Harwich Office Upgrades - HVAC

Trinity House have HVAC systems installed in two buildings, known as the main office (3 floors) and buoy yard (2 floors), at their Harwich site. These systems have been operational since 2006 and are maintained on a regular basis. The system consists of a mix of floor wide arrangements with fan coil units in the roof space as well as dedicated room based independent units. All items are from the Daikin range and can be centrally controlled and configured via a portal.
