Combining reverse osmosis and ion exchange technologies this smart water purification system provides a high quality and economically produced purified water for many laboratory tasks.

Units are suitable for bench mounting. An optional wall mounting bracket is available which should be specified separately. Supplied complete with connection hoses, pre-filter, RO membrane and deioniser cartridge. For use only on potable (drinking) water supplies.

High purity water

Offered in three volume outputs to suit most laboratory daily needs the Fistreem MultiPure RO Water System has the advantage of removing the majority of feed water impurites from potable ( drinking ) water by reverse osmosis prior to a final purification process by high quality ion exchange resins. In addition a carbon pre-filter protects the RO membrane from potentially harmful feedwater impurities.

High output, convenient storage and dispense

Nominal production rates of 6 ,12 & 24 litre per hour * are offered. An integral Reservoir Tank maintains a nominal volume of 20 lts which is constantly replenished . A fast flow dispensing tap is ideal for routine lab requirements. In addition a second gravity outlet allows the unit to have a permanent feed connection to external equipment.

The long life reverse osmosis membrane ensures the feedwater to the deionising cartridge is free of most impurities so providing a high volume output from the DI cartridge with high economy. On exhaustion the disposable cartridge packs are very easily replaced.

* based on feedwater @ 25C 60 p.s.i.

Smart display panel

Water purity is constantly monitored and displayed on a smart easy to read meter. A visual indicator and alarm alerts the user to the need to replace the deioniser cartridge pack.

Boost pump option

For users with low feedwater pressure the boost pump option is essential. The pump is positioned internally within the cabinet. This variant must be specified when feedwater pressure is below 2 bar (30 p.s.i.)
