NC Air carried out a full system audit and found that an incomplete ring main, under sized air receiver, a generation pressure that was too high and an unmanaged leakage rate were all adding to the increased air demand.
“NC Air were awarded the work” Steve added “they completed our ring main and added new drops, installed an air receiver three times the size of the installed one and lowered the generation pressure from 7 barG to 6 barG. Once they had completed this stage they moved onto fixing air leaks and educating our maintenance staff on the severity of audible air leaks. Now all this work has been completed and we are back to running on the single VSD compressor, which is now at 60% load and this is the lowest it has been since we installed it! I’ve been extremely impressed with NC Air from start to finish and have seen our energy bills lowered by over £30,000 per year along with service costs lowered due to the back up compressor not running unless needed!”
