Fertirrigation

Products and solutions to implement fertigation systems based on hydraulic operation for greenhouses, open field crops, soilless and hydroponic growings. The venturi injectors represent a cost-effective and user-friendly solution for many professionals, you can buy them both singularly or equipped with all accessories as foot valve, suction hose, reguation valve, hose clamp, venturi injector.

VENTURI INJECTOR'S PRINCIPLE: a venturi injector uses excess pressure in the irrigation system to create a low pressure zone or vacuum in the injector throat. Venturi injectors represent the safest, most efficient and cost-effective equipment to inject liquids or gas into a pressurized line. The injector operates on the principle of vacuum suction created by an advanced Venturi complex. This implements the latest know-how in hydraulic technology and allows the injectors to operate at small pressure differentials. Injection is activated at the chemical inlet, when there is a pressure differential between the water entering the injectors and the water and chemical leaving to the irrigation system. Venturi injectors are resistant to many chemicals used in agriculture.
