Diffusion fan-coil units for Walkie-Talkie

Very low specific fan powers led to Diffusion fan-coil units being installed in the Walkie-Talkie building in London.

Diffusion has supplied over 2000 Eco H270 EC DC fan-coil units for the Walkie-Talkie building at 20 Fenchurch in London. An extremely low specific fan power was specified (0.19 W/l/s) for the project — to be achieved at an external system pressure of 30 Pa and at NR35 with all units running.

Project-specific witness testing demonstrated that specific fan powers of 0.14 to 0.17 W/l/s would be achieved within the NR35 noise requirement on standard model selections without oversizing.

Diffusion provided volumetric, acoustic and thermal-performance factory testing according to relevant standards to Land Securities, Canary Wharf Group, Hilson Moran, Chapman Bathurst, Atelier Ten and MH associates to demonstrate that all unit selections met or exceeded the specified requirements.
