High-precision manufacturing

Turned, wound, filled. In Senden.

Housings and cartridges are made on our CNC machines and winding lines. Every sealing face is true to a hundredth, every filling is weighed. Even for small runs from one piece.

From aquarium filter to filtration plant.

What you can rely on

Three things that have not changed here since 2002.

Tradition

A family business from Senden. We know our products down to the last seal, because we develop and build them ourselves.

Innovation

Our own TFC membranes, patented NewLine cartridges, remineralisation after osmosis and controllers we program ourselves.

Customer focus

Every project is matched to the requirement: from a single kitchen filter to an OEM series under your brand.

Know-how

From tap water to a clear glass in three stages.

This is how a reverse osmosis system works. Not as complicated as a filtration plant, but every stage has its reason.

Pre-treatmentSediment, sand, rust and particles are removed first. That extends the life of the membrane.
Reverse osmosis membraneLets water molecules through and holds back dissolved substances. Pore size 0.0001 to 0.001 micrometres.
RefinementActivated carbon for taste, minerals for vitalisation. Almost anything is possible here.

What passes is water. What stays behind goes down the drain.
