Overview

Locating and repairing of gas or liquid leakage or air can increase safety and productivity of you plant. Tube leaks can cause outages and consequently loss of production. Therefore, it is essential that your plant or processes are equipped with advanced tracer detection technology, so that the technicians can quickly locate any sources of leaks and eliminate the problem. At HYB we have vast experience with ensuring tightness of pharmaceutical packaging.
Leak detection can be performed for various substances, such as smoke, gas, fog, liquid, or for verification of a tightness of a seal, especially in food, medical or pharmaceutical sectors. Leakage can be measured based on various physical parameters, such as pressure sensing, vacuum, etc..

Leak Detectors at HYB

At HYB we developed a vacuum controller and Exicator (VK 100 + E 200) which is ideal for checking leakage of packed strips, blisters, small sachets of tablets, capsules, liquids, cough syrups, shampoo packets, ampoules, sutures etc. HYB has also obtained the certificate of compliance with the standard required for medical products.

HYB Leakage Detection

The HYB testing device is based exclusively on a destructive method of testing of blister tightness. It works of the principle of establishing controlled vacuum and atmospheric pressure. Based on the preset times of pressure states, blister leakage can be defined. Leakage can be visually observed after the cycle termination as colored blister contents.

Locating Leakage Sources

In the first step, the test samples are immersed into a coloured medium. The coloured liquid with the submerged samples is in special glass exicator E200 and covered by a sealed plexi-glas cover, connected to the VK100 controller by two tubes. The system is established for an adjustable test time in a vacuum, and then released to atmospheric pressure for the penetration time. In case of punctured blisters, vacuum is transferred to them in the first phase, which in the second step attracts the surrounding medium – namely the coloured liquid. At the end of the cycle, the operator manually pulls the tested samples out to visually evaluate them as good or bad, depending on the colour. It records the results in the VK100 + E200 device which records the results on a storage medium (USB stick).

Leak detectors have an important role in various industrial applications, for example: Food Packaging Leak Detection System (only for small samples, suitable for exiccator), Medicine/Drugs Packaging Leak Detection System, Water Leaking Detection System, Gas Leaking Detection System, Blister Leakage detector or Blister-pack Leakage detector
