Description
The cutting-edge horizontal high vacuum furnace, featuring gas cooling, stands as the pinnacle for
brazing aluminum-alloy heat exchangers
. It seamlessly accommodates diverse loads and part configurations.
The unique chamber and resistor geometry ensures that each heat exchanger pack is exposed on both sides to the radiant surface of high-efficiency resistors. This design facilitates swift cycles and
ensures uniform heating throughout the process
.
The cycle operates automatically
, eliminating the need for operator supervision. Precise temperature and pressure settings can be predetermined.
Upon reaching the brazing temperature and ensuring sufficient time for
complete melting at the coupling surfaces
, the furnace initiates a first natural cooling phase under vacuum. Subsequently, a second step is performed using nitrogen.
The resistor and thermal chamber's geometric configuration was carefully crafted to achieve
high heat exchange rates
and
uniform temperature distribution
.
