Challenger tanks are ideally suited for a wide range of applications, including booster systems, thermal expansion, heating expansion, irrigation systems, and hydraulic hammer arresting.

Water Chamber, Patented Controlled Action Design: Efficient and cost effective, Challenger tanks are designed with a patented controlled action CAD-2 diaphragm assembly. It’s features a chlorine resistant 100% butyl diaphragm with a precision molded 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 drawdown water in a pre-charged air atmosphere, thus providing separation between the diaphragm and tank wall. This 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.

On the exterior, the almond colored two part polyurethane paint finish over an epoxy undercoating provides hundreds of hours of UV and salt spray protection.The air chamber is sealed with a fixed o-ring and closed cell foam and will provide many years of leak free and service free life. Challenger tanks are quality tested at several stages on the production line to insure the structural integrity of every tank. Challenger tanks are the best steel pressure vessels in the market today and represent the best value for the investment.
