Global Water Challenger™ Series is a maintenance-free pressure tank made of carbon steel. It delivers stable performance, long service life, and high reliability for pressurized water systems. In addition, the tank uses patented CAD-2 diaphragm technology to separate air and water effectively while reducing internal condensation.

Moreover, the Challenger™ Series features a 100% chlorine-resistant butyl diaphragm, a virgin polypropylene liner, and a stainless steel water connection. As a result, the system maintains water quality and operates efficiently. Furthermore, the air buffer chamber design prevents direct contact between the diaphragm and the tank wall, which helps reduce corrosion and extend service life.

Finally, the tank is finished with two-part polyurethane epoxy-primed paint, making it highly resistant to harsh environmental conditions. Each unit also undergoes comprehensive factory testing at Global Water Solutions’ production line. Therefore, the tank delivers long-term structural integrity and reliable performance without the need for routine maintenance.
