How does the FrostGuard work? PDF Print E-mail

The FrostGuard has a gas burner and a powerful fan, driven by petrol engine that runs on propane gas. You just have to start the engine, adjust the temperature and the FrostGuard does the rest. There is  gas to last one complete night.

The success and effectiveness of the Frostbuster are a result of the temperature fluctuations that are created by the machine, and of the lowering of the humidity, reducing the possibility of ice crystals form. The big advantage to creating fluctuations is to use much less energy than raising the temperature above the critical values constantly, and still maintain effective frost protection for your crop. As a result, the input of energy is up to 10 times less than with other systems, and your crop is still fully protected.

The FrostGuard works the same way. The big difference between both machines is that the Frostbuster is powered by the tractor, which must be driven through the orchard at night, while the FrostGuard, once started, stays at the same place and needs no supervision. The outlet of the fan turns around 360° continuously, protecting an oval or round area. Machines can be spaced out in groups in relation to the shape and area to be protected. Another important advantage of the FrostGuard is that it’s easy to spread the investment over several years: you can start with 1 or 2 machines and buy more during the following years. Therefore, no big initial investment is necessary.

There are 3 factors that make the FrostGuard 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 little damage.
