    1. Company History

    The company BAUER KOMPRESSOREN was established by Hans Bauer inMunich in 1946 and produces compressors for the areas of breathing air,industrial air andgases for the delivery volume range of 6 Nm3 /h to 714Nm3 /h in the finalpressure range of 30 to 500 bar.

    Our users are customers from the areas of leisure sport, commercialbreathingprotection, industrial natural gas, air, nitrogen, helium and argon and from thefield of military engineering. Our company suppliesabount 9000 mediumand high pressure compressor systems every yearvia an international sales andservice network to customers in over 50countries. The BAUER KOMPRESSOREN enterprise provides jobsthroughout the world in 14 companies for approximately900 employees.

    Since the mid-70s BAUER KOMPRESSOREN is producing system solutionsfor the refuellingof natural gas-driven vehicles; these vehicles are assuming increasingimportance as a result of the constant rise in crude oil pricesand thecontinuing burden placed on the environment.

    To the present day the company has installed over 570 natural gas refuelling stationsthroughout Europe since the mid-90s; exact details andlocations can befound in our reference list. Particular mention should begiven to the factthat all system components of a CNG fuel station such ascompressor and storageunit, gas dryer systems, priority and sequential refuelling controls aswell as dispenser systems are developed and producedby BAUER KOMPRESSOREN and tuned up torun smoothly together.

    In addition, Bauer Compressors Inc. with registered office in Norfolk(VA)/USA,has so far produced over 400 natural gas refuelling stations forthe North Americanmarket.

    Utmost reliability and quality standards have enabled BAUERKOMPRESSOREN toassume a leading international position in all areas ofour product range. Thisposition is upheld by highly qualified personnelwith many years of experiencein all corporate areas and continues to befurther developed. It has not leastbeen achieved by the introduction ofa quality assurance system in accordancewith the high requirements ofISO 9001. This standard was accorded to thecompany by the Technischer berwachungsverein (TV PRODUCT SERVICE Munich already in1997.

    2. Decision-making Criteria in the Planning ofCNG Compressor Units

    Different aspects must be taken into consideration when planning naturalgasrefuelling stations:

    2.1. Daily Gas Requirement for Vehicle Refuelling

    When selecting the suitable size of compressor, the number of vehicles toberefuelled on a daily basis is decisive.

    During design it should be ensured that the compressor has a daily minimum runtimeof about 8-12 hours because, both from a technical andfrom a commercial pointof view, long idling periods should be avoided.

    When designing a compressor runtime of up to 12 hours per day an increase incapacity of 100 % can be realised without the necessity to installadditionalcomponents although the compressor system is well utilisedfrom the initial start up.

    If, due to a strong rise in refuelling demand, the required quantity of gascanno longer be delivered by the system, the modular design of the BAUERKOMPRESSOREN systemsusually permits an increase in capacity to berealised.

    For this purpose, depending on the necessity to extend the compressorand/orhigh pressure storage unit, an additional module is installed,thereby doublingthe gas delivery of the installed compressor system or thest
