Water goes through a reverse osmosis membrane very slowly and people do not have the patience to wait a long time to get a cup of water. For this reason
residential RO units need a water storage tank to store the purified water. The RO tanks can deliver stable and constant water flow when the faucet is opened. The concern that pollutants might come from air or animals with the use of an open tank favors the use of a closed expansion tank.
Lead leaching to drinking water is the cause of health risks, brass and copper are banned for use in purified/drinking water. All RO Tank expansion tanks use stainless steel connections to avoid the lead leaching concerns.
To avoid bad odors from diaphragm, all of our diaphragms are post cured before assembly to eliminate the possibility of odors from the tank.
Tanks are NSF approved under standard 58, and CE approved under the PED (pressure equipment directive), because of these approvals our tanks carry appropriate markings and can be used everywhere in the world.
