Galcon’s unique Fertigation Machines are devices for mixing fertilizer in the irrigation water.

Galconױs unique Fertigation Machines are devices for mixing fertilizer in the irrigation water.

The fertilizer is injected to the pressurized water system via venturi pumps. Up to 8 channels of fertilizer injection can be employed together.

The Green House cultivation applies hydroponics irrigation whereby plants grow in a substrate (soil-less). In these conditions the plants must receive all of the nutrients N-P-K which finally should reach EC (electric conductivity) and pH (acidity) level. Therefore it requires that the fertigation will be carried out according to the EC/pH of the irrigation water. Another advantage of irrigation according to EC/pH control is the ability to maintain the desired concentration of the fertilizer in the water regardless of preparation error, material chemistry construction etc.

Dagan

Drainage sample machine, compatible with Galileo controller

The Machine Components

The structure of all machines types include:

  • Aluminum Frame: Strong, modular, non corrosive.
  • Piping and Fittings: PVC non corrosive piping installation.
  • Electric Table: All of the necessary connections to be ready for use including starter for the booster pump.

Venturi Pump

This ׂT׃ shape device converts the speed of the water into suction and causes the fertilizer to mix in the water. Two models are available:

  • Standard model - 350 liter per hour / 92 Gallons per hour.
  • High flow modes - 1200 L/H / 317 Gallons per hour

The venturi pump contains:

  • Venturi body: a ׂT׃ shape body with a unique nozzle inside.
  • Electric valves: Installed on the entrance of the Venturi body it can be either fully open or closed. It is connected to the controller and is controlled by it. The controller calculates the required injection rate and operates the solenoid accordingly.
  • Flow Meter: A transparent conic tube with a ball inside. The ball rises

according to the momentary flow rate of the fertilizer.

It is equipped with a small valve for adjustment of the flow rate.

  • The Fertimeter: (optional): A fertilizer meter that sends pulses to the controller thus enabling fertilization according to volume.
  • ¥ Hydraulic Normally Closed Valve: To prevent the leakage of fertilizer into the empty line while the system is idle.

Booster Pump

An electric stainless steel (non corrosive) pump, ranging up to 15 HP - depending on the type and size of the machine. The booster pump causes the high speed flow through the Venturi thus enabling the suction of the fertilizer. In the FertiMix it also builds up the pressure and supply the irrigation water.

¥ Electric Pressure Stat - to prevent operation in the electric pump in ׂNo Water׃ conditions.

¥ A Pressure Sustaining Valve to prevent cavity in the Electric Pump.

¥ Level Sensor for automation and information.

The EC/pH System

A system that includes a sampling cell with two electrodes EC and pH, that are connected to an electronic monitor. The monitor converts the electrodes signal to a standard 4-20 mA signal read by the Galileo Controller. The Monitor is equipped with a display and a keyboard enabling the constant and clear presentation of the readings during operation.

The monitor also serves for calibration of the electrode readings.
