Company Profile:

Centrifugal, Diaphragm, Reciprocating, Roots^® and Twin Screw compressors.

Other manufacturers, consultants and agencies may be able to offer different aspects of compressors and their uses. However, there are none that can draw on the scope, depth and breadth of our experience, or provide the support we offer in selecting and customizing a product to exactly ﬁt project needs. Our unique combination of knowledge and outstanding engineering skills means that every customer has access to an individual, precisely tailored response.

With more than a century of applications experience and a range that covers every major technology, we can advise on, design and supply the right compressor for virtually any situation and we offer an unequivocal commitment to support, spares and service for the lifetime of every compressor we sell.
