The 239m building, developed by Chalegrove Properties, comprises of more than 800 residential apartments. Amenities occupying five floors include restaurants, a leisure centre and gym, a sky-garden and a double-height roof-terrace.

The custom system includes 1,776 of Ciat’s Major Line fan coil units (FCUs) that are being installed by Haydon Mechanical and Electrical. The units will provide an optimal indoor environment to apartments, common areas and facilities, distributed throughout the building.

The energy efficient, four-pipe FCUs were specified in six sizes and configurations to suit the variety of capacities required and situations within the building, which is due to be completed in 2020. Manufactured at Ciat’s global centre of excellence, the units are equipped with bespoke controls and connection sets specified by Haydon.

Paul Graham, technical director for Haydon, who is leading the installation project, said: “One of the biggest challenges for equipment specification was space constraints. Indoor units are installed in ceiling voids to ensure a perfect concealed finish. With limited headroom, this required changes to the design of the fan coil unit.

 “We worked closely with Ciat on a previous project and were aware of the quality of the equipment and the company’s flexible approach. They were able to redesign the Major Line units to fit the available space at Landmark Pinnacle, which required a new lay-out and extended drip-tray. The company provided timely support on site whenever needed, and it was proven to be a very successful collaboration.”

Another key requirement was low operating sound levels, due to the residential nature of the building. The air conditioning units were selected in medium and low-speed configurations to ensure quiet operation.

Air conditioning units were delivered to site in phased batches, timed to coincide with installation stages as the building fit-out proceeded. Before leaving the factory, each was tested for water-tightness, with a certificate of compliance provided as part of its manufacturing record.

Ciat built a support structure around FCU connections to ensure the factory-installed valve sets were protected and supported during transit, so units arrived on site in perfect condition.

Paul Smith, sales manager for Ciat, said: “Landmark Pinnacle is an outstanding new building in the UK’s capital. We are delighted that CIAT was chosen by Haydon to provide the high quality, high efficiency indoor environment required to match the building’s premium residential apartments and facilities.”
