2 A new concept at refueling CNG stations The Aspro SCA-50 compressors concentrate in one single product all the functions of a traditional refuelling station, allowing to compress, store and deliver CNG fast and efficiently. The compact structure and small dimensions make it an ideal solution to build a CNG refuelling station at a low cost. The SCA-50 allows to extend its capacity adding new modules according your fleet needs.

3 A new concept at refueling CNG stations The SCA 50 Aspro series equipment is made up mainly of a horizontal reciprocating compressor, of 2, 3 and 4 compression stages driven by an electric motor and a direct transmission system. Also available in other versions: >Booster that includes a pre-compressor (encapsulated screw unit) driven by independent electric motor. >Variable inlet pressure, that can receive gas from 3,600 to 100 psi connected to CNG transport unit or can be used as standard compressor connected to gas pipeline

9 Due to its technology, flexibility, and better relation cost benefit, this new innovative concept for CNG stations developed by Aspro, is ideal for: Small fleets. Small cities or municipalities. Low volume sale stations. Increase the sales capacity of the Refuelling Station.

10 Benefits Easy installation and start up This compression system can be directly installed in the filling area Simple functioning Having a compressor, storage and dispensers in the same unit makes the SCA-50 an efficient and simple system to operate. Small size Compact and functional structure that allows to improve its transportation, installation, maintenance and the CNG filling process.

11 Benefits Low cost Its low cost and high performance turn it into the right option to install a refuelling station at a low level of investment. Low vibrations levels Aspro has developed a new compressor unit that reduces the vibrations generated in the process of compression below the values needed by the international norms. Increase the sales capacity of your station The SCA-50 in its reduced version, can be installed as support to compressors already functioning at stations, increasing the capacity of the station with a minimal investment.
