Products Compressed air Reducing compressor energy consumption the smart way
CompAir has strengthened its compressor controller range with the addition of the SmartAir Lite and a new visualisation package for the SmartAir Master. Designed to intelligently control up to four fixed speed compressors, the SmartAir Lite ensures the most efficient combination is selected for each applica- tion, avoiding the risk and costs of offload running and helping to reduce energy consumption by up to 30 per cent. Where compressors of the same capac-
ity are installed, the system has the ability to equalise running hours so that no machine is over or underused, resulting in longer maintenance intervals and lower overall maintenance costs.
The unit’s real time clock and timer con-
trol enables users to start and stop compressors at pre-set times allowing the system to reach its target pressure level prior to production, so users have com- pressed air availability at the start of a shift.
System set up and operating modules can be changed via the SmartAir Lite’s easy-to-use LED display. Some controllers require a high degree of technical input and detailed information about each compressor in the network to be installed correctly. In contrast, once each compressor is connected to the SmartAir Lite, the engineer needs to enter only minimal information as the controller will automatically identify all CompAir units in the system and will self-pro- gramme many stages. Non-CompAir compressors in the net- work can be easily connected to the SmartAir Lite via one simple i-PCB. CompAir has also enhanced its controller
Mobile unit measures residual oil content
Beko Technologies has launched its Mobile Metpoint measuring unit. Up until now the company’s Metpoint OCV has been used by customers required to have a regu- lar in-line monitoring of the resid- ual hydrocarbon vapour in their compressed air stream. However, following several inquiries about the possibility of measuring multi- ple points several times a year, Beko introduced Mobile Metpoint. The device has multiple mea- suring modes and will measure the following parameters includ- ing residual oil content (in the form of vapour); pressure dew- point; temperature; relative humidity in percentage; and
Finance scheme
for compressors A 0% finance scheme has been launched by Atlas Copco Compressors to fill a gap left by the recently with- drawn Carbon Trust 0% loans scheme and to encourage investment in energy efficient compressed air technology. The scheme will be available on equip- ment ordered from 1st July 2011. The initiative aims to help companies invest in the latest compressed air technology. Elwyn Smiles, regional sales manager northern Europe, Atlas Copco customer finance says: “The Carbon Trust 0% loan scheme was a boon for industry. We do not want to see that affordable funding disappear and so as part of our commitment to energy efficiency, the environment and the recovery of British industry, we are introducing our 0% finance offering for Atlas Copco equipment.” Atlas Copco T: 0800 181085

operating pressure in bar (g). The unit should be installed on systems behind oil free compres- sors or systems which include well maintained carbon filtration because the unit is so sensitive and will measure down to 0.003ppm of oil vapour in the line, well below ISO 8573-1 Class 1 for oil. The reason for taking the mea- surements are that the air enter- ing a compressor contains hydrocarbon vapours which will not be captured by a filtration system, only by a carbon filter or better a carbon tower. This is not to say that oil free compressors do not do what they are specified to do, merely that no one can con-
range with a visualisation package for the SmartAir Master, allowing users to monitor compressor systems remotely. The SmartAir Master will intelligently
control up to 12 compressors, fixed or variable speed, by operating all of the com- pressors in the network to the narrowest pressure band.
The visualisation package allows users to connect to the SmartAir Master via a dedicated web server which is given an IP address and can then be accessed by any- one with permission on the network using a standard internet browser, either at work, home or on the move. Compair

Membrane dryers set new standards
The new range of Hi-DRI com- pressed air membrane dryers from Hi-line Industries has been re- engineered and is said to achieve new standards in reliability, per- formance and energy efficiency. They feature a patented arrangement of structurally packed, permeable hollow fibres spirally wound on a support core. This creates an optimised design combining efficient air flow with high contact areas to maximise the drying performance within a compact unit size. These products are suitable for in-line installation to ensure the delivery of dry compressed air at the point of use.
As the humid compressed air passes through the Hi-DRI unit,
water vapour diffuses through the walls of the hollow mem- brane fibres without loss of com- pressed air. At the dryer outlet, a small volume of the now dry air is expanded and released into the annular space between the mem- brane fibres and the outer alu- minium shell. This air purge then sweeps away entrained water vapour to atmos- phere as a humid air stream. This technology helps eliminate conden- sation, oxidation and microbial growth, resulting in reliable and pre- dictable performance of down- stream air operated equipment.

out for dryers A well maintained, fully charged com- pressed air dryer is a vital component in ensuring the efficiency of any com- pressed air system’s operation - so it may surprise users to know that new environmental regulations mean many dryers are about to become redundant. If current model dryers break down, it may be impossible to repair them because over 40 per cent of dryers use HCFC R22 gas and under new F-Gas regulations only recycled product can be used – but it's rapidly running out. Worse still, recycled R22 will be banned from the end of 2014. Virgin R22 gas was banned last year, and since July this year all users with refrigeration dryers utilising 3kg or more of HCFCs must be inspected by a qualified engineer every 12 months. Thorite can provide full information on R22 gas redundancy. A member of its Capital Equipment Team can visit businesses and answer questions, as well as provide a quote for a replace- ment dryer and by-pass system. Thorite can also provide fully quali- fied engineers to check dryers and complete compressed air installations, to give total peace of mind that all F- Gas obligations are being met.
