SOLUTIONS 02 PROVIDING RELIABLE COMPRESSION SOLUTIONS SINCE 1898 The Gazpack range of CNG compressors is manufactured primarily at the state-of-the-art CompAir facility in Ipswich, England. The company moved from the original Reavell factory, established in 1898, to Reavell House in 2005 and enjoys enhanced manufacturing, test and paint facilities, as well as environmentally friendly water and oil recycling systems. Shanghai CompAir-Dalong HP Equipment Co. Ltd, a Joint Venture established in China in 2004, also designs and manufactures European quality CNG stations for the Chinese and Asian markets. CompAir is registered to ISO 9001-2000 Quality Management System by Lloyds Register Quality Assurance and conforms to the requirements of the European Pressure Equipment Directive (Module H) where appropriate. Witness testing and certification by most major accreditation bodies, such as Lloyds Register and TUV, can be met on request. As a manufacturer of CNG systems, CompAir retains greater control over quality and technological improvements in the compressor package, and a dedicated team of highly experienced project and design engineers is able to customise the Gazpack range to meet specific customer needs. Combined with specialist partners who are carefully selected to provide quality ancillary equipment such as dispensers and dryers, CompAir is able to provide a complete and reliable solution to meet the customer's refuelling needs.

0 SOLUTIONS Turnkey Solutions With over 25 years experience in the CNG industry CompAir has extensive experience providing project management assistance for turnkey projects. PROVIDING TURNKEY PROJECT MANAGEMENT FOR OVER 25 YEARS CompAir offers the expertise to develop a complete refuelling station, covering: Project feasibility Site suitability Planning and approvals process Station and equipment design Utility procurement Equipment manufacture Site preparation Installation Commissioning Training Station Design Station design is a critical part of any refuelling station project. The CompAir team of experienced sales managers and engineers can advise on all aspects of station design, taking into account the station type, fleet type and purpose, fill volume, site limitations, budget and other issues. Fast Fill Fast Fill stations primarily utilise gas drawn from a storage bank previously filled by the compressor, rather than direct from the compressor. The speed of fill is comparable to petrol or diesel and is typically found on public forecourts. This method is always used where the exact volume of gas in each vehicle must be quantified.

STATION DESIGN 04 Time Fill With time fill posts the vehicle is refuelled directly from the compressor without the need for storage cylinders. Refuelling is therefore slower and more suited for vehicles left overnight at a depot, such as buses. With time fill posts the quantity of fuel dispensed into each vehicle is not easily monitored and therefore time fill is unsuitable for public refuelling stations. Mother & Daughter The mother-daughter concept is a 'virtual pipeline' where natural gas is drawn and compressed from the pipeline at the Mother site and transported to the Daughter site by truck and trailer. This is usually used to service sites that are not located near a natural gas pipeline. Once at the daughter station vehicles can be filled directly from the trailer using a CNG dispenser. The mobile cylinders are filled to above 200 bar at the mother station but due to pressure drops during decanting, it is essential to have a compressor on site to ensure pressure in the delivery line remains above 200 bar. When the pressure in the trailer cylinders finally drops below 20 bar, the trailer is returned to the mother station for refilling. A daughter station will usually have several trucks and trailers working on a shuttle system. THE MOTHER-DAUGHTER CONCEPT IS IDEAL FOR SITES NOT ON A PIPELINE

11 ANCILLARIES Ancillaries CompAir offers all the ancillaries required for a fully operational refuelling station: Storage Priority Panel Dispensers - fast fill and time fill options Controls Dryers Electronic access Remote access Gas detectors Dew point monitors Cascade storage systems A Fast Fill refuelling system provides gas on demand using a combination of the compressor and prepressurised storage to maximise a 200 bar fill for the vehicle. There are three key elements: Priority Panel, Cascade Storage (typically banks - High, Medium and Low) and Electronic Dispenser. The Priority Panel prioritises the use of gas from the compressor to the Cascade Storage: firstly to the High Bank, then the Medium Bank and finally the Low Bank. The Electronic Dispenser draws on gas from the storage in reverse order (Low, Medium, High) and finally directly from the compressor if demand has exceeded the storage capacity. This system maximises vehicle fill and station capacity and is recommended for public stations. Storage CompAir offer a variety of storage systems designed specifically to local standards. All vessels and cylinders can be designed to meet ASME, DOT and TPED specifications and are fully weatherproof removing the need for enclosures, although enclosures are available on request. STORAGE TYPICAL SPECIFICATIONS 80 litres water capacity per cylinder Compressor feed lines 12mm OD 16 stainless steel tubing & fittings Dispenser bypass line 16mm OD 16 stainless steel tubing & fittings Mechanical valves set storage bank filling priority Maximum working pressure 50 bar g Gauges fitted to compressor feed line and all storage bank lines Lightweight panel with flexible mounting options

ANCILLARIES 12 Dispensers A full range of electronic and manual dispensers are available, with simple manual operation or fully automatic dispensing with card access technology. TIME FILL POSTS Includes fuelling valve, pressure gauge, hose and connector assembly Cost effective with high reliability Unmanned operation once connected Can lower energy costs through use of cheaper off peak energy rates No need for storage systems Ideal for depot based overnight refuelling with modest daily mileage Dryers Natural gas vehicles require high quality clean gas to ensure long life and minimum maintenance. CompAir offer a range of dryer systems to ensure full protection for the vehicle and the refuelling station. Options include both Low Inlet dryers (precompression) and High Inlet dryers (post-compression). High Inlet dryers are available as static or re-generative systems. The choice of dryer is affected by dew point, inlet pressure and compressor flow rate. MANUAL FAST FILL DISPENSERS Single or dual hose designs with Breakaway safety connections NGV1 or NGV2 nozzles available 1 bank sequencing options Ideally suited for single car dispensing or as a backup dispenser at a refuelling depot ELECTRONIC FAST FILL DISPENSERS Flow rates up to 80kg/min Single or dual hose designs with Breakaway safety connections NGV1 or NGV2 nozzles available Coriolis mass flow meter Explosion proof and intrinsically safe electronics 1 bank sequencing options Suitable for electronic card access and payment systems and stations with high speed filling requirements Controls CompAir is able to provide a full range of control systems from simple manual controls to complete systems, with optional PLC, designed for unmanned operation. Control systems can be mounted remotely or within the canopy and are designed around local and national standards ensuring full compliance with regulations. CompAir can also offer remote monitoring capabilities. This provides useful data from the installation which can help to devise more efficient ways of working, including energy conservation, early fault diagnostics and shutdown planning.
