## ProTank PV Pressure Vessels in the UAE

Villas and towers in the UAE rely on pumps to move water from tanks to taps. A correctly sized pressure vessel cuts pump starts, smooths pressure and reduces water hammer.

ProTank PV comes in inline, horizontal and vertical forms, factory pre-charged to 2.6 bar and rated to 10 bar. The water touches only the liner, so there is no taste or odour from the steel shell.

## Questions and answers

### Why does a booster pump need a vessel?

The vessel stores a small amount of water under pressure, so the pump does not start every time a tap opens. That saves the pump and smooths the flow.

### Can it buffer an RO system?

Yes. RO permeate buffering is a standard use, alongside booster and well systems.

### What if I need more than 160 litres?

Larger Challenger vessels up to 450 litres are available on request.
