Energy savings are out of this world for space technology company RF2M Technologies (RF2M), a manufacture of electronic components for the defence-aerospace sector, is saving more than £30,000 in energy costs per year after switching to a CompAir L75 variable-speed compressor with heat-recovery system from Gardner Denver distributor, Rodwell Bayne. The system has been so successful that the customer has recently invested in a second L75 RS compressor to achieve even greater energy savings. Overview ^ Client RF2M Technologies ^ Location Great Yarmouth, Norfolk, UK ^ Application High-efficiency instrument air ^ Products L75 variable speed compressor with heat recovery system ^ Customer Benefits £30,000 annual electricity savings / £3,000 per annum gas savings Application Details Part of the global API Technologies group, the site at Great Yarmouth has been manufacturing sensitive, high-tech electronics since the early 1980s. Operating 24 hours a day, seven days a week, RF2M has high-demand for a reliable source of instrument air which must also be highly efficient to ensure energy consumption remains as low as possible. In 2007, the customer invested in its first CompAir L75 variable speed compressor, which was one of the first in the industry to have a heat recovery system fitted. Recent analysis shows how significantly this investment has contributed to energy savings at the Great Yarmouth site, as Andrew Rodwell, director at Rodwell Bayne explains: "RF2M's manufacturing processes require high volumes of air and, over the years, its existing compressors had become

CASE STUDY Variable-speed technology - delivering electricity savings of over £30,000 per annum Heat-recovery system - reduces requirement on gas boiler by up to 66%, saving up to £3,000 per annum on gas costs Reduced off-load running - helping to improve energy-efficiency further Higher volumes f air - sufficient factory-air to supply nitrogen generation plant, removing the need for a separate compressor unit High reliability - to ensure 24/7 production is maintained costly to operate, due to inefficient loading. Following an air audit of the existing installation, including power cost calculations...
