Client: GlaxoSmithKline
Type of works: supply and installation of new cooling towers and retrofit of existing units.

The GSK Plant required both new cooling towers and retrofit of existing units. In addition to the objective of operating efficiency, the client required that the installation avoid disturbing the plant’s residential neighbors.

With the proximity of Facility 1 to apartment houses in mind, Jaeggi worked with GSK to ensure a focus on acoustics and plume abatement, as well as water conservation and energy efficiency for Facilities 1, 2 and 3. The GSK project required three unique industrial cooling installations: one new installation and two retrofits.

The primary goal for the retrofit projects was to upgrade the existing dry coolers to evaporative coolers. In order to improve the capacity without the typical high water consumption of evaporative products Jaeggi hybrid dry-coolers were installed. The retrofit for Facilities 2 and 3 required four 2.4 / 5.45 units. The new installation called for adding four hybrid coolers type 2.4 / 9.6.

The GSK Biologicals complex now houses eight Jaeggi hybrid coolers with a combined cooling capacity of 11 MW (2,500 evaporative tons). The Jaeggi hybrid dry-coolers ensure an efficient operation of water cooled chillers for the air conditioning of the dust-free rooms essential to the continued production of GSK’s life-saving vaccines.

Individual cooling units are operated by HybriMatic^® controllers with Rockwell components. In several hydraulically separated loops, the operation of each cooler is optimized by the integration of the HybriMaster^® control. The GSK Biologicals facility enjoys all the advantages of evaporative cooling, without the typical high water-consumption. In consideration of the residential neighborhood, the low noise and plume abatemen thas truly made Jaeggi the ideal choice for this inner city installation.
