Stationary anti-frost system SIS®

for orchardsfor open fields

The SIS® technology has the Selective Inverted Sump at the heart of its operation. It is a mechanical device that selectively drains the coldest air, which is the most damaging to crops, under the atmospheric conditions corresponding to radiation frosts. This drainage prevents the accumulation of cold air in the crop during all frosty nights. The SIS® drains the cold air and releases it at a height of eighty to one hundred metres, mixing it with the warmer air from the higher areas, neutralising and warming it. The number of SIS® required, the model of device to be used, and the precise the precise location of the equipment, is the result of a detailed technical and feasibility study that will be carried out in each case. The engines can be diesel, electric or powered by the cardan shaft of a tractor. In the case of diesel or electric, the operation can be automated, allowing it to start when the temperature reaches the desired limits. It is very quiet, thanks to the unique design and propellers. But the machine itself is really just a fan. It is only effective with the feasibility study, exact location and amount of equipment needed.
