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 thestored gas quantityimmediately available from the high pressure storageto satisfy refuellingpeaks.

Irrespective of whether a compressor and storage unit is selected from theMFS,CFS or CTA series, the modular setup of the system provides a commerciallyfavourable solution for every use constellation designed to caterto theexpanding CNG market.

2.2. Gas pressure in the Gas Grid

Another important aspect is the use of gas pressures in the gas networks.

As a result of the direct, non-regulated use of the actual gas pressurethespecific power consumption of the compressor and therefore the operating costsof the compressor system can be reduced because less energyis required tocompress the already pre-compressed natural gas.

When working with elevated gas pressures, the actual runtime of the compressor to beexpected on a daily basis should be taken into considerationbecause a higherdelivery performance of the compressor will result whenusing booster systemsdue to the higher gas pressure of the gas grid.

If a booster is used for a daily runtime of only a few hours, a gas intakepressurereduction may well be advisable for financial reasons.

It may also be a good idea to adjust the initial gas pressure to themaximumadmissible compressor gas intake pressure if high connectioncosts to a highpressure supply network with low gas demand potential areto be expected. Adirect unregulated gas pressure use of approximately1000 Sm3/day and more is tobe considered as required gas demand forvehicle refuelling.

2.3. Depot or Public Refuelling

Another aspect to be considered is the nature of refuelling in terms of thecustomers application.

In the case of a depot refuelling station, mainly company-owned vehiclesare refuelled, whereby a restricted semi-supply to third parties is also possible. In these casesa calibrated filling point with automatic card readersystems can be selectedbecause these stations are usually operatedwithout fuelling staff.

If the station is to be integrated in a public branded refuelling station, suchasESSO or similar, a dispenser must be used that can similarly be obtainedfromBAUER KOMPRESSOREN which can be connected with a large varietyof cash tillsystems via popular interface protocols.

4. Technical Description

4.1. Outdoor Natural Gas Compressor Systems

4.1.1. Mini refuelling station Compact (MFS Compact)

The introduction of the Mini refuelling station by BAUER KOMPRESSORENhas been verywell received by customers. Since its market launch in 1997more than 140 unitshad gone into operation by the year 2008.

The MFS Compact series is a very reasonably priced starter model for CNGvehiclerefuelling; with reasonably priced acquisition and maintenancecosts as well as compactdimensions, it is reliable and maintenance-friendly.

In keeping with market demands and as part of its ongoing product maintenanceand improvement, BAUER KOMPRESSOREN reviewed theconcept of the MFS Compact series in2008, developed a new PLC controlsystem and integrated the compressor systeminto a compact concretebuilding.

This system was specially designed by BAUER KOMPRESSOREN for the refuelling ofmaterial-handling vehicles (forklift trucks) or in-house fleetvehicles. It can,of course, also be used as fuelling system for natural gasvehicles in publiclyaccessible refuelling stations.

Due to the inclusion of a highpressure storage unit with up to 30 high pressure storage cylinders each with 80 litresgeometric volume in the concretebuilding means that a largequantity of compressed natural gas is availablefor fast fill refuelling even atlow compressor performance, enabling therefuelling time to be reduced to aminimum compared to a traditional slowfill refuelling station.

The MFS Compact series can be customized depending on the applicationandrequirements with a 3-bank storage rack or with a 1-bank storage racksystem, e.g. for refuelling forklift trucks as the most cost-favourable solution.

As additional accessories both simple filling systems without mass flowmetering as well as the complete CNG dispenser programme with flow meters (Coriolis)are available to suit the application requirements.

4.1.2. Compact refuelling station - DUO, Small (CFS-DUO)

The basic version of the CFS-DUO series is intended for initial operationwithone compressor and one storage system. If the amount of compressed natural gasto be provided daily to refuel vehicles exceeds themaximum capacity of thecompressor, the CFS-DUO series can be extended by a second compressor and, in the event ofthe peak load refuellingincreasing, by a second storage rack tank (integrated in an extension building) without any problem.

