How does the Frostbuster work? PDF Print E-mail

The Frostbuster is a trailed machine. The powerful fan is driven by the PTO of the tractor. In the air inlet of the fan, there is a gas burner that heats the air up to 80 to 100° Celsius. At the back of the machine are the containers for the gas bottles.

The heated air is blown between the trees through 2 outlets (1 at the left and 1 at the right). Because the air flow is so powerful, we cover a distance up to 40 to 50 meters at each side of the machine. Therefore, it's only necessary to drive through the rows every 60 to 90 meters. We will calculate for you the ideal circuit which is different for almost every orchard. However, it is very important to pass at the same spot within 10 minutes. The total surface that can be protected depends on the shape and the dimensions of the plot.

There are 3 factors that make the Frostbuster work:

  1. The increase of temperature.
  2. A very important factor is the creation of temperature fluctuations: at each passing of the Frostbuster, the temperature rises shortly and drops again. These fluctuations create a big part of the protection that we get with the Frostbuster.
  3. Probably the most important factor is the influence on the relative humidity. Wherever the Frostbuster is used, the relative humidity goes down. Because of this, the dew point is raised significantly. Therefore, there will be less hoar-frost and less ice on the plants. Result: no or very litlle damage.
