HYDRO PLUS

Suitable for:  water heating systems, electric pumping systems, water hammering

Advantages: compact design with a seamless diaphragm that never stretches nor creases, no bubbles or corners to trap sediment, eliminating bacterial growth in the expansion tank.  International approvals for use with potable water, wide range available (from 0.5 to 158.5 gallons) .

 

Technical specifications: protected pre-charge valve. Durable 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. Butyl diaphragm, isolates water from air. Exclusive food-grade internal epoxy coating eliminating corrosion. External epoxy-polyester coating, therefore no rusting. Mild steel connection.

 

The ZILMET Hydro Plus expansion tank leaves the factory already tested and pre-charged. Air and water do not mix, thanks to a brazed pre-charge valve that prevents any possibility of water-logging through air loss to the system. Anti-corrosion tank design construction.

 

When the pump starts, water enters the expansion tank as system pressure goes over the minimum pressure pre-charge. 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 is needed again, pressure in the airside will push water into the system. The ZILMET Hydro Plus tank does not water log and delivers all available water, giving you minimum pump starts, minimum operating costs.
