V-FloFan applications

V-FloFanImportant notes (WUR): “ The New Cultivation”

• No temperature differences, which occur because of cooling across the

screen or heating from the lightning, as a result of airflows over long distances across the screen

• The vertical airflow realizes an active microclimate on crop level and high crops

• Uniform airflow over a higher surface

• Heat from sun or lightning are transported down effectively by movement without increasing the pressure and with the lowest energy level as possible (as is the case when using tubes)

• Because of the correct division between the fans there is both a vertical balance as well as a small horizontal balance

Effective advantages – conclusions:

• Optimal air distribution for prevention of vertical temperature differences

• Improved control of humidity level on crop level

• Reduction of energy costs

• EIA 2013 subsidy (Netherlands only)

• Constant low air speed on all levels

• Optimalisation of an active micro climate

V-FloFan applications

V-FloFan applications

• Horizontal ventilation: on average 1 fan per +/- 600 m²

• Vertical ventilation: on average 1 fan per +/- 360 m²

In comparison to existing vertical systems very efficient
