Natural gas supply of engine test benches: For the comprehensive testing of engines powered by natural gas under real conditions
The development of engines powered by natural gas necessitates that they are tested extensively under real conditions.
All engine properties can only be tested to the fullest possible extent if continuous operation (including under extreme conditions) can be simulated.
For this reason, BAUER has developed a range of system components specifically for natural gas supply to engine test benches. Whether to supply a single test station or a number of test stations in parallel, for a new test bench or to expand existing test benches, we are able to offer you excellent solutions tailored to meet your needs and in full compliance with local and international regulations.
The natural gas supply is customised so that it fits perfectly into the existing infrastructure and is adapted to meet the actual requirements of the test benches. Natural gas refuelling points with the required final pressure, the corresponding safety infrastructure and data interfaces to the test bench control centre complete this concept for safe gas supply.
All system components (compressors, gas dryers, system controls, storage units and refuelling points, for example) are BAUER KOMPRESSOREN products and are based on our extensive experience and expertise of high-pressure systems dating back many years.
They are perfectly matched to achieve optimum performance when combined and offer our customers 100% BAUER quality, Made in Germany.
All the information you need at your fingertips!
The BAUER compressor blocks have been designed specifically for CNG applications. Exceeding the requirements of all international safety standards, they are characterised by their high energy efficiency and reliability under the most demanding conditions. Read more
High-pressure gas treatment system
The high-pressure gas treatment system (high-pressure filter) is installed downstream of the compressor on the pressure side. Its primary function is to effectively remove excess moisture and possible oil deposits from the natural gas. Read more
Sound insulation and weather protection
The entire unit is integrated inside a housing made from concrete or steel for sound insulation and weather protection.
This provides the best possible protection against the most extreme ambient conditions and, thanks to the use of air handling units or heating systems, can be used in temperature ranges of ±55°C.
Tailored to meet your individual needs, our housings can be fitted with additional important options such as protection against sandstorms.
Filling and refuelling control
Filling and refuelling control regulates the priority in which the high-pressure storage system is filled. During refuelling, it also regulates the sequence in which gas is withdrawn from the high-pressure storage system. Read more
During technical parts approval testing in the factory prior to delivery, the TÜV carries out comprehensive pressure and safety testing as well as testing the electrical equipment.
