A council-run leisure pool in Suffolk was faced with an inefficient, failing air handling system.
The air handling units (AHUs) in question served as the main supply and extract equipment and, having been installed approximately 30 years prior, had reached the end of their economic life and were in need of replacement.
The council wanted the facility to be at least partly operational while work was carried out, with minimal disruption for users.
Our HVAC Services team were commissioned to perform the upgrade, which commenced with the decommissioning and disassembly of the original AHUs; each one was cut down to sections small enough to be safely removed from the plant room before being taken away for recycling.
Getting the AHU into the plant location presented a challenge as the only entry point was via a standard single doorway. To overcome this problem, Gibbons designed and manufactured each part of the AHU, fans, dampers and coils to be in component form and assembled them inside.
New plug-type fans were fitted to energy-efficient motors, which were paired with ABB HVAC variable-speed drives for additional savings during non-peak times. The new units were built on the existing concrete slab and matched as closely as possible to the original duct connections. Upon completion, each AHU was tested and the fans dynamically balanced.
This turnkey package was fully managed by Gibbons and delivered to programme and on budget.
