New cooling Towers The mechanical cooling plant uses a condenser water cooling system. The legacy wet-mode cooling towers on the roof presented an ideal opportunity for renewal with modern hybrid air-cooled units, using water mist sprays only when atmospheric conditions are not favorable, generally when the temperature is greater than 25°C. These air-cooled units use about 10% less electricity and at least 80% less water – both highly advantageous and green friendly. Furthermore, it is possible to run the units to precisely match loads further enhancing savings.
All of these goals had to be implemented in a live environment without impacting dayto-day Gallo Manor background MTN Businesses Gallo Manor Data Center was originally developed in the late 1980's in response to requirements for a high quality environment to be established close to the

Other major changes incorporated included: · extensive and comprehensive on-line metering to monitor and manage power, · extensions and improvements to A-Feed and B-Feed systems to ensure concurrent maintainability · updating of generator controls to allow for no-break load transfers
Sandton financial heartland. Originally, the site started life as a facility for a single major Use with the development of the Collocate-1 space with associated plant-rooms. Throughout the 90s IT boom years and into the 21st century, the growth in need for quality IT space close to the financial heartland for a variety of customers resulted in a number of extensions, including Collocate 3, 4 and 5.The exponential growth and use of the facility was leading to a difficult to sustain model using equipment near “end-oflife” causing a situation where further growth endangered high reliability operations. The R60M contract for the work was awarded to Boron Facilities Management as a turnkey project to be completed during 2011. BoronFM took on this project employing specialist Professionals and Service Contractors all thoroughly experienced in data center operations.

Collocate 2 had previously been used for storage and some field services operations support but had always been intended for data center services. The air-conditioning services piping had been constructed as an extension to Collocate 1 and the close proximity to plant-rooms made this an economical choice.
