SPEEDFLOW PROGRESS
Air speed, precision and versatility
GREGOIRE SPEEDFLOW range is built around a lightweight yet robust tubular chassis designed for durability and ease of use. Its centrally positioned axle, adjustable to match the tractor track width, ensures excellent weight distribution and stability.
A steering drawbar mounted on bearings greatly enhances manoeuvrability, even in tight headlands.
GREGOIRE SPEEDFLOW PROGRESS ZNT features a smooth polyethylene tank that preserves the canopy structure. The main tank integrates a rinse tank and a hand-wash tank for increased operator convenience.
Several tank capacities are available to perfectly match each vineyard’s requirements.
The spraying circuit on GREGOIRE SPEEDFLOW PROGRESS ZNT has been carefully engineered to ensure reliability, accuracy and constant flow:
-
The mixture enters through an induction hopper before passing through a low-pressure filter.
-
A high-performance 4-piston diaphragm pump provides optimal feed and effective agitation.
-
A high-pressure filter ensures clean and consistent delivery to the regulation and distribution boom.
Depending on the configuration, GREGOIRE SPEEDFLOW PROGRESS ZNT may feature:
-
DPAE automatic rate control for fully automated product application, or
-
Manual regulation for simplified, cost-effective operation.
Designed for vine spacing from 1.50 to 3.00 m, GREGOIRE SPEEDFLOW PROGRESS ZNT is a face-by-face pneumatic sprayer available in 2- or 3-row configurations.
It incorporates the patented FLEXIspray system, consisting of:
-
Flexible, unbreakable, ultra-light pendillars
-
Inflated by a perfectly even airflow supplied by a 6-outlet polyethylene volute and driven by a 520 mm turbine
-
Once inflated, pendillars become rigid and remain vertically aligned inside the canopy for optimal coverage
Spray quality is enhanced by Dynadiff diffusers, which:
-
Increase airspeed
-
Improve droplet formation (micronisation)
-
Ensure perfectly even distribution across the vegetation
GREGOIRE SPEEDFLOW PROGRESS ZNT guarantees exceptional spray penetration, reduced drift and optimal product efficiency.
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.
