How the Smart2Pure system functions
When the system is in operation, tap water with a maximum pressure of 6 bar flows into the
system and is pumped by pressure booster pump 1 through the RO/pretreatment cartridge.
The RO/pretreatment cartridge splits the feedwater by reverse osmosis technology in
“permeate and “concentrate“ water flow. The concentrate water flows to drain.The permeate
of the reverse osmosis membrane flows into the internal 5L tank or by Smart2 Pure 12
systems into the external pure water tank. If the internal or external pure water tank is filled
with maximum capacity with water of ASTM Type II, the feedwater solenoid valve is closed
by a level switch and prevents that no more water flows into the system.
After open the dispensing valve the pure water from the tank flows through the UV bulb ( only
systems with UV ), ultrapure cartridge and the ultrafilter ( only systems with UF ). ASTM Type
I water can be dispensed through the 0.2 μm final filter on dispensing valve and ASTM Type
II water when you have connect the accessory hand dispenser on the connection panel of the
system.
The water in the internal or external tank is recirculated at regular intervals through the
pressure booster pump 2 to ensure the constant quality of pure water ASTM Type II. A level
switch monitors the water level inside the tank.
ASTM Type II water can be dispensed from the side outlets of internal tank from the
connection panel or from the front valve of the external tank.
