INFICON compact leak detector LDS3000 for vacuum leak testing systems enables leak testing of liquid cooling components such as QDCs. The LDS3000 can be used for both end-of-line testing and testing in earlier production phases. The device works according to the helium vacuum method. It detects helium tracer gas escaping from leaks in the test object into a vacuum test chamber. The smallest detectable leak rate is in the range of E-12 mbar∙l/s. With such small leak sizes, not only the liquid tightness but also the gas tightness of a component is guaranteed. The compact LDS3000 leak detector from Inficon is characterised by its particularly high sensitivity and reliability. It also enables a very high throughput at the leak testing stations in the production line – testing is carried out synchronously with production.

The XL3000flex industrial sniffer leak detector from Inficon detects the smallest leak rates down to 2xE-7 mbar∙l/s. However, as a sniffer leak detector, it does not require a vacuum chamber. The test gas is drawn in by the flow through the sniffer tip which can be guided manually or automatically by a robot arm over the component. The XL3000flex can use either helium or hydrogen as the test gas – more specifically, a non-flammable mixture of 5% hydrogen and 95% nitrogen, also known as forming gas. The XL3000flex is equipped with a high gas flow rate of 3000 sccm, which is indispensable, especially for hard-to-reach leak spots or when using robots that pass by a potential leak spot at high speed. Sniffer testing with the XL3000flex can be used in the production line instead of the vacuum method with the LDS3000. In addition, the XL3000flex is suitable for rework: it can be used to locate the exact position of leaks on parts that have failed a previous integral leak test.

Only such careful leak testing on the production line can ensure that the handling advantages offered by quick disconnect couplings in liquid cooling systems do not ultimately come at the price of an increased risk of potentially catastrophic fluid leaks in the data centre. At their stand J110, Inficon experts will be happy to advise visitors to Data Centre World on all questions relating to the leak tightness requirements of their cooling systems – from liquid to immersion cooling – and explain how this leak tightness can be ensured with reliable, test gas-based testing methods.

About INFICON
INFICON GmbH in Cologne is one of the world's leading developers, manufacturers and suppliers of instruments and equipment for leak testing. The leak detectors are used in demanding industrial processes in production and quality control and cover a wide range of applications. INFICON's main customers are manufacturers and service companies of air conditioning and refrigeration equipment, the automotive and automotive supply industry, the semiconductor industry and manufacturers of leak testing equipment. Almost all manufacturers of refrigeration and air conditioning equipment and their suppliers are among its customers. INFICON technology is used, for example, to test refrigerators, air conditioning systems and their components, heat pumps, drinking water dispensers, hot water storage tanks and gas boilers for hot water production or heating.

Embedded in the INFICON holding company based in Switzerland, the company uses essential components from its own production for its devices, such as mass spectrometers and vacuum gauges. In 2006, INFICON revolutionised leak detection technology with tracer gas through its patented INFICON Wise Technology^TM. In 2011, INFICON acquired the hydrogen leak detection business (the former Sensistor business unit) from Pfeiffer-Vacuum.

INFICON now has more than 50 years of experience in leak detection technology. INFICON handles global sales through production facilities in Cologne (Germany), Balzers (Liechtenstein), Linköping (Sweden), Syracuse (USA) and Shanghai (China), as well as sales offices in all major industrialised countries and an extensive network of sales partners. In fiscal year 2024, INFICON AG achieved global sales of USD 671 million with more than 1,600 employees. INFICON's registered shares (IFCN) are traded on the SIX Swiss Exchange.
