Cairo, Egypt
Compressed air and gas specialist CompAir will launch a new CNG compressor at NGV 2006 in Cairo, Egypt on 7th-9th November 2006. The Gazpack 42 water cooled compressor is a new addition to the popular Gazpack series of modular, ready-to-run CNG refuelling systems.
Designed primarily for medium sized public refuelling stations, the Gazpack 42 supplies between 275 and 555 m3/hr at a delivery pressure of 250 bar g. This model is suited for gas inlet pressures from 0.015 to 1 bar g. A higher inlet model, allowing inlet pressures of 2 to 7 bar g, is set for release early next year.
The Gazpack 42 incorporates proven CompAir compressor technology combined with advances in design and serviceability.
“Reliability is key to the successful uptake of CNG refuelling. The refuelling experience needs to be as easy as filling with petrol. At CompAir we believe a critical part of this is minimising downtime during routine servicing of the compressor, thereby reducing disruption to the refuelling process”, explains Abel Lord, Chief Development Engineer.
“We are continually looking for ways to reduce servicing times, for example, none of the Gazpack 42 parts require selective fitting, plus the third and fourth piston rings are supplied as a cartridge making replacement quick and easy. The coolers are all withdrawable and of straight tube design and that makes cleaning much quicker.
“Simple things have also been improved and now cleansing of the inlet filter doesn’t require interruption of the gas pipeline and oil top ups can be made without stopping the compressor,” continues Mr Lord.
“We are also aware of space restrictions and the absence of lifting gear at many installations, so the Gazpack 42 has no top end component weighing more than 25 kg. This eliminates the need for lifting gear during top end servicing. Additionally, all liners and pistons are easily removed and, to help with space restrictions, the majority of the service work can be carried out from one side of the compressor by a single service engineer, without the need for special tools or equipment.”
In addition to enhanced serviceability, the Gazpack 42 retains the key features that have made the Gazpack series so popular: reliability, a modular design offering flexibility and potential for growth, a well-balanced compressor design removing the need for special foundations, and a variety of packaging options; all helping to reduce site civil works and the cost of installation, maintenance and station expansion.
The Gazpack 42 is available as a minimum specification unit or packaged in an acoustic enclosure (72dB(A) at 1 meter), incorporating gas recovery, filtration and cooling systems. A wide range of ancillary station equipment is also on offer.
CompAir have now supplied over 950 CNG compressors to more than 25 countries and offers extensive turnkey project experience, advanced compressor design, and a truly local service capability. A “Total Solution” approach to CNG refuelling.
