R1 – Series Reverse Osmosis Systems

Link4 RO Systems
  • UL/CUL listed Microprocessor Controller with NEMA 4X rated enclosure
  • Up to 80% achievable System recovery, dramatically reducing the wastewater to the drain
  • High grade steel construction and heavy-duty powder coating to withstand harsh environments.
  • Variable frequency drive for 15hp motors and larger. Optional for 10hp units.
  • High-efficiency vertical stainless-steel multi-stage pump coupled with high-efficiency motors.

Link4 Corporation is partnering with AXEON, a world leader with 30 years of experience in engineering and manufacturing innovative membrane and filtration systems, to bring its customers the best reverse osmosis (RO) solutions for their growing projects. The AXEON R1- Series of Membrane Systems utilizes reverse osmosis technology to produce high purity water by reducing contaminants such as dissolved minerals, particulates, and organic impurities. Link4 and AXEON combine their skills and technology to be able to provide customers with complete water treatment solutions that offer reliable operation and exceptional performance. These solutions are skid-mounted, pre-plumbed, and pre-wired for quick installation and start-up. Allow our team to assist you in designing your next water treatment solution.

Skid and Frame Assembly

Membrane systems are manufactured in a skid frame design for ease of installation with minimum floorspace requirements. AXEON R1 – Series Membrane Systems are constructed of welded structural carbon steel tubing and finished with corrosion resistant epoxy powder coating. Stainless steel fasteners and hardware is standard for added corrosion resistance.

Cartridge Pre-Filtration Housing

Integrated prefiltration is standard on all systems.

System Pressure Pump

Standard pressure pumps are constructed with 304 / 316 stainless steel housings, as well as impeller and diffuser stage assemblies. Pumps are equipped with TEFC motors and wired for 230 / 460 VAC voltage, and rated for full load, continuous duty.

Membrane Housings

All systems feature membrane housings constructed of fiberglass reinforced polyester (FRP) with 316 stainless steel side–entry feed and concentrate ports. Standard housings have a white polyurethane finish and are NSF61 rated. ASME code–stamping is available on all membrane housings.


All systems feature a complete instrumentation package for optimal performance monitoring. Each of the following instruments are panel–mounted and pre–wired:

  • Pre– and Post–Cartridge Filter Pressure Gauges
  • Pump Concentrate Pressure Gauges
  • Reverse Osmosis Inlet Pump Discharge Pressure Switches
  • Permeate and Concentrate Electronic Flow Sensors or Rotameters
  • Permeate and Feed Conductivity Monitor
  • Temperature Sensor
  • Pump Run Hour Meter

Membrane Elements

Standard reverse osmosis membrane elements are high rejection, thin–film composite (TFC) type, in a spiral– wound configuration. Membrane elements are tested and carry a one–year warranty against defects in quality and workmanship.

System Controls

Operation of the systems are automatically controlled through a comprehensive microprocessor controller housed in a NEMA – 4X industrial electrical enclosure. The control system also includes a pre–wired motor starter, operator switches, push–buttons, and status alarm indicator lights. Standard systems include the following isolated alarm conditions:

  • Low Inlet Pressure
  • High Pump Discharge Pressure
  • High TDS

System Piping and Valves

All membrane systems are completely pre–plumbed and installation ready. Sch80 PVC is used for all piping and valves under 75 psig operating pressure. Higher pressure piping and valves are constructed of 316 stainless steel for the X2 and X3. The following valves are provided as standard for accurate flow and pressure control and convenient operation:

  • Automatic Inlet Valve to Prevent Water Flow through the System During Shutdown
  • Pressure Pump Discharge Throttle Valve
  • Reverse Osmosis Concentrate Valve
  • Optional Recirculation Valve
  • Automatic System Flush Valve for Prevention of Membrane Fouling and Scale Formation
  • Inlet and Sampling Valves
  • Individual Membrane Housing Product Sampling Valves
  • CIP Ports for Use with Membrane Cleaning System
