Leakage detection for beverage cans
Ensure each canned beverage leaves your facility ready to impress, with precise leak detection measuring internal pressure without contact.

Detects Leaks in Beverage Cans
The Checkmat SLD from Krones is a sophisticated leakage detection system designed for the beverage industry. What sets this equipment apart is its contact-free operation using a 3D laser scanning process to accurately detect leaks in beverage cans. By projecting a fanned-out laser beam onto each can and capturing the lid’s bulge profile, it reliably assesses internal pressure without halting your production line. This method ensures continuous, high-speed operation without wear-related downtime and eliminates the need for physical contact, thus maintaining the cans’ integrity. Ideal for dynamic food and beverage environments, the Checkmat SLD is beneficial for applications involving soda, juice, spirits, milk, and water. With a focus on efficiency and integration, it requires a corresponding layout drawing of the filling line, with pressure usually stabilizing around 30 minutes post-filling. This unit streamlines quality assurance, ensuring only perfectly sealed cans proceed down the line, effectively reducing waste and safeguarding product quality.
