Airchannel Announces Energy Efficient L90 Compressor

16 Jun 2008

There’s great news, as CompAir launches its completely redesigned L90 kW to 132 kW oil-injected screw compressors, which deliver high-end range of machines that addresses operators’ key concerns for reduced cost of ownership.  

Commenting on the new CompAir range that is available from Airchannel, Alastair Shanks, Managing Director said “This range of compressors is better in every way - including a new compact footprint, reengineered components, increased air output and reduced parts’ and maintenance requirements.”  

There are four models in the new range; L90, L110, L132 and L132 SR variable speed unit, that deliver capacities from 17.45 to 22.87 m3/min and pressures of 7.5, 10 and 13 bar.  

With rising energy costs being a major concern for customers across the globe, its essential to consider the compressors lifecycle costs. The new range incorporates specific features and components that will improve energy usage, reduce maintenance downtime and parts’ costs and deliver better overall performance. The result is a range of gear driven machines that deliver up to 15 % more air output with a lower CO2burden improving the compressors’ environmental credentials too. 

The new range of compressors provides a minimum 15 % increase in air volume flow with greater energy efficiency than the previous models and also uses CompAir’s new gear drive, which increases reliability and efficiency even further.  

Airchannel customers can gain maximum energy efficiency improvements with the L132 SR variable speed machine, which can reduce running costs by 25% on average. This compressor uses an innovative Switched Reluctance (SR) drive that varies the speed of the compressor according to air demand and could give a minimum saving of at least €15,000 running at 4000 hours a year, based on average energy costs.  

The combination of innovative component design, a 20% reduction in parts and excellent  accessibility to all areas of the machines makes the new range of compressors easier to  service and more cost-effective to operate.  

The Alpha Air End EK230 has an integrated oil filter and thermostatic valve, limiting the number of tubes and hoses that would otherwise require routine replacement. Higher reliability is also achieved with fewer points of leakage and the unit design means that there is greater space for  cooling air to circulate, to prolong its life.  

All major components are arranged to enable maintenance engineers easy access for routine  servicing, helping to reduce equipment downtime. Specific attention has been paid to the oil  separator, which includes a hinged cover and also an easy-view oil-level indicator.   

At just 3.2 m2, the new compressors have an exceptionally small footprint, meaning they can  take up to one third less floorspace than comparable models, making them ideal for  installations where space is at a premium. The low speed air-end, radial fan and a noise  damper at the cooling air inlet also ensure that the machines run quietly, with low noise levels  starting from 73 dB (A) on the L90 model.
