All Xsential reverse osmosis systems come with a storage tank. A pressurized storage tank for reverse osmosis water is needed to deliver reverse osmosis water to the faucet or appliance using air pressure within the tank. Water is stored in a bladder within the tank vessel opposite the pressurized air.
As the bladder fills, the back pressure increases until it reaches a pre-set pressure limit (as determined by a shut-off valve, sold separately), causing the shut-off valve to cut off the feed supply to the reverse osmosis system. Water will remain in the bladder until the faucet/appliance solenoid is opened, the air pressure surrounding the bladder will force the water out of the storage tank and a directed point of use. As water is used, the pressure will drop until the shut-off valve disengages, allowing feed water to the RO system to resume until the tank is refilled.
Xsential reverse osmosis system pressure tanks use a butyl diaphragm and polypropylene liner to separate the water and air.
These materials limit the growth of germs and prevent impurities inside the tank.
