INTRODUCTION
The unvented cylinder is made from Duplex Stainless
Steel for excellent corrosion resistance. The unvented
cylinder has a strong rust-proofed steel case and is
highly insulated with environmentally friendly foam.
The cylinder is supplied complete with all the necessary
safety and control devices needed to connect to the
cold water mains. All are pre-adjusted. High quality
controls have been selected to combine high flow rate
performance with minimum pressure drop to make the
unvented cylinder perform well in all areas, even those
with poor water pressure.
