04/2008 - Precision moulder slashes energy costs

LH Plastics, a precision moulder and printer of engineering thermoplastics, has enjoyed compressed air energy cost savings of 67% per annum after installing a BOGE SLF 40 frequency controlled screw compressor. This low carbon technology was financed with an interest free 'energy-efficiency' Loan from The Carbon Trust.

LH Plastics, based in Bradford West Yorkshire, produces a diverse product range for the electrical engineering and domestic markets in a wide variety of thermoplastics.
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 long standing compressed air partner 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 to its optimum in terms of energy efficiency.

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 SLF 40 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!"
