CBM PARTNERS were commissioned to carry out an air leak survey across a food production Site over a 3-month period. This article is a direct-excerpt from the survey report.
The program included our consultant fixing as many leaks as possible during the survey; our focus being on to save energy/money not write a report!
The stated objectives were to photograph and report on any leaks found during the survey to aid with defect rectification. We repaired air leaks during the survey for ‘quick wins on cost savings’ (eg tighten fittings, replace minor parts).
32 of the leaks found around the site had a loss of over 1.8ft^3/min resulting in over 60% of the total wastage in air.
