The RO-040-4750 is designed and manufactured by PSI water filters and produces up to 4750 litres per day (3.3 lpm). It is an affordable high output reverse osmosis system with an adjustable reject water ratio. The on-board pump boosts pressure up to 140 psi (980kpa)
The RO-040-4750 is designed and manufactured by PSI water filters and produces up to 4750 litres per day (3.3 lpm). It is an affordable high output reverse osmosis system with an adjustable reject water ratio. The on-board pump boosts pressure up to 140 psi (980kpa) and is adjustable.
We supply this unit in a small frame to reduce both manufacturing and shipping costs but its performance is not small for a unit of this size.
We have produced this model to compete with the Asian sourced units but on the whole using better quality components such as a U.S. sourced electric motor and Procon pump, genuine Jaco gripper series fittings and genuine John Guest tubing and fittings and Dow Filmtec membrane.
The unit uses the 10" x 4.5" big blue type housings with a sediment filter and a re-fillable carbon cartridge which reduces operating costs.
The membrane housing is in stainless steel with the Dow Filmtec XLE-4021 extra low energy membrane (higher performance at lower pressures).
The U.S. sourced electric motor to drive the Procon 102A125F11BB125 pressure pump is a ½ HP Marathon Carbonator motor with both 115 and 240 volt and supplied as 240 volt.
Supplied with twin pressure gauges, one gives the in-feed pressure from your water supply and the second gives the pressure being applied to the membrane after the Procon booster pump.
Supplied with twin electronic flow meters which give a digital readout of the flow rate for product and reject water flow rates as well as the ability to be programed to do a litre count down if you wish.
Dual point TDS meter (total dissolved solids) which reads the supply water TDS and the product water TDS.
The reject (waste) water ratio can be adjusted with the supplied needle valve so the unit waste ratio can be adjusted to suit the hardness of the supply water. In many cases the recovery ratio can be as high as 80% (20% waste) but that would be on water with a hardness below 400 ppm TDS, as the hardness increases so does the waste ratio. If this unit is to be connected to bore type of water a water test should be supplied so we can advise. The unit is not suitable for water above 2500 ppm TDS.
It pays to have a water test done and include a test for silica (Si) or silicon (Si)2) because these are both bad for all reverse osmosis systems
In the second photo you can see the stainless steel waste control needle valve. In the third photo you can see the in-feed, out-feed and waste water quick connect fittings. The blue tube is the in-feed, the black tube is the waste and the white is the product water.
This model is also available as a auto shut off model making it a high production automatic model, the auto model is $3200, also optional is large pressurised storage tanks in 38 and 75 litre sizes.
The option to up-grade the carbon pre-filter is going from a carbon pre-filter rated to remove about 100,000 litres for chlorine at 1ppm to a carbon cartridge rated to remove 750,000 litres of chlorine at 1ppm. Failure to change the carbon cartridge in time can result in a chlorine damaged membrane which is terminal for the membrane.
Allow 1-2 weeks before dispatch can take place as they are made to order.
