Sefiltec – Filtration Technology Website with Craft CMS

Sefiltec AG from Höri near Zurich is Switzerland's address for separation and filtration technology: founded in 1993 as a one-man company, the business celebrated its thirtieth anniversary in 2023 and today employs almost twenty people. Under the principle of "engineering and production under one roof", Sefiltec designs and manufactures customer-specific filter housings according to the pressure equipment directive – with over a thousand square metres of warehouse space and 24-hour delivery readiness within Switzerland.

The offering is deep and technical: thirteen product categories from bag and cartridge filter housings to sterile filters, membranes, belt filter systems and coolant treatment, used in ten industries from pharmaceuticals and biotechnology to water treatment. We built the website for this structure with Craft CMS: products and industries are modelled as independent content types that reference each other – and are maintained by the Sefiltec team itself.

The product pages are tailored to engineers and buyers: materials, sizes, connections, surfaces and special versions are presented as clearly organised specifications – from stainless steel 1.4404 housings to ETFE coatings. The industry pages translate the same range into the language of the application, from microelectronics to the beverage industry. The entire site is bilingual in German and English.

Visually, the website carries the Sefiltec colour world of rich green and dark violet: large headers, cut-out product photography on green stages and icon tiles for the industries. The claim "competence in filtration" sits permanently in the header – and the website delivers on it with structure and depth.

The result is a digital catalogue with character: technically precise, bilingual and built so that new products and industries can be added in minutes.
