Provine Helicopters owns eleven turbine-powered helicopters including eight JetRangers, one LongRanger and two Hueys.
Each of our nine spray helicopters are fitted with double flow Microfoil booms for equalized pressure. The booms are fitted with Accuflow nozzles that allow us to customize the orfice size to accommodate different spray jobs. Each nozzle has an array of 32 needle outlets in a circular configuration. Our system operates with 20 psi boom pressure and under 5 psi nozzle pressure. This boom/nozzle combination produces droplet sizes of 1000 - 1500 microns, depending on which orifice we are using.
Provine Helicopters disassembles all of our booms at the end of each season and bench tests every nozzle under operating pressure. These tests help us ensure the uniformity essential to a good application. Because our boom/nozzle configuration creates such a uniform droplet size, we have better control of the spray and can fly in higher winds.
Our ground support fleet consists of 11 tandem axle nurse trucks with landing platforms, jet fuel tanks, water tanks and mixing tanks. In addition, there are 11 pick-up trucks that serve as additional support vehicles.
