More customers go for cleaner compressed
air
Zander purification units at the Nokia plant in Southwater and the Katies Foods' plant in Harrow are being used to ensure that compressed air generated is sufficiently clean
Compressed air is a major source of power in modern manufacturing and processing plants, but it is also expensive because generating it uses a great deal of energy Unfortunately, while oil-lubricated compressors are generally more economical to run than dry running compressors, more and more production processes and equipment demand "oil-free" compressed air

Using a Zander element on a 160kW compressed air installation could achieve annual savings of around £1500.
So, with the impending imposition of the Climate Change Levy, how can companies benefit from the economy of an oil-lubricated compressor whilst enjoying oil free compressed air? Using two recent installations, Nigel Morris managing director of Zander UK suggests an answer.
Zander, who specialise in the treatment of compressed air and gas, recently supplied two of their KMA and KEA compressed air purification units through Activ-Air Automation in Surrey, an authorised Zander distributor.
The units, which have now been installed at a Nokia plant in Southwater and a Katies Foods' plant in Harrow are used to remove dirt, moisture and oil to ensure that the compressed air generated is sufficiently clean for the customers' processing requirements.
Describing the installation in more detail, Dave Burton, technical sales director of Activ-Air says: "It is essential for both customers that the compressed air used in their manufacturing processes is oil-free.
If an unfortunate accident happens and all the oil from either compressor leaks into the line, the Zander units will shut down immediately and prevent any oil from entering their systems." This is achieved using a sensitive differential pressure gauge linked to a quick action shut off valve.
The air then passes through two pre-filters, which remove all condensed oil and water, leaving a clean but saturated gas to enter the dryer.
The desiccant dryer removes moisture down to a dew point of -40 øC.
This means the air is 'desert' dry.
After this process the air enters a bed of activated carbon, which removes oil to an almost undetectable 0.003 mg/m3.
Dave Burton sums up by saying that the Zander KMA/KEA purification units are simple but effective, which means Activ-Air can offer its customers an oil-free system without the expense of buying and running an oil-free compressor.
