Products Compressed air Range cooker manufacturer relies on genuine spare parts
To ensure maximum productivity, specialist in range cookers, AGA Rangemaster needs to ensure a dependable, quality source of compressed air is always available. With production running five days a week, its compressed air network must operate at peak performance at all times. Its original CompAir piston machines had been serviced
regularly with genuine spare parts providing reliable performance for over 20 years. Around 10 years ago, AGA Rangemaster decided to invest in variable-speed compressor technology to help improve energy efficiency. The company chose a new package from CompAir comprising two
L132 machines, an L75 variable-speed unit together with dryers, filters and an air/water separator. This station has now been operat- ing for over 10 years, and AGA Rangemaster believes this is thanks to programme of planned preventative maintenance backed by the provision of genuine spare parts. Vic Merulla, maintenance manager from AGA Rangemaster
explains: “Typically, non-genuine compressor spares and lubri- cants are cheaper to source than the manufacturer’s original parts. Clearly, all service and maintenance costs need to be factored in to our cost of ownership equations very carefully and, when finances are under pressure, it would be easy to choose cheaper alternatives. “However, by talking to the service and engineering team at CompAir, we soon learnt that fitting the wrong spare part can, in some cases, cause real damage to the compressor, ultimately meaning the machine can fail completely. This won’t just result in an expensive repair bill, but will affect our productivity too; so profitability would really suffer. “As a result, we have always used CompAir genuine parts, fitted
by a CompAir-trained service engineer to ensure that our compressors deliver the predictable performance we need.” Compair T: 01527 838200

Enter 309 Best of both worlds portable compressors
Doosan Portable Power’s Stage IIIB compliant 9/305 large portable compressor produces a free air delivery of 29.9 m3/min at an operating pressure of 8.6bar. Large portable compressors of
this type are used to provide com- pressed air for a wide range of drilling and boring machines for quarrying, mining, site investiga- tion, geothermal, mineral explo- ration and water well construction work. They also cover other specialist applications such as abrasive blasting, spray painting and standby and tempo- rary compressed air for industry. This family of large compres- sors offers the best of both worlds:
these compressors. Now compris- ing three models – the 7/26E+, 7/31E+ and 7/41+ – the Tough Top range of portable compres- sors combines durability with aesthetic design, making them an attractive investment
for
reduced size and footprint to min- imise transport costs and what is described as unparallelled service access to optimise maintenance work. In addition, features such as multiple air outlets, a bunded environmental base offering 110 per cent containment, central drains, forklift slots and tie-down points have been incorporated in
everyday applications in tough working conditions. As well as durability, the Tough Top canopy is also non-corrodible and can be supplied in customer colours. The modular design ensures
that a range of optional equipment can be added easily. Doosan Portable Power T: +32 (0)2371 6841

Compressor saves £30,000 a year in energy
In a quest for greater efficieny Northumberland-based Renolit asked Thorite to carry out an extended data-logging survey on its compres- sor system, which powered its complete manufacturing process. The results of the data-logging checked the performance of the
three existing fixed speed and one variable speed compressor, high- lighting that it was undersized for the job it was being asked to do. Overall energy consumption for all four compressors was 28,524Kw of electricity per week, at a cost of £2,139. Thorite proposed replac- ing the compressor with a new HPC CSDX165SFC variable speed compressor, plus a SAM 4/4 3D controller and visualisation package, capable of automatically adjusting compressed air output to suit varying power demands. The survey predicted the uprated compressor system would cut
electrical consumption by at least 400Kw per week, resulting in annual savings of over £15,000. In fact, now the new equipment has been fully installed by Thorite the results are even more dramatic. Energy consumption has fallen to 20,369Kw per week, at a cost of just £1559, with annual savings of over £30,000. Tony Husthwaite, the company’s energy, engineering support and

site services manager says: “The installation of the compressor and SAM controller has greatly improved system efficiency with impressive cost savings. The installation and commissioning by Thorite was to a very high standard, completed very quickly and with no disruption to the manufacturing process.”
Flanged filter
range extended The compressed air treatment specialists Hi-line Industries, has extended its product range with an extension of its HFF range of flanged filter units. These products can now be offered in seven sizes from DN80 up to DN300, covering air flow throughput rates from 1700 to 15,000 scfm. These filter housings have been designed solely with energy efficiency in mind, combining smooth, burr-free inner surfaces with in-line ports sized optimally to match required system flow rates. Incoming air entering the filter housings passes through a unique stainless steel head which transfers the compressed air flow through the filter elements, resulting in an exceptionally low differential pressure. The utilisation of in-line rather than
offset ports ensures a compact and simplified installation, while also providing easy access to the filter element chamber for service/replace- ments. A davit hinged bottom lid is also utilised on the filter housing so that filter element change out is a fast and ergonomic process easily and safely undertaken by only one person. Once the lid fixing nuts have been released, the bottom closure lid swings clear under its own weight, while still remaining securely attached to the filter housing. This bottom housing lid is also fitted with a central zero loss auto condensate drain as standard. Hi-Line Industries T: 01283 533377