The CFS-DUO series, small is available with compressor modelsC15.2-13, C22.0-30 and CBK15.4-13 (see also Table 2).

By minimizing the ex-protection zones to be considered, the entire CFS-DUO seriesis ideally suited for situations where space is at a premium, suchas publicinner-city refuelling stations. Just like all BAUER KOMPRESSORENnatural gas refuelling systems,the CFS-DUO series features fully automated operation (basic/peak load operation, redundancy, supply of up to4 filling lines operated at the same time).

4.1.3. Compact refuelling station DUO, Large (CFS-DUO)

Other than the small CFS-DUO series, this series was designed forcompressors with high capacities and/or larger gas intake pressure ranges.Thecompressors available in this series are equipped with gas/water heatexchangersfor intermediate and after-cooling. The heat transfer to theenvironment takesplace through a water/air recooler set installed on thebuilding roof.

In particular this model of cooling enables a sound emission level under 60dB(A)to be achieved even for larger compressor systems without additional soundinsulation measures.

Otherwise, the structure of the system and the extension possibilities fortheinstallation of a second compressor and/or second storage unit are thesame asfor CFS-DUO series, small.

The CFS-DUO series, large is available with the compressor modelsshown in Tables3.x.

4.1.4. Gas Drying

As a standard, all natural gas compressor systems from BAUERKOMPRESSOREN are equipped with a gas dryer on the high pressure sideincluding an (optional) electronicpressure dew point monitoring. Oncethe drying agent used has achieved saturation point the compressor unitisautomatically shut off and a message is displayed on the PLC controller.Thisreliably rules out the possibility of condensate moisture reaching the3-bank storage rack and the downstream refuelling technology. It alsoguarantees fault freeoperation of the system even with the lowest ambient temperatures in winter.

Furthermore, the TV, i.e. (Notified body CE0036) as the technical safetyauthority in Germany for inspection of pressurized equipment, extends theinspection interval for the first reinspection from 5 to 10 years starting fromthe commissioning ofthe system, representing an economic advantage inthe operating costs to beborne by the customers.

4.2. Indoor Natural Gas Compressor Systems

4.2.1. CTA Series

The natural gas compressors of the CTA series are housed in a noise-insulatingsheet metal enclosure. However, these systems are solely designedfor indoor use.

Basically these compressor systems contain the same compressor modelsas the CFSseries, including booster systems. Of course, all the storage andrefuellingsystems in the delivery range can be combined with the compressor models of theCTA series.

It must be ensured that the electrical control system is installed in anon-ex,gas-tight room separated from the compressor system.

The CTA series is available with the following compressor models:

- C 120-5.5; C 15.2-13; C 23.0-38; C 23.2-38; C 24.0-75; C 28.0-75/90;C26.0-110, C26.2-110

4.4.1. Storage Systems

In most applications so-called 3-bank storage batteries are used asintermediate storage for fast fill refuelling stations and consist of three individualpartial storage banks: the high, mid and low bank.

These banks contain a different number of pressurized cylinders which,however, areassembled together in one rack. As a result of this division,unlike an arrangement of the cylinders in row, (1-bank system) a higher degree of exploitation and thus a larger available gasquantity can beattained for directly successive vehicle refuelling.

Due to the difference between storage pressure (300 bar), in the3-bankstorage system and the empty vehicle tank, the gas flows into thevehicle tankduring refuelling as a result of the drop in pressure. The maximum permissiblevehicle filling pressure is 200 bar related to an ambienttemperature of 15 C. Different storage racks are available depending on the customer-specificrequirements. If necessary, these can, of course, be designed as 2 or1-bankstorage systems.

The size of the storage battery is determined as dependent on the numberofvehicles to be filled directly in succession in peak load operation.

