The Pull-type Engine Driven Whirlwind M612 Sprayers are to be driven by a 90 HP (or above) independent engine. Therefore, the tractor used must simply pull the equipment. They have been specifically designed to solve problems related to treatments on extensive outsize plantations of "fruit-tree or row crops" and in particular on Citrus plantations, Olive plantations, Walnuts, Almonds, Tropical row crops such as: Mango, Pawpaw/Papaya, etc. or where tractors of adequate power are not available.
Centrifugal fansof special design and exceptional efficiency, producing large volumes of air and remarkably high air flow rate at very low rev number and absorbed power.
Spray nozzles(patented - with special profile and large - 4 mm. - diametre), thus no clogging, no jamming, no wear, no deformation. They are situated in the point where the air stream reaches a speed of up to 300 KPH and thus divide the liquid flow into extremely fine and even droplets.
Stainless steel high precision metering valves(patented): the output of liquid can be easily changed from 50 to 1300 I/h each; depending on the quantity (or volume) of fluid to be sprayed per hectare or acre, according to the desired tractor speed, concentration of chemicals (from normal to 2,3,4. . . 10. . .20 times), soil conditions, density of foliage, etc.
Low pressure, high delivery self priming centrifugal pumpmade in stainless steel for nozzle feed - adjustable, continuous agitation of the spray fluid, rapid, non polluting self-filling. It also powers the large capacity.
Pre-mix-eco attachment, ideal for preparing chemical mixtures in a closed tank, both during self-filling and when the tank is already full, by simply operating a valve.
Italian Quality Tank, made of reinforced polyester resin or POLY for 3P hitch and pull-type models all featuring two built-in tanks for circuit rinsing and hand wash each; made of stainless steel for engine driven models and the 2000 l (500 gal.) PTO one (rinsing and hand wash tanks are on request). The suction sumps are specially designed to assure thorough spraying even when operating on sloping grounds. The level of the liquid is clearly visible in the tank side.
The suction filteris external and it can be easily cleaned even when the tank is full. Sturdy, oversized frames of hot galvanised steel profile with adjustable drawbar, support feet, adjustable axles. All p.t.o. models are perfectly balanced (center of gravity on the axle) thus very manoeuvrable when empty; in operation, 50% of the useful load advantageously rests on the tractor’s hind-wheels.
Remote control unitwithin driver’s reach; equipped with glycerine pressure gauge and calibrating valve, delivering the fluid to the spray heads individually. On request: spray computer.
• ELECTROSTATIC SPRAY SYSTEM •
The Martignani Electrostatic Spray System can REDUCE LOSSES THROUGH DRIFTING by 85%. It is the first of it's kind to be produced in Europe (1981) & the only one that has been thoroughly tested in several counties with evidence based, phyto-therapeutic results.
How it works
Thanks to the electrostatic fields formed between the plants, (sap, mineral salts, moisture, etc.) and the chemical mist that is sprayed from a Martignani Electrostatic Sprayer, with their special electrostatic charge, droplets that are saturated with the active principle are attracted by the vegetation (branches, leaves, etc.). Thus, dramatically reducing losses through drifting, even in windy weather.
Less loss through drifting.
Total use of the pesticide, thus even less product required per hectare.
Total coverage of even the tallest parts of the trees (where conventional mist-blowers are unable to reach) since the chemical mist that forms above the plants is attracted by these latter.
Jobs are done faster (up to 12 Km/hour).
More time saved.
Healthier plants and better quality produce.
A notable reduction in environmental pollution.
The lower risk of the operator being contaminated by pesticides (both by inhalation and by contact) is reduced by 70%.
