Stokvis plate heat exchangers improve DHW provision at university by degrees
An 8-year programme of improvement work by the University of Liverpool on a wide range of buildings on three separate campuses has involved Stokvis Energy Systems supplying plate heat exchangers to ensure the quality and safety of the provision of domestic hot water. Dozens of Econoplate units have been installed in halls of residence, lecture buildings and administrative buildings in the city centre, Sefton Park and Leahurst Campus.
The heat exchangers have been used with buffer vessels or directly to deliver hot water and reduce the risk of legionella contamination.
The university’s facilities-management department has been in overall charge. Senior mechanical engineer Dave Dutton comments, ‘The work is part of our energy-efficiency programme, which has also included the installation of CHP systems and seeking to reduce our storage capacity in respect of legionella contamination.
Stokvis is on the university’s list of approved suppliers, and the Econoplate plate heat exchangers have proved ideal for meeting the sort of demands we have to deal with. In common with certain other types of building, the halls of residence experience some very high peaks in the morning and when lectures finish.’
