GLOBALTEK® Fill-It In-Line Automatic Bottle Filling Machine with Pressure Overflow System

The GLOBALTEK® Automatic Overflow Fill-It is a specialized automatic bottle-filling machine designed to fill every container to the same level, regardless of the internal volume of each bottle. This bottle-filling machine uses a nozzle that overflows the liquid into a holding tank once the desired fill level is reached. The liquid filling machine utilizes advanced indexing and a PLC system, enabling continuous bottle filling without manual operation during each cycle.

Main Features:

• 304 Stainless steel and anodized aluminum heavy duty frame fully enclosed with stainless steel panels.
• 20 Gallon stainless steel covered overflow tank with level sensor and sanitary fittings.
• 304 stainless steel feeding 3A certified manifold with clear PVC hoses.
• Mounted on four heavy duty threaded leveling pads
• Variable speed control for conveyor
• Pump speed, acceleration, and deceleration is controlled by a frequency drive.
• Front panel start and emergency stop

How an Automatic Bottle Filling Machine Works

Automatic overflow filling controls fill height rather than volume. Bottles are precisely indexed beneath the nozzles; product flows until it reaches the set level, then any excess returns to the recirculation tank. The result is a consistent visual level across bottles—even when internal volumes vary. This method is ideal for clear containers and free-flowing, non-particulate liquids where shelf appearance matters. Proper nozzle submergence and dialed-in ramp profiles minimize foam, while stored PLC/HMI recipes keep changeovers fast and repeatable.

Overflow vs. Volumetric Filling: Pros & Cons

Overflow (Level-Fill)

• Pros: Identical visual fill height in transparent bottles; fast changeovers; recirculation reduces waste.

• Cons: Controls level—not exact mL/oz—so it’s less suited to higher viscosity or particulate products.

Volumetric (Piston / Flow-Meter)

• Pros: Delivers precise volume per container; better for viscous or particulate applications.

• Cons: Fill height can vary with bottle tolerances; cleanouts and change parts may require additional time.

Quick guidance: Choose overflow when a uniform shelf appearance is the priority. Choose volumetric when labeled volume accuracy is the governing requirement.

Maintenance Checklist for Your Bottle Filling Machine

Daily

• Flush the product path; confirm overflow/return is clear.

• Inspect nozzles for residue; verify no-bottle/no-fill and downstream back-pressure sensors.

• Check indexing gates and neck guides for alignment; test the emergency stop.

Weekly

• Inspect hoses, clamps, and sanitary connections for wear/leaks.

• Verify conveyor timing relative to nozzle up/down motion; review key HMI recipes.

Monthly

• Lubricate linear guides and bearings per spec.

• Inspect pneumatic components and drain air filters; confirm repeatable stroke.

• Validate pump VFD acceleration/deceleration to control surge and foam.

Quarterly

• Perform full CIP/SIP as applicable; replace worn gaskets and O-rings.

• Audit guards and fasteners; back up current PLC/HMI parameters.
