When five large and ageing supply and extract air handling units needed replacing, the site technical manager contacted AHU specialists, ECEX.
One of ECEX's expert surveyors undertook a detailed survey of the AHU's. It became evident that refurbishment and upgrade of the Toilet Supply and General Extract units would be a more appropriate option than replacement due to site logistics, downtime considerations and cost.
A full scope of works was agreed for the replacement of three units and the comprehensive refurbishment and upgrade of the others, including corrosion treatment, replacement of dampers and actuators, the replacement of the existing belt driven fans with new EC plug fans and a full deep clean.
The works were completed to the agreed programme by ECEX's skilled site team without disruption to site activities.
