HYDRO-PRO-ITALY

Description

HYDRO-PRO: is our line of compact expansion tanks for sanitary hot water with a fixed potable water butyl membrane and internal epoxy coating. These expansion tanks are made of carbon steel and MIG welding that 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. These expansion tanks are used with boilers, water heaters, pump systems and as anti-water hammer. The sizes range from 5 to 600 liters (1 to 132 UK gallons). They are certified according to PED 2014/68/EU, WRAS, ACS, IAPMO and NSF. NPT fittings are available on request.

Vantaggi

Il vaso di espansione HYDRO-PRO, con il suo design compatto e il funzionamento ottimale della membrana non facilita la crescita batteriologica. È inoltre omologa-to a livello internazionale per l’uso con acqua potabile ed è disponibile in un’ampia gamma di modelli, con una capacità da 2 a 600 litri.

Caratteristiche tecniche

Valvola di precarica con protezione. Vaso in acciaio al carbonio per una lunga durata. Il sistema esclu-sivo di saldatura MIG elimina ogni spigolo o profilo tagliente all’interno del serbatoio e previene danni alla membrana e al rivestimento interno. Camera pressuriz-zata. Membrana Zilan DW per isolare l’acqua dall’aria. Rivestimento esclusivo interno con polvere epossidica per evitare ogni corrosione. Vernice epossi-poliestere esterna evita la ruggine. Raccordo in acciaio.

Advantages

Compact design with a seamless diaphragm, that never stretches or creases. There are no bubbles or corners to trap sediment, inhibiting bacterial growth; international approvals for use with potable water. Wide range available (from 2 to 600 litres).

echnical features

Protected precharge valve. Durable steel tank. Deep-drawn steel shell for extra strength. MIG welding process eliminates interior rough spots and sharp edges and prevents damage to diaphragm and liner.
Pre-pressurized air chamber. Zilan DW diaphragm isolates water from air. Exclusive internal epoxy coating : no corrosion. External epoxy-polyester coating : no rusting. Mild steel connection.

Working

The Zilmet HYDRO-PRO tank leaves the factory already tested and pre-pressurized. Air and water do not mix, eliminating any possibility of “water-logging” through loss of air to the system ; no corrosion.When the pump starts, water enters the tank as system pressure passes the 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 its maximum capacity. When water will be needed again, pressure in the airside will push water into the system. Since the Zilmet HYDRO-PRO tank does not water log and delivers all possible water, minimum pumps starts are assured.
