Challenger™ tanks are designed with an innovative patented CAD-2 controlled diaphragm action technology. 100% chlorine resistant butyl membrane with polypropylene copolymer coating. Membrane mounting is done with an internal retention block ring that facilitates the separation of water into a pre-charged atmosphere, providing a separation between the membrane and the tank wall in an anti-corrosive chamber.
The outer finish is made with polyurethane paint on an epoxy base layer, thus protecting against UV rays and saline environments.
