POWERFLOW sprayers comprise a lightweight tubular chassis which is both simple and robust. The axles, which are positioned centrally and can be adjusted to the tractor's track width, offer excellent load distribution. The articulated drawbar, fitted on a bearing, improves handling. The POWERFLOW TTA is equipped with a smooth polyethylene tank to prevent damage to the vines. The rinsing tank and the hand wash reservoir are integrated into the main tank. This range is available with a choice of tank capacities to satisfy your requirements.
The spray product follows a circuit carefully designed and optimised by our developers. You add the product to a mixer screen which is then fed through a low pressure filter. It is circulated by a four-piston diaphragm pump with a sufficient capacity to ensure optimum priming of the circuit and efficient mixing. It is then conveyed to the regulation and distribution rail via a high pressure filter. The regulation and distribution controls vary according to the model: DPAE flow regulator for automatic management of the product amount, or manual regulation.
The POWERFLOW TTA enables you to treat 4 complete rows. The working speed is steady, and the cost per hectare reduced. Three turbines, 750mm in diameter, with an inverted air intake system to prevent any recirculation of products or pick-up of debris. Stainless flaps support twin-jet diffusers tilted 30° backwards to help penetration of the product. A powerful air flow is provided by the DX'PLUS vertical tower and adjustable flaps can be oriented for precise positioning. The POWERFLOW TTA is the perfect sprayer for large heavily trained vineyards.
Dx'Plus is a tower with a specific design. It enables air to flow uniformly, and the product to be mixed perfectly. Twin-jet diffusers on stainless flaps tilted 30° backwards also allow optimum penetration of the product into the plant canopy.
EASYselect is a centralisation device for the valves supplying your sprayer. It controls the external mixer, the rinsing nozzle, the stainless container rinsing screen, the cleaning lance and hydro-injectors to simplify cleaning of your equipment.
POWERFLOW groups together all of GREGOIRE's aero-convection sprayers. This spraying principle combines simplicity with efficiency and high working speeds. It is available with 5 different towers or turbines, to ensure it can be adapted to suit every vineyard.
All sprayers in the GREGOIRE range have been approved since 2011. This relates to all trailed models with a GVW of over 1500 Kg. In force since 1st January 2013, this French regulation stipulates that an application must be made to the DREAL to obtain the registration certificate.
