Jaguar Land Rover turns to Gardner Denver for compressed air solution
When it came to selecting the compressed air system for its brand new Engine Manufacturing Centre (EMC) in Wolverhampton, Jaguar Land Rover selected supplier Gardner Denver to provide a solution capable of high energy efficiency, low cost of ownership and reduced environmental impact.
Based on the proven Quantima compressor installation at the Jaguar Land Rover Castle Bromwich assembly plant, Gardner Denver has engineered a larger system capable of providing up to 8,000 m3/h of high-quality, oil-free air to the new AJ200 machine shop and assembly halls.
The result is a highly-efficient compressor package with an intelligent control system, comprising three Quantima Q-52 centrifugal compressors and two DH110 RS machines, with variable-speed drives to match air output to plant demand.
Drawing on its existing experience of the CompAir Quantima compressors installed at its Castle Bromwich site, which have saved over 13,000 tonnes of CO2 per annum since their installation, Gardner Denver was selected to commission an energy-efficient solution for the site’s compressed air requirements.
Air quality is critical throughout the production process as the modern machine tools demand clean, dry and oil-free air. Any contamination could have an adverse effect on productivity and therefore, the compressors are optimised to provide completely oil-free air.
The Quantima compressor design avoids the need for a conventional gearbox, and therefore has no oil, no contact and no mechanical wear, meaning that there is no performance degradation over the life of the compressor. In addition, the two DH110RS machines are water-lubricated to ensure that there can be no oil in the compressed air network.
This oil-free air, which meets stringent ISO 8573.1 standards, is then transported to a refrigerant dryer and further energy-saving adsorption dryer before discharging in to the compressed air network.
An intelligent control system helps to minimise energy consumption by selecting the most efficient combination of compressors to meet plant demand for air. The larger Quantima Q-52 compressors act as the base load, with the smaller DH110RS machines coming on and off line to meet any peaks in production requirements.
Jaguar Land Rover will also benefit from the Quantima Q-Life predictive maintenance package with remote monitoring. This helps to prevent unscheduled downtime by tracking the compressors’ operating parameters and predicting when a service may be required.
To further enhance the energy performance of the installation, each Quantima compressor is fitted with heat recovery to reuse the otherwise wasted heat from the compression process, which is then used for space heating in the adjacent North plantroom.
The clean, dry and oil free air is then distributed through the machine shop and assembly hall network using lightweight aluminium pipework. Installed by Gardner Denver distributor, Shephard Engineering Services, the pipework is easy to maintain, corrosion resistant and with its smooth profile, provides low friction, helping to minimise pressure losses and therefore improving energy efficiency further.
