Excalibur Slashes Airport Costs

Excalibur Slashes Airports Costs

Excalibur LPA has recently completed a major project to reduce the electrical consumption of air conditioning chillers at Manchester Airport by over 4,000,000 kwh.

Excalibur's involvement with Manchester Airport started with a pilot installation at the airport's Olympia House which was completed two years earlier. This was then monitored to determine the potential of Excalibur's technology to reduce power consumption.

With the results making a clear case for a larger scale project, Excalibur was given the green light to undertake the installation of Liquid Pressure Amplification and inverter control of condenser fans, as well as carrying out deep cleaning of condensers on 13 chillers located around the airport.

With several of the chillers operating on the ozone-depleting HCFC refrigerant R22, the use of which is to be banned from 2010, the airport also contracted Excalibur to compete a refrigerant change. All R22 was removed and replaced with ozone-friendly R422.

Excalibur has a long history of undertaking this kind of project, having completed similar work at Heathrow, Stanstead, Birmingham, Edinburgh and Glasgow airports. Excalibur staff are well used to the security implications of working'airside' but the recently introduced iris scanning system at Manchester made gaining access to the job site more like Mission Impossible than Terminal 3!

The project was completed with minimum downtime, avoiding the costly replacement of equipment and enabling the airport to remove ozone depleting refrigerants from site.

Manchester Airport is owned and managed by the Manchester Airports Group, a holding company owned by the ten metropolitan borough councils of Greater Manchester, and is the largest Britishowned airport group in the UK.

The airport has won numerous awards, including World's Best Airport 1995 and Travel Weekly Globe Awards' UK Best Airport

Before installation Excalibur monitored all three refrigeration systems to establish their condition

The work was carefully planned and shut-down periods were kept to a minimum.

Following the modifications, the system now operates more efficiently at much lower head pressure.

George Fletcher | Senior Project Manager | Norland Managed Services

I would like to take this opportunity to thank you and all others from within Excalibur involved with the development of this project, from my initial involvement through to today's handover meeting. All of which has run extremely well, with any issues uncovered being easily resolved with the proactive nature of you and your site team, which are a credit to Excalibur.

Hopefully, in the not to distant future I will have the opportunity to call upon Excalibur’s assistance and experience again on another LPA Project. Though in between times I would thank you again for your support and guidance.

Darren Crook | Operations Director | J O Sims Ltd

“Not only were the improvements in efficiency immediate and measurable, but previously it could take 48 hours to pull a chamber down to temperature, this can now be achieved in 12 hours, enabling us to respond to customer requirements very much quicker”.

"Excalibur installed LPA and inverter control to our Bitzer screw pack, the work was completed to a very high standard with minimum effect to production. Monitoring over the first 12 month period showed a reduction in power consumption of 38%. Several evaporators which had been starved of refrigerant now achieve temperatures where previously they struggled.
There have been no reliability issues and we are benefiting from a system which is not only energy efficient but also provides  improved refrigeration performance"

Dave Jeffs | Energy Matters

I have employed Excalibur to improve the energy efficiency of 8 Dunham Bush and Hitachi process chillers on two newspaper print sites, both systems showed a reduction in power consumption in excess of 35%. The installations were undertaken 6 years ago and have operated reliably since their commissioning. I would have no hesitation in working with Excalibur again.

 

Tony Bacchetta | Guoman Hotels

Excalibur have completed energy efficiency projects in many of our hotels, one of our major concerns is any disruption to the operation of the hotel and our customers.

The work was completed to a very high standard, and we were always kept informed of progress.

We are achieving the level of energy reduction projected with no adverse affect on the business and would have no hesitation in using Excalibur again.

Andy Watson | Energy Manager | BAA Heathrow Airport

"Following successful trials Excalibur have undertaken the installation of Liquid Pressure Amplification, inverter control of condenser fans and adiabatic condenser cooling to all of the large packaged chillers at Heathrow Airport, this project was completed successfully despite the difficulties of working airside.

As a result of the improvements in chiller efficiency, Excalibur have successfully completed similar projects at Stansted, Edinburgh and Glasgow Airports. "

Richard Shoulders | Operations Project Manager | British Telecom

"Excalibur have been undertaking energy efficiency projects for British Telecom for over 10 years, as a company they have always been professional and diligent. Their proactive approach has also identified several areas where we have been able to improve the integrity of our equipment."

Technical Manager | Avalon Leisure

"Excalibur completed energy efficiency projects at 3 of our Leisure Centres, the installation of boiler and inverter control (to pumps and fans) showed a very impressive reduction in both gas and electricity consumption on all 3 sites.

The opportunities were identified by Excalibur, who then completed the work to a very high standard, and have continued to provide support as required."

Services Facilities Manager | Manchester Airport

"Throughout the LPA project at Manchester Airport Excalibur provided a thorough and professional service ensuring the project was delivered on time with minimal operational disruption. The project delivered savings as quoted, the refrigerant change helped re-life ageing equipment and was seen as a great success, so much so that we are about to embark upon a second phase during 2010"

Chris Prentice | Project Management | UK NRG LTD

"Excalibur have installed Liquid Pressure Amplification and Inverters to 2 off 1300 kw data centre, process chillers. The cooling system is critical to this business, Excaliburs’ professional approach provided the customer with the confidence to undertake the project. Their condition monitoring also raised several maintenance issues, which we were able to resolve during the contract. Initial monitoring is demonstrating a 46% reduction in electrical consumption."
