering know-how in the manufacture of plastic intermediates. Our rotary pressure filters (type RPF) and indexing belt filters (type BF) offer you high throughput rates and process reliability over the long term. The total operating costs are very low, despite achieving exceptional product quality.
Whether you are processing polyamides, terephthalic acid (PTA), aramids, polymers, bisphenol or other plastic intermediate products: Continuously operating high-performance filters deliver high product quality due to the excellent washout quality they provide. The filters have a long service life, are built for robust use and ensure economical plant operation thanks to the low maintenance and energy costs they incur. Operating temperatures of up to 160 °C with the rotary pressure filter and filter surfaces of up to 100 square meters with the indexing belt filter go a long way toward ensuring efficient production.
BHS-Sonthofen leads the market in this field. A large share of the global production of terephthalic acid, better known as PTA (purified terephthalic acid), passes through BHS filters. Our high-performance filters are used for this purpose across the world.
