TWC Invac of Warsaw, Poland, received an order from customer in Spain for a car-bottom, high-vacuum furnace for special brazing applications. The furnace’s rectangular all-metal hot zone accepts loads of 1,500 mm x 1,500 mm x 1,500 mm. Six temperature control zones will assure optimal temperature uniformity. The furnace’s control system is based on a Stange 607 industrial controller and an ECS2000 interface. A stainless steel chamber will use conflate seals wherever possible to minimize leak-in.
An external gas cooling system is comprised of a 45-kW blower and heat exchanger in separate stainless steel housing and molybdenum nozzles surrounding the workload. A dry mechanical pump and Roots blower are also part of the installation. TWC Invac will also supply support in brazing process development.
