Four pipe fan coil units, manufactured by Ability Projects Ltd, Wimborne, Dorset, are being installed by contactors, Mercury Engineering, Dublin, in the new Terminal 2, which forms a significant part of the Dublin Airport expansion project. Due for expansion later this year, the complex comprises an ultra modern 3 storey, 75,000m2 terminal building. Designed with passengers in mind, the new terminal will feature a large and airy check in, baggage reclaim, security, departures and arrivals lounges, connected by a link bridge to the existing terminal 1 building.
Ability Projects are supplying almost 300 mixed Evolution horizontal Trojan and vertical Neptune fan coil units with capacities between 0.7 and 6.5kW (cooling) and 0.5 to 5.0kW (heating) at 50 and 10 Pascals resistance respectively. Operating noise level is set at NR35.
The vertical Neptune units are encased in white Plastisol enclosures with white grilles – the Trojan units are chassis type for installation in false ceilings. All units are being supplied complete with ‘free issue’ Cyclon controls, dc speed controllers and 24V transformers, all fitted by Ability, along with special coils and 28mm drain connections.
Evolution fan coil units utilise the latest ebm-papst EC (electronically commutated) infinitely variable speed, high efficiency DC motor technology and represent a major step forward in fan coil unit technology, which brings a number of significant customer advantages in terms of both energy efficiency and controllability. At a typical fan coil duty point, the Ability EC configuration can reduce electrical input by 50-75% and a typical 2 fan unit will draw 60 Watts when powered by EC motors as against 210 Watts in AC format.
