Newest screw air compressor halves energy costs

screw air compressor The Boge SLF series combines a direct-coupled drive system with frequency control to provide the

ultimate compressor for pressure control under variable output requirements. LH Plastics enjoyed compressed air energy cost

savings of 67% per annum after installing a Boge SLF40 frequency-controlled screw compressor This low-carbon technology was

financed with an interest-free 'energy-efficiency' loan from The Carbon Trust Compressed air is used for a number of

processes within the factory as part of the injection moulding machines, pad printing and hot foiling processes to powering

the robotic and manual paint spraying systems. As part of a company-wide environmental drive, Paul Cahill the Production

Director at LH Plastics contacted Boge Compressors to review the energy efficiency of the current compressed air system. The

existing compressor had provided several years of reliable service but a comprehensive compressed air energy audit revealed

that changes in compressed air demand coupled with the age of the compressor, meant the system was not performing

efficiently. Boge recommended replacing the existing compressor with an SLF 40 to optimise energy efficiency and performance.

The Boge SLF series combines a direct-coupled drive system with frequency control to provide the ultimate compressor for

pressure control under variable output requirements. The SLF is therefore a low-carbon technology that works strictly in

accordance with the compressed air demand by producing the exact volume of compressed air at the pressure required. Frequency

control minimises idling time and evens out air demand fluctuations. A Boge SLF40 was subsequently installed at LH Plastics.

LH Plastics chose to purchase the new energy efficient equipment with an interest free 'energy-efficiency' loan from The

Carbon Trust. These loans are aimed at SME's within the UK who are making a commitment to save energy by investing in energy

efficient technologies to replace dated existing equipment. Paul Cahill said "We have been very satisfied with the

performance of the Boge SLF 40 to date - not least because we have created a 67% cut in our compressed air energy costs per

annum".
