Challenger 450 Litre Expansion Vessel GCB-450LV

Challenger^™ tanks are ideally suited for a wide range of applications including:

• Booster systems
• Well systems
• Irrigation systems
• Thermal expansion
• Hydronic heating expansion
• Hydraulic hammer arresting
• Clean water backwash for Ultra-filtration systems

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 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.
