Link4’s iDoser is the automated dosing system that growers have been waiting for. Imagine a system that helps to predict your plants’ needs, even before you do. That kind of control is possible with Link4’s iDoser system, a stress-free solution for automated dosing and fertigation scheduling.

The iDoser provides accurate nutrient dosing, and pH balancing for many different types of grow environments – from large-scale greenhouses to commercial warehouses and vertical farms. Plus, given that the LinkConn software is database-driven, it can be controlled by an enterprise-grade server or installed right onto your laptop for optimal control and visibility. The iDoser system can also include up to two backup sensors and logs all activity so, if a problem does occur, you’re on top of it before it becomes an even bigger problem. This helps you pave the way for efficient and plentiful growth you can rely on.

LinkConn Greenhouse Control Software

LinkConn control software is a way to heighten a garden’s efficiency while compiling important historical data. The new LinkConn 1800 software has been proven successful in applications requiring different zones, e.g. transplants and seed beds. In a traditional system that utilizes multiple zones even minor changes can be very labor intensive, but with Link4’s LinkConn software, growers can conveniently control all of their remote hardware through a single PC. All settings can be modified in groups; saving the grower time and reducing errors.

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 X- 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 X – 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.

Instrumentation

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
