With a chlorine resistant 100% butyl diaphragm, incorporating a precision molded polypropylene liner, the Challenger™ Series tanks offer superior air and water separation.  The CAD-2 diaphragm and liner assembly containing drawdown water are sealed together with a positive lock internal clench ring.  An ‘air buffer’ prevents the water chamber from being in contact with the tank wall in order to minimize condensation issues.

Constructed with FDA compliant high-grade butyl and polypropylene, the diaphragm assembly seals water in a true non-corrosive chamber.  The air chamber is sealed with a fixed O-ring and closed cell foam which will ensure years of leak free operation and eliminate the need for regular servicing.

The exterior comprises a two-part polyurethane paint finish over an epoxy undercoating which guarantees hundreds of hours of UV and salt spray protection.

As with all GWS products Challenger™ tanks are quality tested throughout the production process to ensure their structural integrity. Maintenance free, these tanks are the best steel pressure vessels on the market today, and represent a cost effective solution.
