Filling and testing in the automotive industry

In every modern automobile there are a number of components which function on the basis of fluids. All these fluid systems need to be filled and tested in the final assembly of the automobile production. This is the job of Sterling SAT. For over 30 years the company is a successful player in systems engineering for the process industry and develops customer specific systems based on vacuum and compressor technologies. For instance, SAT offers systems for automatic filling of the various fluid systems of a vehicle and thus guarantees the economical and environment-friendly filling of brake systems, power steering systems, gears, cooling systems and air condition systems, as well as fuel systems. These systems are used worldwide by all well-known automotive manufacturers.


Thereby Sterling SAT products minimise waste production and strictly adhere to environmental requirements. In case of exchange or repair of components, the contained fluids can be purified and recovered. Customer specific membrane systems moreover enable efficient treatment of gases and vapours which are a by-product of the process industry.


Total Quality Assurance (TQA) has the greatest significance in the automotive industry. That is why Sterling SAT has developed a series of reliable, high-precision testing devices. An innovative leakage tester from SAT is able to detect leaks in air conditions already in the assembly process and exclude ecological and economical disadvantages beforehand.


As part of the Sterling Fluid Systems Group, Sterling SAT offers a global customer service network which is unparalleled in the industry.