A gas volume of approx 36 m3 is derived for a vehicle with 160 litres geometrictank capacity.Compared to the free gas quantity available from the3-bank storage system, thenumber of vehicles to be filled directly in succession can be determined easily by the size of the tank of the 3-bank storage system from thevehicles to be filled, and vice versa.

Example: B2400

Gas volume available (300 bar): approx. 277 m3 Number of possible peak refuellings at a CNG demand of 36 m3 each indirect succession: n = 277 m3 : 36 m3 8

Depending on the installation model and location, a selection can bemadebetween enclosure in a weatherproof sheet metal enclosore or an openversionfor installation in an existing building. Additionally extended storage tankswith concrete enclosure are also available for ex-protectionzones, inparticular for the inner-city area.

4.4.2. Priority and Sequential Control Units

The priority control panel controls the priority filling priority of the3-bank storage system usually used. The compressed natural gas (CNG)flow comingfrom the compressor and gas treatment system is led into thehigh bank at first. Ifthis achieves the maximum set pressure value the priority control panel then guidesthe gas flow into the mid bank and finallyto the low bank.

During the vehicle refuelling the sequential control panel usesthe compressed gas in reverse order, always starting from the low bank first. Ifthegas pressure therein is no longer sufficient to refuel the vehicle to 200bar(15 C), there is a changeover to the mid bank using special valve mimics. Theresidual quantity is taken from here to refuel the vehicle completely.

The high bank is still available for high peak fuelling frequency if themiddlebank also fails to attain the necessary filling pressure of 200bar(15C). BAUER KOMPRESSOREN offers the systems shown below which can beused for 250bar and for 300 bar. The difference in these two modules isthat the VR 300 AC is additionallyequipped with a pressure reducer anda filling pressure safety valve in order tomaintain and limit a maximum of250 bar for ambient temperature-compensatedfilling pressure to the vehicle. Both systems are supplied with low pressure controlair generatedby an aux. compressor system in the electricity room.

Both models can be extended for the operation of natural gas dispenserswith 2 mass flow meter systems each.

The VR250 AC is predominantly The VR300 AC is used for reused for the refuelling of large quantities as for trucks and passenger vehicles buses ina shortest refuelling time.

4.5. Filling Equipment

4.5.1. Fill posts

Which dispensing equipment is used determines whether a fill post or adispenser is used.

The fill post series FP is frequently used in natural gas refuelling stationsindepots, especially when refuelling stations are not continuouslymanned. Using acard reader system to release the fill post means thatvehicles can be refuelled bythe drivers themselves. Invoicing will then bemade via arefuelling data processing program to the customer.

BAUER KOMPRESSOREN has several models on offer depending on whichversion isrequired:

- fill posts without mass flow meter (car, bus)

- fill posts with mass flow meters (car, bus), gaugeable inconnection withan automatic vending machine.

4.5.2. Dispensers

The use of a dispenser (in contrast to a fill post without massflow metersystem is absolutely imperative for operating a public refuelling station forstatutorycalibration reasons. The display shows the unit price, quantityrefilled as well as the final pricesimultaneously.

The dispensers are available according to customer requirements with oneor two hoses,with one or two mass flow meters for non-simultaneous orsimultaneous vehiclerefuelling on both sides of the dispenser. The positioning of the hosecolumns and the display system can also be freely selected depending on thevehicle approach side.

The dispensers of the ZSxx-DWx series can be used both for the refuelling ofcars and buses and are available in the suitable colour and corresponding logoof the refuelling station (ESSO or similar). Usually the dispenser computers are directly connected to the cash tillsystem in the refuelling station shop so that the familiar refuelling procedure is thesameas for liquid fuels. As required, the dispenser can also be operated inconnection with an automatic vending machine (EC, VISA etc.).

Safety accessories such as break-away systems in case of an accident,which ensure agas-tight separation of the connection lines from compressor to dispenser inthe event of danger are also optionally available atcustomer request.

