Benelabo’s spray system covers 7 series and 36 gun models for fluid bed granulation, Wurster bottom-spray coating, tangential and centrifugal pelletizing, high-efficiency tablet coating, wet granulation and CIP cleaning — spanning machines from 1 L lab beds to 300 L+ production coaters. Standard nozzle bores run φ0.6–1.2 mm, and air caps, liquid lanes and body geometry are engineered to your liquid properties rather than picked from a catalog. Every gun body is CFD-simulated before machining and laser-tested for atomization uniformity before shipment. The core promise is retrofit: a matched gun set upgrades the spray performance of your existing fluid bed or coater without changing its mechanical structure or control program. Send your machine model, process and liquid — the configuration comes back sized, verifiable in a sampling test before you commit.
The Seven Gun Series
| Series | Process | Models |
|---|---|---|
| Top Spray Gun | Fluid bed top-spray granulation and drying | 10 |
| Bottom Spray Gun (Wurster) | Pellet and particle bottom-spray coating | 6 |
| Tangential Spray Gun | Centrifugal pelletizing and tangential spray | 5 |
| Coating Spray Gun | High-efficiency tablet coaters | 5 |
| Wet Granulation Spray Gun | Binder addition in wet granulators | 6 |
| Centrifugal Pelleting Gun | Multifunction machine centrifugal pelleting | 2 |
| Cleaning Ball (CIP) | In-place equipment cleaning | 2 |
Plus the Hot Melt Spray Coating System for solvent-free functional films — heated tank, heated line and thermostatic gun as a retrofit set or paired with a turnkey fluid bed tier.
Gun Families
Core Capabilities
- Custom nozzles, not catalog-only: bores φ0.6–1.2 mm standard, air caps and geometry customized to your liquid properties
- Retrofit without machine replacement: gun plus liquid/air adaptation upgrades spray uniformity on existing machines — no control program changes
- CFD-verified atomization: spray field simulation drives body and air-cap design before any metal is cut
- Laser-tested before shipment: every gun’s atomization pattern is verified against its specification
- Fully detachable, no-weld bodies: clean-room-grade construction, fast disassembly for inspection and cleaning
How to Choose
Tell us your machine model or bowl size, the process (granulation, coating, pelletizing) and the liquid — we return a gun configuration with nozzle sizes and air-cap selection, verifiable by a sampling test before you commit. For scale-up, the same nozzle family is available across lab, pilot and production bowl sizes, so parameters transfer instead of being re-invented.
