AnyChem™ Vessels provide better Water Quality

Our Vessels are produced following the highest standard available for RO/UF/NF applications and are equipped with a thermoplastic PVC liner produced in accordance with the recommendations of the EU, The KTW, The DVGW and the Food and Drug Administration. The patented liner prevents microbiological growth on the inside walls of the vessels and the thickness of the liner protects the vessel from penetrating light.

Vessels can be kept clean easily which is mandatory for use with food products.

No monomers or fibers an leach from the resins of the fiberglass to pollute the water or food.
