ROTOFILL P-ECO – Semi-automatic rotary liquid filling machine
Filling of liquids and more or less viscous products with pneumatic volumetric dosing, HMI control and cap tightening station.
Overview
ROTOFILL P-ECO is a semi-automatic rotary filling machine, with electro-pneumatic operation, designed to handle a wide range of products: from water to oils, creams and gels.
The project comes from the combination of proven solutions developed over time: a robust mechanical base derived from models historically used in production and an integrated dosing unit PACK ECO. The result is a compact and practical filler, designed for those who want productivity and simple operation without unnecessary automation.
To improve cycle control and repeatability, the machine includes an electrical cabinet with a touchscreen HMI panel: the operator precisely manages pneumatic solenoid valves, station movements and process settings.
Operating note: actual output depends on volume and viscosity, cap tightening time, and how quickly the operator places the cap (manual cap placing).
Ideal for
- Filling of liquids (e.g. water) and semi-dense products (oils, creams, gels)
- Production runs requiring quick changeover and simple operation
- Lines where filling + cap tightening are needed in a single machine
Key strengths – semi-automatic rotary liquid filling machine ROTOFILL P-ECO
1) Versatile pneumatic volumetric dosing
Dosing unit designed to cover multiple ranges, suitable for products with different viscosities, with a simple and robust adjustment logic.
2) HMI control for a more stable cycle
The touchscreen enables orderly management of the electro-pneumatic cycle and movements, reducing “by feel” interventions and increasing repeatability.
3) Capper with quick-release chuck
Capper changeover in seconds thanks to the quick-release chuck: less downtime, more continuity in production.
Technical details
Rotary table + integrated conveyors
The machine integrates a variable-speed conveyor (inverter) that feeds empty packaging to the rotary table and conveys the finished product to the outfeed.
Manual cap placing (and automatic alternative)
After filling, the rotary table brings the packaging to the cap placing station: on ROTOFILL P-ECO the operation is manual.
If you want to automate this phase as well, the reference solution is ROTOFILL PRST, with a dedicated pick & place.
Cap tightening with pneumatic vane motor
The capper uses a pneumatic vane motor: a suitable choice when looking for compactness, light weight and durability and, where required, when the application must remain compatible with ATEX certification logic.
Torque is conveniently adjusted via a pressure regulator.
Optional: heated hopper
For more viscous products, the optional heated hopper with PID temperature controller is available, designed to stabilize viscosity and simplify the filling process.
Supported packaging
- Bottles / containers with a stable base
- Jars
Not recommended for very slim and tall containers with an unstable base (e.g. mascara/lip gloss formats).
Technical FAQ
Liquids and more or less viscous products: water, oils, creams and gels (final evaluation always depends on viscosity and product behavior).
No: it is semi-automatic. Cap placing is manual; cap tightening is integrated.
In a simple way: by adjusting air pressure via a dedicated regulator.
Yes: if you need automation also for cap placing, the solution is the ROTOFILL PRST model with pick & place.
It is a maximum value: actual output depends on volume and viscosity, cap tightening time, and the operator’s pace in placing the cap.
It is recommended when viscosity makes filling unstable/slow: PID heating helps stabilize the process.
