Frost protection thermal fogger machines is used for 4 different purposes
1) Agricultural frost protection,
2) Pest control,
3) Fungicide and bacteria control and
4) Fertilizer applications.
In Agricultural Forst Control, the devices generate a dense thermal fog of a very large micron spectrum. This artificial cloud forms a protective layer around trees, flowers, and seeds, increasing their resistance to low temperatures and helping to prevent frost damage to crops.
The protective artifical cloud layer reflects back the warmer air of the ground , preventing it from escaping into the atmosphere and preventing heat loss from the soil.
At the same time, the artifical cloud pushes back the cold air mass descending from sky which tends to sink onto crops. The artificially created cloud acts as a blanket, it has a density between the two air layers: warm air on the ground, cold air mass descending from sky, therefore remains suspended as a stable layer above the plants up to 3h, till the smoke is thinned out.
This artificial cloud curtain has three key protective effects:
1. It pushes the cold air upward, preventing it from settling directly on the plants.
2. It reflects ground heat back downward, significantly reducing heat loss.
3.Thanks to the moustorizing effect of the antifreeze vapor, the crystallization and freezing of water molecules within plant tissues is delayed.
The artificial cloud forms a three-dimensional thermal fog barrier extending from the ground surface up to the cold air layer above. Since radiation frost occurs in the absence of wind, in open fields, this fog layer remains suspended in open fields for an average of up to 3 hours, providing full protection down to –7°C, and partial protection if the air is colder than –7°C.
In greenhouses the artificial cloud remains suspended in the air for approximately 6 hours, offering extended protection against frost risk.
This technology is safely used in orchards, vineyards, greenhouses, vegetable fields, and various afforestation areas. It provides full protection down to –7°C and partial protection at temperatures below –7°C.
