Alongside our established and robust materials supply chain our array of in-house machining and process capabilities enables us to manufacture the highest possible quality heater units. Working with high purity ceramics and special metals such as tungsten and molybdenum we manufacture designs from simple plates through to complex assemblies with thousands of sub components. Our quality assurance system is essential to deliver to the exacting tolerances and very tight performance bands of heater units and assemblies. With heaters being a consumable product we offer an onsite service facility with a global footprint. In addition to this function we also offer a repair and overhaul service for used assemblies.
