UK: The first CIAT chiller to be supplied by Toshiba distributor AMP Air has been installed at Queen Mary University of London.
The AquaCIAT 2 Evolution chiller was installed by Basildon-based Hawkes Refrigeration Engineers at the John Vane Science Centre, the world-renowned cancer research centre on the University’s Charterhouse campus.
The installation was part of a major replacement and upgrade of the building’s air conditioning system. It had previously relied on an ageing split system, using a water chiller linked to remote condensing units.
Toshiba distributor AMP was recently appointed a distributor for CIAT following the global takeover of the France-based manufacturer by Toshiba’s parent company United Technologies.
The packaged air-cooled CIAT chiller, with a capacity of 141kW of cooling, is equipped with optional inverter-controlled variable speed pumps for improved efficiency, delivering an EER of 3.09 and SEER of 4.06.
Given the sensitive research environment, the chiller is equipped with enhanced acoustic insulation in order to minimise noise in the vicinity of the installation.
The R410A-based system running on scroll compressors is designed to allow for future expansion as part of a staged replacement process. This includes the use of 6in diameter chilled water pipework and a 10in low-loss header to permit the addition of up to three further Toshiba/CIAT chillers, one of which would be on standby.
The chiller was craned onto its new galvanised steel framework base at ground level alongside the building, under the project management of Hawkes Refrigeration.
