One reliable dosing system family, different applications
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
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
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.
How does Priva realise the highest quality at the
lowest cost per/m3?
Priva units are able to realise a stable pH and EC of your
irrigation water. The right pH level at the rootzone is essential
for optimal uptake of nutrients. This prevents deficiencies and
diseases and provides excellent plant quality. The right
amount of water and nutrients at the right time means the valuable
nutrients are being used as effectively as possible. This is
realised by our advanced controls and our robust and reliable water
