Advantages
Compact design with seamless diaphragm inhibits bacterial growth.
This range is certified according to PED 97/23/EC, WRAS/WRc, ACS, IAPMO, and NSF.
Stainless steel connections
Technical features
These are compact expansion tanks for sanitary hot water with a fixed potable water butyl
membrane and internal epoxy coating.
These tanks are provided with a stainless steel fitting.
MIG welding eliminates any sharp cutting edges inside the tank.
The shape of the membrane is designed to avoid any water stagnation and therefore the
growth of any bacteria. External epoxy-polyester coating: no rusting.
Working
The Zilmet WATER-PRO tank leaves the factory already tested and pre-pressurized.
Air and water do not mix eliminating any possibility of “waterlogging” through loss of air
to the system water; no corrosion possibility.
When the pump starts, water enters the tank as system pressure passes the minimum
pressure precharge. Only usable water is stored.
When the pressure in the chamber reaches the maximum system pressure, the pump
stops working. The tank is filled to the maximum capacity.
When water will be needed again, pressure in the air side will push the water in the system.
Since the Zilmet WATER-PRO tank does not waterlog and delivers the water, minimum
pump starts are assured.
