VAB Multi-Chamber Modular Furnace The VAB multi-chamber furnace is a modular unit designed to be customized to meet the specific requirements of the customer, particularly for high-volume, high-capacity production. The underlying concept of the process, which utilizes no flux (no flux technology) and significantly enhances environmental safety, mirrors that of a chamber furnace. However, the multiplication of chambers allows for a substantial increase in capacity, achieved, for example, by incorporating additional heating or post-cooling chambers, resulting in time savings.

Vacuum fluxless brazing offers the advantages of eliminating flux inclusions and designing blind cavities, winding paths, and small transitions in brazed parts without the detrimental effects associated with flux removal and trapping after brazing. Precise temperature control makes it possible to leverage the narrow soldering temperature range available for this type of material, achieving excellent solder joints. The blast furnace is additionally an all-in-one device capable of employing multiple solutions (de-oiling, preheating, brazing, sub-cooling, cooling, and sub-cooling).
