SPC restores heat-recovery performance at Glasgow hospital

Replacement heat-recovery coils from S&P Coil Products (SPC) for are recovering over 6 GWh a year in ventilation plant at Glasgow Royal Infirmary. SPC also supplied steam frost-protection coils for the high-level main ventilation intakes. The heat-recovery coils are recovering over 1385 kW at the rated total ventilation rate of 111 m3/s, reducing CO2 emissions by about 1200 t a year through gas savings.

Having worked effectively since 1992, a number of the existing SPC heat-recovery coils needed replacing because of loss of performance resulting from repair work to rectify frost damage.

Owing to the location of the installation, SPC and distributor Heating Appliances & Spares Ltd (HASL) worked closely with contractor Taylor & Fraser, carrying out site surveys prior to the replacement of the existing heat-recovery coils.

Access to the main plant room is limited, so replacement coils were supplied in modules and sizes to minimise site work during installation. The frost-protection coils were supplied with integral filter frames to enable standard filter pads to be fitted and maintained despite the limited access. Heat-recovery coils are piped to a series of extract coils in the main ward block.

To protect against extremes of temperature during operation and aggressive contamination from a nearby motorway, the new frost-protection coils have widely spaced aluminium fins protect with a Blygold coating with a 5-year guarantee against corrosion and performance loss.
