Automatic leakage detection for Pet bottles
Ensure the integrity of bottled beverages by detecting even the smallest leaks and closure faults automatically, safeguarding product quality and packaging stability in high-speed production environments.

Detects Leaks and Inspects Closures
The HEUFT Squeezer II from HEUFT SYSTEMTECHNIK GMBH is an in-line PET bottle leak detection system designed specifically for beverage, food, and pharmaceutical manufacturers. This equipment excels in ensuring product integrity by employing a comparative fill level detection and internal pressure measurement to identify leaks, stress cracks, and microcracks in containers. Its fully automatic operation is facilitated by the HEUFT SPECTRUM II platform, which adapts seamlessly to brand and format changes without manual intervention.
Capable of handling up to 72,000 bottles per hour, the HEUFT Squeezer II integrates advanced closure inspection technologies, including sensors, cameras, and ultrasonic tools, to verify closure integrity, thereby safeguarding the tightness and quality of drinks packaging. This system supports continuous operation and networked inspection solutions with real-time monitoring and data acquisition, enhancing line efficiency and reducing waste through precise fault rejection using the HEUFT rejector series.
The equipment’s robust design, optimized for hygiene, includes HEUFT Clean Design features for easy cleaning in sensitive environments, ensuring compliance with stringent hygiene standards. Customizable with various detection technologies, such as high-frequency and X-ray, the HEUFT Squeezer II provides versatile inspection capabilities tailored to specific production needs, complemented by intuitive HEUFT NaVi user guidance for simplified operation and troubleshooting.
