Furnace Capital Equipment Selection

We are able to advise on the selection and specification of any furnace capital equipment that you want to purchase. We can give advice for not only your current requirements, but we can also provide you with careful planning to make sure your selection is as future-proof as possible. Having a wealth of contacts we are not tied to any particular manufacturer.

Having a wealth of practical experience we can further advise on installation, running and maintenance.

 

Others

With our extensive knowledge we can also advise on vacuum brazing of many other applications both new and old with the rounded experience of not only the metallurgy but also the commercial process and considerations needed for engineering facilities.

We can also assist you with alloy selection and cross-referencing of technical specifications to make sure you have the correct alloy.

If you require cross-referencing of specifications or translating the requirements of an unfamiliar specification, we have a wealth of experience and expertise helping clients with such enquiries. Please call or email us.
