Leak testing of liquid coolers – technologies, service & quality
Every liquid cooler is tested for leaks to ensure the system’s safety, reliability, and efficiency. Depending on the requirements, different testing methods are used – from standard tests to highly precise helium leak tests.

Bubble Leak Test
The bubble leak test is a simple yet effective method for detecting leaks.
Process:
-
The part to be tested is coated with a soap solution.
-
Pressure is applied to the component.
-
Bubbles form at leak points that must be repaired.
-
Ideal for weld seams and seals
-
Cost-effective and fast
-
Applicable in food, pharmaceutical, and automotive industries
Pressure Drop Test
The pressure drop test checks tightness by monitoring a defined pressure over a set period of time.
Process:
-
A pressure level is established in a closed system
-
The pressure is continuously monitored
-
If the pressure drops, this indicates leaks
-
Reliable and precise
-
Early detection of leaks
-
Suitable for cooling systems and pipelines
Helium Leak Test
The helium leak test is a high-precision method for liquid coolers that can detect even the smallest leaks.
Process:
-
The cooler is filled or surrounded with helium
-
A special detector identifies even minimal gas quantities
-
Highest accuracy
-
Detects microscopic leaks
-
Ensures safety and functionality
Why leak testing and part cleaning are essential
The leak test is a key step in detecting leaks early, ensuring operational safety, and avoiding unnecessary costs. Only products that pass this test meet the highest quality standards, which also increases customer satisfaction.
Part cleaning is equally important. During production, dust, oils, greases, or machining residues can remain on surfaces, reducing thermal conductivity and performance. Using modern processes such as ultrasonic cleaning, chemical baths, or high-pressure rinsing, these residues are reliably removed. Especially for liquid coolers with fine internal channels, thorough cleaning prevents blockages and ensures a free coolant flow.
The combination of precise leak testing and careful cleaning ensures that your cooling systems operate efficiently, remain reliable, and achieve maximum service life.
Absolute tightness for maximum safety
Our precise testing methods ensure your liquid coolers are completely leak-free and reliable. Every leak is detected early for maximum quality and safety.
