ClimaFlow System

With the ClimaFlow System, the grower can control the humidity in their greenhouse by bringing cold and dry air from above the closed screen into the greenhouse. The units draw air from above the screen into the greenhouse. This solution allows you to eliminate moisture-related diseases such as botrytis even with the screens closed.

With the system you get the opportunity to reduce negative effects of moisture or heat in a simple and energy-efficient method. The vertical airflow through the crop results in an optimally even microclimate.

The ClimaFlow System is suitable for any crop and is integrated into the greenhouse and screen installation. Changes in the cultivation or cultivation system do not lead to adjustments in the system unless the capacity must be increased, for example in heavily lit or colder crops. It suits most installation systems, is silent and easy to install and use.

Modules for connection to the horticultural climate computer are available from almost all leading computer manufacturers. The network controls and registers each fan separately, based on the control of a climate group in the climate computer.


How it works

The ClimaFlow System exists out of two parts. The white, top part is called the VentilationJet and below the Ventilationjet you find the ClimaFlow Fan. The VentilationJet draws the air from above the screen and distributes this below the screen. By having the vents open, the air characteristics, and especially the absolute humidity levels are different above the screen compared to the air characteristics below the screen.

By means of the VentilationJet, this air is drawn below the screen and distributed/mixed further via the ClimaFlow Fan through and within the crop. On the left & right side of the VentilationJet system, you see additional ClimaFlow Fans. These fans mix the air further within the greenhouse and create a homogenous greenhouse climate.

The system consists of VentilationJets in combination with ClimaFlow Fans, and standalone ClimaFlow Fans.


The ClimaFlow Fan is available in 2 motor versions: EC and AC


EC – version

How to calculate your need

For each project, a calculation is made for the number of units of the VentilationJet System®.

As a rule, we work with a pattern of approximately 256m2. The range of the VentilationJet System® depends, among other things, on the height of the greenhouse and the crop type.


ClimaFlow - Grow with the flow

ClimaFlow gives growers the ability to keep their climate screens closed, utilizing the screen to its fullest, achieving an optimal, progressive climate for their crop
