The very latest technology and safety: In the very best BAUER quality
Spatially optimised for wherever space is at a premium: Compact, modular design and powerful with housing made from concrete or steel for sound insulation and weather protection
Global spare parts guarantee over 25 years: Your investment could not enjoy better protection
On-site installation and commissioning by experts: Our experienced specialists and engineers will attend your site to carry out this work
The basic version of the CS 23 – CS 52 is designed for operation with one compressor and a storage system. It is ideal for busy public filling stations with a high daily capacity of more than 200 passenger cars/day or 20 HGV/day.
If the number of vehicles to be serviced daily increases, a second compressor can easily be added to the station (which is available in two different designs) and – should refuelling peaks rise – a second storage module.
Its technical benefits (drying on the high-pressure side and monitoring of the pressure dew-point) are also undisputed.
Thanks to the quality that is synonymous with the BAUER name, the filling station can be depended upon for reliable operation at all times, even under maximum stress and load. Furthermore, long service life and spare parts availability (25 years) provide your investment with the very best protection.
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.
