COMPRESSED AIR
BCAS LAUNCHES ESSENTIAL INDUSTRY GUIDE TO COMPRESSED AIR INSTALLATION
he British Compressed Air Society (BCAS) has launched a new compressed air installation best practice guide (BPG 101-6). As one of the only truly impartial guides in the UK, the guide covers ‘installation’ in terms of the collection of equipment and processes within the compressed air system.

Compressed air accounts for a considerable amount of electricity consumed by industry and compressed air systems are used extensively in virtually all industrial applications. The guide therefore provides essential information that can help readers reduce their energy consumption and ensure maximum uptime, while meeting legislative requirements to ensure health and safety is prioritised. Providing step-by-step information for the correct specification, installation and maintenance of compressed air equipment as well as its end-of-life removal, the 272-page guide is essential reading for compressed air industry employees, plant engineers, maintenance technicians and end users.
The reliability of compressed air systems is a major consideration for operators, as any issues with supply can result in potential downtime. In addition, selecting the right equipment can be a complex task. It can affect everything from maintenance schedules and costs to ongoing air purity (quality), as well as the
annual electrical energy cost of air production, which can be several times the cost of the original equipment.
The best practice guide is divided into a series of easy-to-read chapters to make specification as straightforward as possible. These cover compressed air system assessment, equipment selection and system design, including pipework. Detailed information is also provided around installation, commissioning, maintenance, system management, and finally, legislation and standards. Vanda Jones, BCAS Executive Director added:
“Our new best practice installation guide has been developed by experts in our industry to provide a complete and comprehensive suite of information for our sector and its compressed air users. Each chapter had its own dedicated working group made up of BCAS members and experts in the industry from both the manufacturer and distribution sectors, led by Tim Preece, BCAS’s Technical Officer to ensure the best information and product neutrality. The resulting guide is a fantastic, impartial resource for the sector.
“The components of a compressed air system must be selected and maintained with care. In many cases the system is a major consumer of energy and any decrease in efficiency will adversely affect the overall operating cost of the plant.
“Therefore, the correct choices when made early in the specification stage alongside the correct maintenance procedures, will have beneficial whole life cost and energy saving implications.
“We would like to extend our thanks to everyone who contributed to this guide, to make it the ideal companion for any users looking to improve the efficiency of their compressed air system.”
Companies can purchase the guide either as a PDF download or a hard- wearing, bound copy for £14.95 (plus VAT and postage) directly from the BCAS website. For any other queries about the guide please contact the BCAS team at

HPC’S WHITE PAPER OFFERS GUIDANCE ON FIXED VS VARIABLE SPEED DRIVE SCREW COMPRESSORS
W
hile some compressed air providers will advocate the use of Variable Speed Drive (VSD) screw compressors in all applications, a new White Paper authored by HPC challenges this assumption. In its White Paper, titled ‘Fixed Speed Drive vs Variable Speed Drive Screw Compressors’, HPC explains that VSD screw compressors are not the one-size-fits-all compressed air solution that VSD proponents would have customers believe. “It is vital to analyse your own compressed air demands to determine whether a Fixed Speed Screw Compressor, VSD Screw Compressor, or a combination of the two is right for your application,” says Mathew Gould, National Distributor Manager at HPC Compressed Air Systems. “In many cases, VSD Compressors may not be the most efficient or cost-effective choice.
“HPC understands that selecting the right compressor(s) for a facility’s compressed air demands is crucial. That’s why we have created a free White Paper on the difference between Fixed Speed Screw Compressors and VSD Screw Compressors.” HPC’s White Paper covers some of the most important considerations when choosing the right compressor for your needs, including: · The differences between Fixed Speed and VSD Rotary Screw Compressors · How Fixed Speed & VSD Screw Compressors work · Which type of Screw Compressor is the most efficient (and under what conditions) · VSD Harmonics · Motor energy losses · Specific Power variances · Energy savings

· The value in Compressed Air Energy Audits “The key to a compressor’s efficiency is its Specific Power”, continues Gould. “This means the compressor’s complete package and compressed air system needs to be considered to ensure the most efficient solution.”
To ensure this, the White Paper recommends an Air Demand Analysis (ADA) is completed to determine the customers individual air requirements. “This enables customers to identify the most economical and efficient configuration, whether that is a single or multiple Fixed Speed solution, a VSD solution, or a combination of the two,” concludes HPC’s Gould.
