Epson Case Study

Epson Telford Requirements

The 42,000 m2 plant in Shropshire is Epson’s sole European manufacturing site and employs 1,100 staff involved in plastic injection moulding and ink cartridge assembly, in clean rooms where continuous system operation requires a 24/7 precise cooling capability that is both efficient and reliable.

Air conditioning plays a major role in the Epson manufacturing facility. Computers and machinery in the clean rooms need to be kept at 22°C to remain in optimum working condition. Keeping them at this precise temperature is difficult to maintain in a room filled with people and machinery. Air quality is also a major priority making it imperative that all the components and equipment are free from dust and debris from the air.

Design Criteria

Two standard Airedale chillers have been supplying cooling to all indoor units at Epson, with close control units providing reliable and precisely-controlled air conditioning in Epson’s two clean rooms. Ceiling cassettes have also been installed in other areas for staff comfort.

Now, with the cooling load on site increasing and new free-cooling technology available from Airedale, forward-thinking management at Epson has superseded the two existing Airedale chillers with three Ultima FreeCool chillers that will expand system capability at the same time as significantly cutting energy costs.
