From Water Management
For healthy crop growth you want the right dosing system for the fertilisers that are needed. A system with stable dosing, without fluctuations in EC and pH as a result of which your crop can absorb the fertilisers successfully. You will immediately see this in the crop quality and your production yield. Whether you work with hydroponics or substrate cultures. With the Priva Nutri-line fertigation of your crop is perfectly controlled. Which dosing system do you need?
Similarities: efficient and reliable
The NutriFlex, NutriFit and NutriJet have many similarities. All three allow you to fully control fertiliser dosing, taking account of flow, EC, pH, light, outside conditions, etc. The dosing rate is memorised and used immediately in a subsequent cycle. This reduces fine-tuning requirements.
All Nutri-line products work with overhead irrigation, drip irrigation and ebb and flood systems and are suitable for all protected and outdoor crops. Priva fertiliser dosing systems have a long service life and are reliable in use.
Differences: system and capacities
The NutriFit and NutriFlex dose the fertilisers into a mixing tank with fresh water first. The NutriFit is able to dose water flows of up to approximately 25 m3/hour and the NutriFlex up to approximately 80 m3/hour. The number of dosing channels on the NutriFit and NutriFlex is modular and can be expanded to a maximum of five and ten respectively.
Using the Inline-system on the NutriJet you can dose directly into a closed mixing chamber with water flow capacities of up to approximately 80 m3/hour. Because the NutriJet only uses a single pump, the system is more energy-efficient. In a Bypass design you can easily increase the capacity of the NutriJet to dose water flows in excess of 100 m3/hour.
In addition to the standard fertiliser dosing channels the NutriFlex or NutriJet can automatically blend very low doses of trace elements and cleaning agents using separate low-volume dosing channels.
The Nutri-line can function as a stand-alone unit or be centrally controlled by the process computer.
This allows you to link your systems even further; to water management, climate controls, energy management and management information systems for example, whatever product you choose.
Nutri-Line at work
Priva and its UK dealer network launched the first 'modular', fully-fitted containerised pump house.
Priva dealer C.L.A.I.E recently installed a Priva Connext process computer (with Priva Office Direct user interface and integrated NutriFit water unit) in four greenhouses and a central hall in the compact research location south of the Loire. Watch the video below for more info.