5. Planning your Natural Gas refuelling station

5.1. Slow-Fill / Fast-Fill

5.1.1. Slow-Fill

When designing a CNG refuelling station the question of the suitable fillingmodeshould be clarified first of all.

If it is possible to refuel all vehicles of a fleet over a long period oftime, theprocurement of a slow-fill system may come into question. This willusuallybe a smaller vehicle fleet (5 - 7 vehicles) which are refuelled at adepot refuelling station during the available breaks or at large refuelling stationsfor thefuelling of bus fleets with more than 20 buses.

In the case of slow-fill refuelling the compressor pumps the compressednatural gas to the vehicle tank directly without intermediate storage.

The vehicle can be refuelled with the supplied quantity of CNG from thecompressor stationduring the corresponding time via a filling nozzle.

5.1.2. Fast-Fill

If, however, it is intended to sell to a third party or refuel a larger numberofvehicles, the fast-fill system should be selected.

For this purpose the compressed gas is firstly stored in a 3-bank storagebattery beforeit is refuelled into the vehicle tank via the natural gas dispenser. Fill timesof between 1 and 2 minutes (80 liter tank) can usuallybe realized in this way.

However, the maximum available gas quantity in this 3 bank store must bebornein mind when filling vehicles as described in the "storage systems"chapter.

6. Project Planning

6.1. Design, Installation, Foundation Plan

When planning and setting up CNG systems, BAUER KOMPRESSOREN isyour competentpartner. We plan and realise the CNG refuelling stationin co-operation with the client from design through to turnkey delivery (excluding any requisite buildingpermits).

When designing a CNG station the important parameters are the numberof vehiclesto be refuelled, the size of the vehicle tank and the refuellingpeaks. Inaccordance with the customer's specifications, we will bepleased to draw up anoptimized design and concept of the natural gasrefuelling station (filling profiles,extendibility, feasibility study etc.).

Together with the customer the installation of the CNG refuelling stationis drawn upfocusing on safety and cost. The ex-protection zones, customer friendlypositioning of the dispenser, noise emission of the compressor system as wellas an optimised high pressure pipe layout betweencompressor storage unit anddispenser are important parameters.

After determining the placement of the system, our team of engineers willdrawup an installation and foundation plan that in particular specifiestheinterfaces for the operation of the system in detail such as the buildingdimensions, gas input piping, electric power supply, pneumatic andelectrical connectionlines to the dispensers and station shop.

7. Installation to Turnkey Delivery

7.1. Placement

In consultation with the client, the best location for the CNG fuelstationwill be selected by our engineers.

After the client has done the concrete foundation, we can erect the entireCNG station, provide all of the electrical cabling and piping.An additional important aspect is to meet statutoryex-protection regulations.

Due to the minimized explosion protection zones of our MFS and CFS natural gasrefuelling stations we are able to find an optimum installationsolution even if spaceis limited.

The connection to anexistingcash till system is provided on request by BAUER KOMPRESSORENin co-ordinationwith the outside companies involved.

7.4. Commissioning

After successful installation the compressor system is started, checkedagainand some test refuellings are performed on natural gas drivenvehicles or possibly withour own test equipment.

BAUER KOMPRESSOREN provides the project organisation and schedulingalso for theinstallation and commissioning of the compressor storage unitincluding the dispensertechnology so that commissioning of the CNG refuelling station will generally only take afew days.

7.5. Final Safety Inspection by TV (Notified Body)

In our factory in Munich the components such as compressor, storage system andother equipment of the delivery package can be subjected to partial acceptanceinspection by the TV (Notified Body: CE 0036).

After successful erection at site,the installation is checked by a TV expertor another safety inspection authority including the technical documentation ofthe technical partial acceptance inspection in the manufacturer'sfactorysubjected to a standard inspection.

This acceptance at site is also carried out by our serviceteam together withthe relevant safety inspection authority.
