Martignani spraying technology

Since 1946...

...leaders in "Mist-Blowing" and "Low Volume" Techniques

...since 1981 in "Electrostatic" Spraying System


The "MARTIGNANI" mist blowers employs a pneumatic mist spray, which has been successfully in use all over the world since the first "Kiekens Dekker" patents were introduced. It assures: - high speed operation - very fine and constant mist regardless of the water flow rate - uniform coverage and distribution of chemicals - exceptional working range and penetration in any crop, of whatever shape and even in difficult weather conditions - superior efficiency in fungicide and insecticide spraying and in particular in treatments to eliminate weevils, cochineal insects, mites, aphides, etc. - savings:

  • WATER over 90%
  • CHEMICALS over 30%
  • LABOUR/TIME over 60%
  • FUEL over 40%

with no damage to plants (liquid at low pressure) and no soil pollution (no run-off from leaves). The "MARTIGNANI" electrostatic mist blowers can spray:

  • HIGH VOLUME (over 1000 l/ha - 100 usg/acre)
  • MEDIUM VOLUME (500-1000 l/ha - 50-100 usg/acre)
  • LOW VOLUME (200-500 l/ha - 20-50 usg/acre)
  • VERY LOW VOLUME (50-200 l/ha - 5-20 usg/acre)
  • ULTRA LOW VOLUME (less than: 50 lt/ha - 5 usg/acre)

of chemicals dissolved in water or oil without nozzles or discs needing to be replaced and with umiform coverage (mist droplets from 50 to 150 micron) at unchanged pressure (1,5 bar - 22 psi). This top performance and versatility can only be achieved by the Martignani system, despite the various attempts made to imitate it. Its special design is based on technical know-how acquired during over 50 years pratical experience and research carried out with the best ranking Agricultural Institutes in EUROPE - NORTH and SOUTH AMERICA - SOUTH AFRICA and AUSTRALIA.

MARTIGNANI System Basic Principle

Fig. 1 represents a cube, 300 µ long, wide and high (1 µ = 0.001 mm) plus another 50 µ at the side. The big cube is then divided along its length, width and height into six equal pieces to produce 6 x 6 x 6 = 216 cubes of 50 µ. The ratio applies not only to the division of cubes, but also to spheres, i.e. droplets. The big cube is comparable to the average size of the droplets formed by a high pressure spraying machine, and the small cube with those of the mistblower. From one drop of 300 µ, which is the average size droplet produced by a high volume machine, 216 droplets of 50 µ are produced by the mistblower and millions of such droplets are produced from a pint of water. A 100 µ zone has been drawn around each droplet. This is the zone in which the sprayed chemical is active, see Fig. 2. If you compare the area covered, you can see that the 216 droplets from the mistblower protect a much larger area than the one 300 µ drop from the high pressure sprayer, see Fig. 3. This is the main reason why a mistblower can give adequate coverage with sprayed chemicals and yet use only a small quantity of water. This allows 30 to 50% spray economy to be achieved as compared with dilute spraying, while only 10 to 20% of the water is required.
