An industry leading global life science manufacturer and high-end medical moulder was looking to improve the energy efficiency of the chiller plant across their facilities. Their chillers are needed to provide precise and consistent process temperatures to maintain product quality and lower wastage.
Following a site visit to carry out a survey and understand the manufacturer’s specific applications, facilities and temperature needs, we received their official RFQ.
To meet their unique requirements, we specified:
384kW Aptus Free Cooling Chiller
This chiller unit operates with ozone friendly R410a refrigerant and boasts an exclusive dedicated coil, hermetic scroll compressor and is resistant to external wear. In summer, when external air temperatures are higher, this chiller unit will work as a normal chiller would, with the compressors running.
In mid-season, the unit will offer partial free cooling – reducing the operation of the compressor and energy required to run. Most importantly, in cooler ambient temperatures, thanks to the Free Cooling coil, the compressor will not be required to run – providing 100% Free Cooling.
1.1mW Imperium Air Cooled Chiller
This externally sited 14 off die-cast aluminium axial fan unit with semi-hermetic screw compressor was required for use on a separate building and offered the customer reduced life-cycle costs and allowed ease of communication through included Modbus interface.
Magnus Air Cooled Turbocor Chiller
This high efficiency & extra low noise chiller, running on R134a refrigerant, was selected as it offered an impressive operational saving of £55K a year over the inverter screw option and a payback period of 15 months.

European Cooling Plant Improvements
Having successfully completed these projects in the UK, we were asked to support a new cooling project to reduce energy consumption at another one of their facilities in Europe, whereby 2 externally sited air-cooled chillers were needed to provide cooling to a process line.
Our solution was to deliver, install and commission 2 x 900kW high-efficiency Imperium inverter screw chillers using the low GWP R513a refrigerant. The reliability of the inverter screw, superior part load performance, low GWP of the refrigerant, low refrigerant charge flooded evaporator and inclusion of electronic expansion valves (which alone save around 9% energy) offer significant energy savings.
The completion of these recent projects has meant the life science manufacturer has significantly reduced their energy consumption and increased their sustainability through the cooling plant upgrades – 5 chillers complete with pipework at 2 production sites, across 2 countries – saving them 10’s of thousands of pounds annually.
