Positive test results of the Multifan V-FloFan in German greenhouse
A German research centre has performed indicative tests with the Multifan V-FloFan. Because of the obstacles in the relative low German greenhouses, the horizontal recirculation fans do not always reach the optimal throw. The first tests (ornamental plants on tables) with the Multifan V-FloFan, show that a homogeneous temperature spread can be reached with vertical ventilation with low air speed on plant level (0,1 till 0,2 m/s). The warm air below the screen is spread in the whole greenhouse, after switching on the fans. The temperature difference of more than 5°C between screen height and plants could be reduced until 0,5 °C, independent of the present obstacles.
