CELEBRATING 150 YEARS OF INNOVATION

In 2011 Holroyd marks its 150th year of precision engineering and

manufacturing. Throughout its history, Holroyd has continuously

innovated and to this day stands at the forefront of high precision

specialist machine tool and parts manufacturing. With an unrivalled

pedigree, highly developed knowledge and proven expertise, Holroyd is

the ideal partner for companies, both new and fully established, engaged

in the screw compressor industry on a global basis.

From the early days of screw compressor manufacture, with the first

dedicated milling machines to produce helical profiles, Holroyd has

developed a range of leading technologies, from tool and cutter to

finished part grinding. Today the company is preparing to launch its

latest innovation, the Zenith 400 profile grinding machine, which will be

introduced at EMO 2011 in Hannover in September. This will be another

milestone in a long history of class-leading developments, enabling

extraordinary precision and manufacturing productivity.

The parts supply part of the business, Precision Components Limited,

continues to invest and innovate and has also been at the forefront of

screw compressor rotor manufacture for more than 50 years. Working

closely with customers to design and produce all manner of helical forms,

specialising in the parts for Compressors, PCL has the capacity to

produce prototypes and/or large production runs to suit all needs.
