The RO-040-9500 is designed and manufactured by PSI Filters and produces up to 9500 litres per day (6.5 lpm). It is an affordable high output reverse osmosis system with an adjustable waste water ratio. The marathon on-board pump increases pressure up to 140 psi (980kpa) and is adjustable.
We supply this unit in an aluminium frame to reduce both manufacturing and shipping costs but its performance is not restricted 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. Sourcing the best quality USA made components including the marathon electric motor, Procon pump, genuine Jaco gripper series fittings, genuine John Guest tubing and fittings and Vontron or Dow Filmtec membrane (Optional).
The unit uses the 20" x 4.5" big blue type housings with a sediment filter and a re-fillable carbon cartridge which reduces operating costs.
The U.S.A 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. Power usage is 3.8 amps at 335 watts at a working pressure of 130 psi.
Supplied with twin oil filled 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 programmed to do a litre count down if you so 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 needle valve so the units waste ratio can be adjusted to suit it application as well as the hardness of the in-feed water supply. In many cases the recovery ratio can be as high as 80% (20% waste) but that would be on water with 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 2000 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
This model is also available as an auto shut off model making it a high production automatic model. The auto model is $5350.00, also optional is large pressurised storage tanks in 38 and 75 litre sizes at an extra cost.
The option to up-grade the carbon pre-filter is going from a carbon pre-filter rated to remove about 150,000 litres for chlorine at 1ppm to a carbon cartridge rated to remove 1.250,000 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.
When a higher waste ratio is predicted the system is supplied with a 3/4hp electric motor.
Allow 1-2 weeks before dispatch can take place as they are made to order.
