Flowvess CHP-V Expansion Vessel

The flowvess CHP-V expansion vessels are ideally suited for a wide range of applications, including booster systems, thermal expansion, heating expansion, irrigation systems, and hydraulic hammer arresting.
Efficient and cost effective, Flowvess tanks are designed with a patented controlled action CAD2 diaphragm assembly. It features a chlorine resistant 100% butyl diaphragm with a precision moulded copolymer polypropylene liner for superior air and water separation.
The CAD2 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 “air buffer” design means few problems with condensation. The two part polyurethane paint finish over an epoxy undercoating provides UV and salt spray protection.
Constructed with an FDA approved high grade butyl, the diaphragm assembly seals water in a true non-corrosive chamber.
