The HARDI TWIN has been tested at Flakkebjerg/Aarhus University Denmark over a two year period from 2017 and 2018.
The purpose of the test was to monitor the difference on deposits under the boom and the drift besides the boom using conventional and TWIN air assistance spraying Technics.
Spray deposition and spray drift from applications at two wind speeds were tested at 8 and 12 km/h with conventional technique and at 8, 12 and 16 km/h with TWIN air-assistance.

A 24 meter trailed Hardi TWIN sprayer equipped with LD-025 nozzles at 3 bar pressure was used in the test.

In the report there is a number of interesting  findings

The advantages of TWIN FORCE air-assistance showing that spraying speeds from 8 to 12 km/h and high wind speeds are not causing problems for the quality of the application.
