Case Study
AES complete Major Airport Fire Station installation.

CASE STUDY - DUBLIN AIRPORT FIRE STATION
Background
In September 2007 AES were approached by the Dublin Airport Authority Fire section requesting to submit proposals for the provision of a bespoke exhaust fume extraction systems within the facility. The fume problem was exacerbated by the high vehicle movements within the large 12 bay station as the vehicle exhaust fumes were being transmitted through the bays and building fabric into the offices, canteen and accommodation areas. This posed potential health problems for all staff employed and a solution was sought to eliminate the problem at source.
As with all Airport fire stations Dublin is 100% operational serving the airport and the surrounding area it was vital that the proposed systems met certain design criteria’s that set the project apart from standard fire station projects. The station had a mixture of single and double exhausted vehicles which exited the vehicles in differing areas. A secondary simple standard system was required for support vehicles parked within the station complete with connection hoses and clamp on nozzles.
The Brief
1. The prescribed system must be designed cover the current fleet and any future RIV (Rapid Intervention Vehicles).
2. The system must automatically connect to the system without operator intervention or provision of access to 2.5m high exhaust pipes.
3. The system must automatically sense the arrival of any incoming or outgoing engine and operate the fan. Also it must run on for a set time to ensure that all fumes are exhausted from the track area.
4. It must be flexible to cover for and differing vehicles coming into any bay at any time.
5. The extraction fans must be mounted externally and not significantly increase the background noise to the station.
6. The systems must eliminate fumes from leaking into the work areas and extract above the roofline.
7. Interconnecting ductwork located at high level was appropriately sized to maintain a column air velocity within the network and maintain 100% utilization if required.
8. The system must cope with vehicles driven from the rear doors or reversed in if required.
9. Provide a turnkey solution including all control wiring and extraction fan electrical works.

The Solution
AES fitted 12no. VSR (Vertical Sliding Rail) within the 8no central bays to provide extraction to upto 4no. Double exhausted vehicles. Each rail is complete with 3no. flow sensors and PCU1000 electrical controllers,. 12no. FBC/6 special exhaust adapters supplied as loose equipment. They will be required to be fitted to your vehicles. All adaptations to vehicles will be carried out by others.
3 no.TEV 765 Fans (9,600m3/h free blowing) roof mounted complete with silencers. Full turnkey electrical installation, COSHH testing and commissioning on completion
Fixed Points System
1no. TEV-3110 (3100m3/h) fan complete with 2no. fixed points with 7.5m long x 125mm diameter high temperature crush resistant extraction hose complete an REGD 125mm – 160mm rubber/steel clamp-on type nozzle for connection to the vehicle.
The system is sized for future expansion if required.
The system was commissioned in June 2008 and fully complies with the design brief, providing effective fume extraction from the work area.
