PX2-Series Reverse Osmosis Systems are engineered to treat demanding feed water conditions, such as low temperature or a high content of dissolved solids and are ideally suited for brackish water with total dissolved solids (TDS) in the range of 5,000 to 10,000 ppm.

The design of our PX2 Series produces superior quality filtered drinking water which delivers consistently clean, purified great-tasting water. All of our reverse osmosis water systems provide a low-maintenance, chemical-free option to help achieve clean, great-tasting water each and every day. Choose any PX2 Series configuration and you will receive one of the finest quality, high-capacity RO filtration systems available today.

The models of the PX2-Series range in capacity from 20 to 125 gallons per minute (30,000 to 180,000 gallons per day). Using high efficiency, 8-inch reverse osmosis elements with a 10% greater membrane surface area, Planet Water’s PX2-Series systems are able to significantly reduce the TDS in both municipal and well water sources while producing higher volumes of permeate. Low energy brackish membranes are available for cold temperature applications and high rejection brackish membranes are available for high TDS applications. The PX2-Series product line features a pre-programmed computer controller, motorized feed valve, TDS probes, and panel-mounted pressure and flow instrumentation. The larger models include digital indication flow and VFD motor control. Stainless steel components are used for the vertical multistage pump, cartridge filter housing, high pressure piping valves, and the ports of the FRP pressure vessels. High pressure hose is employed for ease of maintenance.
