Knappe Pressure Vessels

Knappe – Pressure Vessels

Knappe 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 vessel and the thickness of the liner protects the vessel from penetrating light.

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