Ability fan-coil units reduce commissioning time down to 20%
Well over 300 fan-coil units supplied by Ability Projects for a £13 million refurbishment of an office complex at 110 Cannon Street in London have cut water-side commissioning times by 80%. This 12-storey building provides 7000 m2 of Grade A office accommodation and has been awarded a ‘Very good’ BREEAM certificate.
The Ability 4-pipe fan-coil units are all fitted with a Delta BACnet controller and Marflow valve-train assembly — complete with 2-port pressure-independent valves, combined control and commissioning valves, flushing bypass, isolating and drain valves, and a flow-measurement device.
All valve flow rates were uploaded into the controller before delivery to site. Changes can be made from the BMS rather than at the units themselves. Ability also supplied self-balancing valve software to reduce water-side commissioning time, as well as alarm switches linked to the BMS.
