Hydroponic Systems

With our many years of experience in assembling equipment for hydroponic systems, Polytechniek developed a standard setup for water treatment. ecause we assemble all the necessary parts in-house, we can assemble the entire water treatment system in our workshop and ship it locally or globally as one single package. Our hydroponic setup is usually equipped (for each basin) with the following components.
  • Self-priming energy-efficient system water pump with a capacity contingent on the number of Grow Trays per basin.
  • Bypass circuit for regulating the water pressure in the pipe to the Grow Cell.
  • Electric clean water supply valve with electric level controls to keep the water in the basin at a constant level.
  • Analog mechanical water meter with or without digital pulse measurement.
  • Water temperature sensor
  • Complete cooling set, including a stainless steel cooling coil or cooling plate with a capacity based on the amount of chicory roots to be irrigated, a coolant regulator dependent on the type of cooling system.
  • For further aeration of the water, each basin is equipped with a jet-air venturi aerator.
  • Complete hot water system for heating, including a stainless steel coil with capacity based on the amount of chicory roots to be irrigated.
  • Complete fertilisation system including EC/PH transmitters for measuring the EC-PH value.
  • Custom-made control technology.

Alarm circuits will be installed with our control and operation technology in order to detect system water pump failures such as:

  • Extremely high or low EC values.
  • Extremely high or low pH values.
  • Extremely high or low process water temperatures.
  • Fertilisation system.
  • Electric heating instead of hot water heating.
