Frost protection
From the point of view of fruit growing, global warming means one thing above all: the trees sprout earlier and the period in which late frosts endanger the success of an entire season is getting longer. In addition to the choice of location and variety, it is therefore important to actively protect the sensitive flowers from late frosts.
There are various methods of frost protection in fruit growing. The classic methods are frost protection irrigation and the supply of heat using frost protection candles. Gas or oil burners with fans set up between the rows are also used. Helicopters or windmills are also used to counteract low temperatures.
However, not every method is suitable for every orchard and every type of weather. Freezing winds, in which cold air fronts push icy air through the rows of trees, may require a different approach than radiation frost, which occurs during inversion weather conditions when warmer air layers over the cold air at ground level.
Smoke candles and fog machines are used to simulate the now-banned practice of smoking, and are particularly suitable for use with radiation frost. They are designed to have a similar effect to real fog, by preventing the cold air from sinking and storing the heat energy in the fine water droplets. It is important that the surface is completely covered with fog.
VICAR radial fans achieve precisely this surface coverage thanks to a higher air speed with a lower air volume at the same time compared to other types of fans. This means that the air can be distributed further as a carrier of the fog and thus over a larger area, resulting in effective and economical frost control.
Advantages of VICAR radial fans
- Greater range
- Cost savings due to lower use
- Long service life thanks to high-quality materials
Ideal for frost protection in fruit and fir cultivation in terms of performance and range
In terms of performance and range, the turbines in the 440, 450 and 540 series are ideally suited for frost protection with fog.
The 451 and 541 series turbines are suitable for frost control with wind.
