General
The PVA TePla high-temperature heat treatment systems are designed for process temperatures up to 2.200 °C - depending on customer-specific requirements. Special attention is paid to a robust design where safety and efficiency are paramount. Demand-oriented loading and automated handling systems may be integrated through 3rd party solutions providers.
Vacuum heat treatment equipment with graphitic resistance heating
The COV vacuum plants can be variably and customized with regard to design, useful chamber size, vacuum and working temperature. These plants are double-walled, water cooled, steel vessels and equipped heating elements made of graphite or carbon fiber composites (CFC).
The COV systems are robust, with outstanding temperature uniformity typically calibrated to within ±3 °C temperature deviation throughout the vessel. The COV system is ideally suited for quenching and tempering, and brazing processes on reaction-insensitive materials.
Vacuum heat treatment equipment with metallic resistance heating furnaces
Our MOV plants are resistance-heated heat treatment furnaces with heating elements made of refractory metals such as molybdenum or tungsten. The heat is transferred by radiant heat from the heater directly to the product to be treated. MOV systems are suitable for universal heat treatment processes which require a high-purity and carbon-free furnace atmosphere, for demanding materials and for manufacturing and laboratory applications.
Thanks to PVA‘s all-metal design - cold-wall furnaces with water-cooled double shell made of stainless steel and multi-layered metal sheets and foils for thermal insulation - the MOV plants are predestined for operation with high vacuum.
Application areas and markets
Typical areas of application for vacuum heat treatment are high-tech industries, since high purity gas and high vacuum is required both in the manufacturing process and for the materials themselves. The various applications such as heat treatment, degassing, bright annealing, CVD coating, or vacuum and inert gas brazing are used in these industries, among others:
