SPEEDFLOW PROGRESS
Air speed, precision and flexibility
SPEEDFLOW 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 SPEEDFLOW PROGRESS 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.
For row widths from 1.50 to 3m, the Speedflow Progress, a pneumatic "face by face" rail with 2 or 3 complete rows, is equipped with the FLEXIspray system: lightweight, flexible and unbreakable boom sprayers, inflated by air distributed uniformly by a polyethylene volute with 6 outlets and expelled by a turbine 520mm in diameter, which renders them rigid and positions them vertically within the row. The DynaDiff diffuser nozzles increase the air speed, ensuring the product is perfectly distributed, droplet formation is optimised, and the spraying quality is excellent.
FLEXYSPRAY
FLEXYSPRAY is a boom sprayer exclusive to GREGOIRE. Flexible, it is inflated by the air expelled by the turbine, which makes it rigid and vertical inside the row. It moves when it encounters an impact, returning to its original shape, thereby limiting breakage. Its low weight reduces the strain on the boom.
DYNADIFF 3D
Rotative diffusers, 360° product spectrum orientation. Increasing the air speed, DYNAdiff 3D gives better distribution of the product and perfect droplet formation, providing significant agitation of the plant canopy to ensure optimum penetration of the product, with limited drift.
EASYselect
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.
SPEEDFLOW
SPEEDFLOW groups together all of GREGOIRE's pneumatic sprayers. This spraying principle is recognised for its precision and efficiency, whilst limiting drift of the product. GREGOIRE has 6 different booms available in this range, to ensure there is one perfect for every vineyard.
Homologation Routiére
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.
