"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"

"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. "

"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."

"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"

"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."
