Imofa, contractor, AHU, air handling unit

When the refurbishment of Colchester Town Hall, dating from 1898, included improved disability access, the installation of a disabled lift came at the expense of the plant room and air-handling plant providing heating, ventilation and comfort cooling to the Jury Room, Mayor’s Parlour, members and committee rooms. However, Imofa UK rose to the challenge of removing existing plant and instal­ling a new unit on time.

Fujitsu, Eurofred, air conditioning, VRF

When more air conditioning was needed at Lord’s Cricket Ground, CER, which has carried out air-conditioning and refrigeration work at the ground for the past eight years, was called in. The £225 000 contract was for the offices of the England & Wales Cricket and a pair of restaurants in the Mound Stand. The equipment was supplied by FG Eurofred and Fujitsu distributor FM Air Conditioning. All the work had to be completed in a very tight time frame to fit into the schedule for Test Matches and Middlesex games.

Smith's Environmental Products, fan convector, space heating

As part of the conversion of a 19th-century property in the ground of Brocksford Hall in Derbyshire, two 3.7 m radiators have been replaced with a single fan convector form Smith’s Environmental Products. Anton and Marjorie Brooks were converting an upstairs studio into a bedroom with en-suite facilities and came across Smith’s at an exhibition, which recommended a Staccato low-level wall-mounted fan convector with thermostatic control and coloured front fascia — red for this project.
