Droplet uniformity of M3 atomizers is highlighted in Brazilian market

Zanoni atomizers with M3 mesh have received praise from pilots and agronomists due to the uniformity of drops offered by the equipment

It took us a while to enter the rotary atomizer market, as we lacked agronomic knowledge on the subject, and we started manufacturing the atomizers only a few seasons ago, at the request of some of our partners who complained about problems related to this type of equipment here in Brazil. After a few years of working in the field together with operators, the Zanoni rotary atomizer has been gradually improved to offer an accurate and efficient application for the agricultural pilot, seeking to offer a wide spectrum of droplet sizes in the most uniform way.

Constantly seeking to improve the equipment and listening to several complaints about the lack of uniformity in spraying (including about the first prototypes of our own rotary atomizers), we have endeavored to offer the most efficient atomizer in terms of droplet size distribution. Their uniformity is measured by the relative sapn (RS), an important indicator for the quality of the applications, which affects both their biological efficiency and the drift potential. The more uniform the spectrum, the smaller its relative span.

Zanoni rotary atomizers with M3 mesh have received several positive comments on this topic.

In a test carried out by Rodrigo Franco Dias (UFSM, ConnectFarm) on an Air Tractor aircraft (with an average speed of 140 mph) spraying water, very appropriate relative spans were found, according to the parameters indicated by agronomists specialized in this area. The research conducted in Rio Grande do Sul analyzed the droplet spectrum based on three flow rates (5L/ Ha; 10L/ Ha; and 15L/ Ha) under 3 types of different equipment settings (high, medium and low rotation). Offering a Volume Median Diameter (VMD) between 130µm and 200µm (depending on the desired calibration), the rotary atomizers presented the following relative spans:

Now in September, the same equipment model was featured in the magazine AgAir. Tests with Zanoni M3 rotary were carried out by Alan McCracken in an AT402 of Grupo Piaia, in Piauí (Brazil). The renowned agronomist, author of this month's cover story in the magazine, points out that there was "an almost perfect distribution of drop sizes for insecticides and fungicides using low volumes, with a minimum drop volume below 150 microns and a low percentage above ideal maximum of 350 microns". In addition to the article published in the magazine, the expert sent us a compliment regarding the uniformity of drops presented by the equipment and also for the quality of the variable restrictor unit (VRU).

The two tests, thus, confirm the experiences reported by our partners, that the Zanoni rotary atomizer have shown a standard of excellence in relation to the uniformity of drops, with the traditional durability of our equipment.

Even with results already quite satisfactory in terms of durability and efficiency, we continue to seek to improve our rotary atomizers. More recently, we also launched the M14 mesh, which will provide another type of droplet spectrum to the agricultural pilot. Some tests have already been carried out, others are scheduled and the results will be available soon.

We thank each of our partners who were and are still involved in the development of the Zanoni rotary atomizer and place their trust in our work. We reinforce that our doors are always open to listen to your problems, your new challenges and also the criticisms and suggestions for improving our equipment and services.
