Case Study 1 - Clean Room Installation Services

The efficiency of the next generation of civil jet engines requires components to be manufactured to tolerances of up to 10 microns. Components and machinery will vary in size by substantially more than this as factory temperatures change during the day.

State of the art machine tool and lathe equipment, designed especially for this, needs to work in a fully enclosed, clean and temperature controlled environment.

Whatever the external conditions and whatever machine process is being carried out, the room temperature has to remain in the preset standard range of + or -1°C.

Parts to be machined and tools to be used have to "cure" in the same environment as the machinery for at least 24 hours.

Clean Room Installation Services worked with the production engineers to design the most economic enclosure and air handling system to meet these requirements. The initial installation, to enclose one machine, 6m high x 13m wide and 20m long complete with all service and plant and with goods and personnel airlocks was installed in 1997 and has operated none stop since. More recently, three other larger areas have been installed on the same site and the original area has been extended to double the size to accommodate two machines.

A large clean room area to manufacture complex aero engine gear boxes - 476m² x 5m high with internal crane systems, epoxy flooring and all the associated plant and control systems has also recently been installed.
