Project duration: 6 Weeks
Scope of Works:
The brief was to replace the existing Searle manufactured dry coolers to give an increase in cooling capacity and a more energy efficient operation. The consultant for the project designed the application, and then in conjunction with ABI the equipment was specified to achieve the solution. ABI then undertook and managed the relevant phases of the project. By replacing the pumps abi were able to deliver in the region of 50% added heat rejection capabilty, and by choosing latest technology EC inverter driven fans an actual decrease in operating costs was an added bonus.
Due to the fact that the building wouldn’t cope with losing 50% of its heat rejection capabilities, it was decided that one of the new proposed dry coolers would be installed temporarily before removing two of the old ones as pictured here.
The old concrete pads were sinking due to poor foundations, so following validation the client and consultant decided that a reinforced concrete raft would be laid to avoid any further subsidence and thereby future proofing the proposed installation.
Once the concrete was dry and the foundations had been checked, two of the new dry coolers were craned on to the first part of the raft before the pipework was fabricated accordingly onto the existing Flow and Return services.
Once the first two DC’s were operational, the above process was repeated for the second half of the concrete “Raft” thereby allowing further upgrades to the water circulation pumps, building energy management controls, drainage, protective barriers and pipework insulation, finally completing the project in approx 6 weeks total.
The site, and more importantly, the data hall, remained open and fully operational throughout the duration of the project keeping approx twenty Indoor AHU’s functioning correctly. A most important criteria of a 24 hour communications equipment environment.
