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
• Automatic tool-less neck guides included as standard to prevent spillage
• Automatic tool-less bottle indexing gates to control container travel (entry and exit)
• Tool-less nozzle mount adjustment (0 to 4 inches)

In-Stock with Pre-Shipment Requirements

While this machine is currently in stock, shipment is subject to completion of required pre-shipment activities, including sample evaluation, machine configuration to your specifications, Factory Acceptance Testing (FAT), and setup. These activities generally require approximately 10–12 weeks from the date we receive representative samples. After these steps are concluded, the machine will be crated and prepared for shipment.

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.
