VAB Multi-Chamber Vacuum Furnace

The VAB-type multi-chamber vacuum furnace is a continuous furnace designed for brazing aluminum components in multi-batch quantities, featuring a rectangular housing. It comprises multiple chambers, each aimed at reducing process duration.
In the basic configuration of such a furnace, there is a loading chamber serving as a preheating and potentially a de-oiling chamber.
Subsequently, there are the process, discharge, and cooling chambers. All chambers, except the cooling chamber, are closely interconnected, facilitating the transportation of parts between chambers under vacuum conditions.
The loading, process, and unloading chambers are equipped with a multi-zone heating system, enabling precise control and temperature regulation in each chamber.
Each chamber has an independent drive mechanism.
The heating chamber consists of removable metal panels housing heating elements made of heating tapes.
For easy access to the furnace, individual chambers are equipped with inspection doors allowing quick access to the furnace interior without uncoupling the chambers.
Soldered parts are placed on fixtures in the form of brazes, suspended from rails.
The furnace’s modular design allows for expansion with additional preheating chambers to further reduce process time and seamless integration with an automatic conveyor system operating in a closed system.
The VAB multi-chamber oven addresses the needs of customers seeking the highest efficiency and accommodating high production volumes. The capability to utilize a variable number of chambers enables the unit to be customized according to customer requirements.
