Driving out debris K
een to protect all its HVAC equipment from airborne debris and to maintain its efficiency, the Central Middlesex
Hospital sought a solution for all its 28 locations adjacent to London’s A40.
RABScreen, the external air intake screen specialists, together with distributor GVS Filtration and their client Bouygues put forward a successful bid in a competitive tender and the team then subsequently fully surveyed all the hospital locations.
As a hospital project, much of the work had to be completed at weekends, and there were several problems which needed to be addressed: 10 of the supply ducts were drawing air from high level louvres; access required scaffolding which would make on- going maintenance very difficult; and internal duct access was also difficult.
The hospital maintenance team was looking for a mesh screen that could be inserted into existing ductwork then simply withdrawn for future maintenance. For RABScreen director Richard Betts, this was not a problem. By working with one of its partner companies,
RABScreen external air intake screens have been fitted to AHUs at the Central Middlesex Hospital. The supply duct split to allow installation of filter box with slide in/out RABScreen (below). Left: The GVS BACTICELL sits behind the RABScr een’s mesh
AJM Ventilation, the team was able to modify the ductwork to receive new filter boxes. The RABScreen solution was installed within the supply filter box to make screen insertion easier.
Now the local airborne debris created by London’s A40 and the surrounding industrial area is kept away from the disposable filters increasing their lifespan by as much as 60%. This front line protection allo wed the introduction of the highly efficient GVS
BACTICELL which sits behind the RABScreen’s mesh material, the GVS BACTICELL improves efficiency and copes with high pressure differentials between changes. These BACTICELL screens are expected to reduce replacement costs dramatically with the next filter change not expected until August 2019. Nick Shackleton, director at GVS Filtration commented: “It was a great solution for the customer. All of the AHU plant is now
protected by the washable RABScreen and the long lasting BACTICELL . AJM Ventilation’s expertise in ductwork meant that the contract was fulfilled on time and within budget.”
