Challenger Pressure Tanks

Efficient and cost effective, Challenger tanks are designed with a patented controlled action CAD-2 diaphragm assembly. It features a chlorine resistant 100% Butyl diaphragm with a precision moulded copolymer polypropylene liner for superior air and water separation. The CAD-2 diaphragm assembly is clenched together with a positive lock internal clench ring which contains drawn down water in a pre-charged air atmosphere, thus providing separation between the diaphragm and tank wall. This “air buffer” design means few problems with condensation. Constructed with an FDA approved high grade butyl, the diaphragm assembly seals water in a true non-corrosive chamber.

This mode of construction provides valuable user benefits compared with standard pressure vessel where the pressurised water is contained in a butyl ‘bag’ which is constantly under stress and can be damaged if the air pressure in the vessel is not checked regularly and topped up as necessary.

Challenger vessels are virtually maintenance free the advanced design means that they cannot loose air pressure like conventional vessels. The exterior of the vessel has a two part polyurethane paint finish over an epoxy under coating to provide a high level of protection against corrosion particularly in damp atmospheres.

  • Also available with 2,3 & 4 way manifold.
