High Vacuum Aluminum Brazing Furnace

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

Technical Features
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 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.

Optional Configuration of High Vacuum Aluminum Brazing Furnace
1. Furnace door type: on-line/off-line, vertically up and down, rotating
2. Vacuum pump and gauge: Foreign brand/high-quality Chinese brand
3. PLC: OMRON/Siemens/Mitsubishi
4. Temperature controller: SHIMADEN/EUROTHERM/Honeywell
5. Thermocouple: S type, K type, K type
6. Recorder: Paperless recorder/paper recorder
7. HMI: Simulation screen/Touch screen with industry computer
8. Electric component: high-quality Chinese brand/Schneider/Siemens
