High Vacuum Aluminum Brazing Furnace

Description:

High vacuum aluminum brazing furnace is applied for vacuum brazing of material like heat exchanger,air evaporator,condenser,radar grid antenna,wave-guide tube,etc.

Technical Feature:

1. The aluminum brazing tube furnace structure is horizontal,single chamber and loading horizontally.

2. The furnace hearth consists of several zones,wide nickle-chromium alloy heater and multiple layer stainless steel heat steel heat insulation,which has a good temperature uniformity.

3. The vacuum system inlet is configured with gas condensate steering device and filter collection device,preventing welding vapor polluting the vacuum pump.

4. Unique rear insulation technology assures larger radiation area and better insulation performance.
