The compact and expandable station has been dimensioned for the most exacting safety standards and in particular for large depots and public filling stations with a daily capacity of up to 200 passenger cars/day or 20 HGV/day.
Its outstanding quality, uncompromising safety standards and impressive design and innovation solutions "Made by BAUER" are the key to ensuring that modern filling stations can be relied upon at all times, even under peak load.
Furthermore, very long service life and optimum spare parts availability (over 25 years) provide your investment with the very best protection.
The basic version of the CFS DUO is designed for entry-level operation with one compressor and a storage system.
If the number of vehicles to be serviced daily increases, a second compressor (DUO II) can easily be added to the station and – should refuelling peaks rise – a second storage rack.
With its clear modular structure, this CFS station from the DUO series can be equipped initially with a compressor of the appropriate size for the individual application concerned.
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 During refuelling, it also regulates the sequence in which gas is withdrawn from the high-pressure storage system.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.
