How do I apply the most innovative solutions, products and services to my live environment?
In answer to the above question Airedale will demonstrate how you can maximise the efficiency of your live environment without compromising resilience.
With over 40 years’ experience in IT cooling design, build and retrofit across systems, services and controls integration, Airedale is uniquely positioned to present this seminar. The presentation will include a case study on BAE Systems where a year-long retrofit programme has achieved annual savings of 70-80% on computer room air conditioning energy costs, equivalent to £350,000, with a payback of under 15 months.
Speakers: Stuart Kay, Business Development Director & Adrian Trevelyan, Aftersales Manager

“”
Airedale was selected as the most
competent company with the best
product to meet our needs.
The project involved retrofitting new EC fans,
chilled water valves and controls to over
70 CRAC units over a 12-month period.
The savings have been measured and amortised
to give an annual saving of around £350,000
