Edenaire helps Belgacom reduced CO2 emissions with energy efficient cooling solution
As part of its drive to develop sustainable environments for customers, Edenaire has helped Belgacom to cut its costs dramatically by reducing the telecommunications providers’ carbon footprint, with a purpose-built energy efficient solution for cooling its telephone exchanges.
Close control air handling units were used in all Belgacom’s exchanges, but the effects of climate change encouraged a review. Savings achieved by other European telecoms provided an additional incentive.
Edenaire attended a series of meetings in Liege, resulting in a theoretical design delivering lower running costs, maintenance and 24/7 reliability. This resulted in a solution using Edenaire’s e-BTX, BTA and IPAC units.
A pilot site involving 11 e-BTX units, two BTX units and two IPAC units, based on a net cooling capacity of 338kW reduced yearly CO2 production by 380 tons and produced yearly savings of €50,527.
“By keeping the amount of power to run the cooling system to an absolute minimum by using fresh filtered outside air whenever possible; EC fan motor technology which generates up to 50% energy savings over standard curve forward curve DC fans and “ECO” cooling technology which reduces the fresh air supply duty by 20%, the e-BTX provides reliable energy efficient cooling.” says Rob Jones, Telecoms Cooling Manager.
The pilot was part of Belgacom’s Sustainable Development strategy. It shows that by improving business practices and adopting a greener approach companies can contribute to a more sustainable environment and save substantial sums of money.
“Belgacom has shown that addressing energy issues can be good for the environment and good for business,” says Rob.
Belgacom is now changing its policy to fresh air free cooling with DX wherever possible in its network development.
The eBTX range comprises four models; 15, 22 & 30kW eBTX UF and 30kW eBTX DF and incorporates the latest advances in fans, controllers, software and mechanical components. The result is a robustly designed range of fully featured air handlers fully compliant with ETSI (European Telecommunications Standard Institute), European Norm (EN) 300 019 Class 3.1.
A key design feature is the inclusion of a graphical display and keypad for adjusting settings and interrogating the controller. Increased temperature capabilities counterbalance any unusually high temperatures, both internally and externally.
Eaton-Williams’ own InvictaNET controller ensures maximum efficiency in all modes of operation and at any condition.
Ease of maintenance has not been overlooked, with easy-to-read menu-driven prompts, diagnostics in the graphical display and a sliding chassis providing access to electrical components available across all models.
