Leakage Laboratory

Determining Refrigerant Leakage Rates

As a technical service designated by the KBA, we carry out leakage measurements on automotive air conditioning systems and their components. We have the most modern test equipment for determining the leakage rates of all common refrigerants. For this purpose, we have test chambers for hoses, fittings and components. In addition, measurements can be carried out on complete systems, which are set up true to the original in our test chambers.

Certified by the Federal Motor Transport Authority

We are one of the few companies in Europe accredited by the Federal Motor Transport Authority as a test laboratory for determining R134a leakage rates. The accreditation was granted on 20.12.2007 and was valid until October 2018, authorising the company to carry out leakage measurements in accordance with Directive 2006/40/EC including Regulation 706/2007 on motor vehicle air conditioning systems and their components as part of the KBA type approval. Since 2017, this type approval is no longer required by the KBA with regard to air conditioning systems, as in Europe only new registrations of vehicles with a refrigerant with a global warming potential (GWP) <150 are permitted.

  • Geodetic set-up of the air-conditioning system on site in the test laboratory

Environmental protection first and foremost

We stand for environmental protection. Partially fluorinating greenhouse gases have not yet been completely eliminated, as vehicles with the refrigerant R134a are still on the roads. Here, too, it is important to keep the leakage rates of components as low as possible and to reduce the GWP, for example, by using refrigerant mixtures.

Highest Level of Quality since 2017

We have been operating the leakage laboratory since 2017 in order to constantly drive improvements in sealing concepts in the field of air conditioning and to detect faulty components at an early stage before they go into series production at the car manufacturer. In this way, we make a decisive contribution to ensuring a high level of quality in air conditioning systems.
