Why use Priva Nutriflex?

Safe and reliable 

The basic principle is simple. Fertilizer tanks are connected to the Priva NutriFlex. These contain soluble fertilizers dissolved in water. The dissolved fertilizers are injected into the NutriFlex mixing tank, where they are mixed with water and pumped to the crop.

The NutriFlex can mix a maximum of eleven solutions simultaneously.The dual EC and pH measurements provide maximum reliability. The entire process can be controlled by the Priva process computer and possibly by other process controllers. The operating system for the NutriFlex is available in a variety of languages.

Flexible and efficient 

The NutriFlex can be used with every type of irrigation system and ebb and flood systems.
The acidity can be controlled with acid or lye. This makes the Priva NutriFlex extremely suitable
for applications of soilless growth systems. The system is available in a range from 5 up to 125 cubic meters per hour. Within these capacities, a number of system pressures are available. The Priva NutriFlex is easy to integrate into existing configurations and provide efficient solutions for any size of business. With deployment of the Priva NutriFlex, an increase of 15% in production can be realized.
