500 litres per hour from the PureFlo RO water filter

The Condair PureFlo RO water filter can now deliver up to 500 litres of demineralised water per hour to a humidification system. The filter is an all-in-one water treatment system, requiring no associated pumps or tanks to operate. Three models supply up to either 100, 250 or 500 litres of RO water per hour at a supply pressure of up to 3bar.

By removing the minerals from a humidifier’s supply water the limescale that builds up in the system is virtually eliminated. This results in a much lower level of required maintenance in all types of humidifier and reduced energy consumption in steam humidifiers.

These cost savings can lead to a payback on the initial purchase of the RO (reverse osmosis) unit in around one year.

Steam humidifiers that run on mains water need to drain their boiling chambers occasionally to maintain a low mineral content and reduce limescale build-up. By using RO supply water, the steam humidifier’s boiling chamber does not require this regular drain. Therefore it uses less energy to maintain the water’s temperature.

As the water temperature is consistent, the steam output is also consistent thus improving humidity control. By using resistive steam humidifiers fed by RO water ±1%RH control can be achieved.

Other benefits of using RO water with humidifiers include increasing the life of the evaporative pads in evaporative humidifiers and preventing dust carry-over in spray humidifiers.

The system has a typical dissolved solids rejection rate of up to 95% and a very high recovery rate, delivering up to 50% of the supply water as RO water.

The unit comes complete with a 3-stage pre-filtration assembly that removes chlorine and any non-dissolved particles down to one micron.

The PureFlo RO has a 23 litre water tank providing a large quantity of RO water on demand and four pressure gauges showing inlet water pressure, filtration pressure, pump pressure and outgoing water pressure.
