New fan system, the Verti-Fan

In recent years, greenhouses have become even larger and higher. This seems to be an advantage to a climate buffer. The fan systems most in use are installed high and only move the air horizontally and do not create any downwards air movement. 

Van der Ende Group from The Netherlands developed a new fan system that can transport the warm air downwards. 

The purpose of the Verti-Fan installation is to create a vertical air movement without causing too much air movements over the plants. To much air movements could prove detrimental to the crop.The vertical air movement is achieved using a fan that is fitted high in the greenhouse and which has a plastic transparent hose attached to it which transports the air downwards in a controlled way. The air which exits the hose under the crop will spread out over the ground and slowly streams upwards through the crop. 

The excess warmth that is frequently located high up in the greenhouse is then used beneath the crop which makes a considerable saving in energy possible. The air movement upwards along the crop activates the plant to a better CO² absorption. The crop also becomes drier, which reduces the chance of fungal infections. The Verti-Fan can also be installed to suck cold air away from the ventilation windows to cool down the crop from underneath.

 

Advantage of the system:

a better temperature distribution, limited variations in vertical temperatures, better distribution of the CO², better distribution of humidity and a huge saving on energy because the minimum pipes need to be used less frequently.

The Verti-Fan can be used in the cultivation of most vegetables and ornamental plants.

 

High-pressure and low-pressure Fog systems

The main goal of a Fog system is to create an ideal climate in your greenhouse. The Italian company Vifra Italy has developed a total stainless steel Fog system.

The high-pressure Fog systems pump unit generates a pressure between 70 to 120 bar. With the nozzles of this system its producing 1 micron size water drops. In this way the nebulized water doesn't deposit on the cultivation so it doesn't damage it. The anti drip nozzles are made of stainless steel with an ceramic core, this allows you as a user of this system to be able to spray chemicals with it and disinfect your greenhouse.
