Leak Detection

We provide Leak Detection services via many proven techniques.

Leakage check with pressure test.
The primary side is filled under pressure with air or water. The secondary side is pressure free. On a plate defect, there's a pressure reduction on primary side.

Leakage check with conuctometry test.
The primary side is filled e.g. with sodium sulfate. The secondary side with water. Driven by the osmotic differential pressure the tracer substance diffuses on the water side .

Leakage check with infiltration UV -tracer.
The surface of the plates must be chemically cleaned. Then a fluorescent color is up-sprayed. After a response time each plate is checked with UV light in a darkened area.
