Priva Nutrijet: Efficient dosing via direct injection

Efficient dosing via direct injection of fertilizer.

For healthy growth of the crop, it is of great importance to use the correct dosing system for the required fertilizers.

Introduction
The Priva NutriJet is an attractive alternative to a mixing tank system.

The NutriJet injects the fertilizer solution directly in the irrigation mainline. This process is reflected in the crop quality and production yield. A major advantage is that an extra fresh water pump is not necessary. The Priva NutriJet allows injecting up to ten fertilizer solutions simultaneously.

Why use Priva Nutrijet?

Safe and reliable 

Dissolved fertilizers are injected from the fertilizer tanks and mixed in mixing chambers with irrigation water. The result is a highly concentrated solution, injected into the irrigation line where it is diluted with the irrigation mainline to the desired concentration. The dual EC and pH measurements provide maximum reliability. The entire process can be controlled by a 

Priva process computer and possibly by other process controllers. The operating system for the NutriJet is available in a variety of languages

Flexible and efficient 

The NutriJet can be used with overhead or drip irrigation and ebb and flood systems, for indoor or outdoor equally as well. The system design allows either in-line or by-pass configurations. The NutriJet is available in several sizes and capacities from approximately 5 m3/hour (22 gpm) to over 80 m3/hour (352 gpm) – with higher flow rates available to order. The fertilizer injectors are adapted to the desired capacity. Because the NutriJet uses only 

one pump, the system is more energy efficient. The Priva NutriJet is easy to integrate into existing configurations and has a very attractive price per performance ratio, which is even more attractive when it is applied in a by-pass configuration.

Durable and low maintenance

NutriJet systems are extremely durable and require very little maintenance. The system is made of stainless steel and sustainable plastics, with minimal moving parts as a result of using venturi dosing.
