MULTIFLOW PROGRESS QUATTRO
Air speed, precision and efficiency
Designed for demanding vineyards and for use with GREGOIRE GM, GL or GX carriers, GREGOIRE MULTIFLOW PROGRESS QUATTRO is engineered to deliver maximum performance in wide-row conditions.
A compact, ergonomic one-piece chassis/tank assembly ensures excellent stability and safety, while allowing fast installation and removal.
The integrated rinse rotary nozzle guarantees easy and efficient tank cleaning, reducing downtime and optimising daily productivity.
This robust design ensures long-lasting durability and reliable operation in even the toughest working environments.
The spray liquid follows a circuit developed and optimised by GREGOIRE’s engineering teams.
• Product introduction through an incorporation sieve
• Passage through a low-pressure filter
• Transfer via a 4-piston diaphragm pump, providing high flow for excellent priming and consistent agitation
• Final filtration through a high-pressure filter before reaching the distribution system
All spraying and regulation functions are controlled from the cab via the i-Monitor touchscreen, integrating:
• DPAE (Automatic Rate Control)
• Headland sequencing
• Intuitive spray management
This smart control system ensures precise application, simplified adjustments, and optimal spray efficiency.
Designed for wide vineyards (1.80 m to 3.00 m) and high foliage density, GREGOIRE MULTIFLOW PROGRESS QUATTRO delivers outstanding spraying performance.
The system features:
• Four 650 mm turbines with reverse airflow technology to prevent re-aspiration of spray or debris
• Stainless steel vanes supporting bi-jet nozzles, tilted 30° rearward for improved canopy penetration
• Vertical air ducts equipped with DX’PLUS technology, generating a powerful, homogeneous and horizontally directed air stream
This combination ensures:
✔ Exceptional product distribution
✔ Uniform coverage across dense vegetation
✔ High spraying efficiency even at elevated forward speeds
GREGOIRE MULTIFLOW PROGRESS QUATTRO is engineered for growers seeking maximum productivity and unmatched application accuracy.
TOOLintegration
With TOOLintegration, GREGOIRE versatile carriers are pre-equipped as standard to be versatile, allowing a GREGOIRE spraying unit or tool to be easily installed. ISOBUS technology allows this equipment to be controlled directly using the existing controls in the cab.
Dx'Plus system
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.
DynaDiff
The DynaDiff outlet increases the air speed to give you better distribution of the product and perfect droplet formation. It provides significant agitation of the plant canopy to ensure optimum penetration of the product. Application is excellent, 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.
