Industrial Aluminum Brazing Furnace for Radiators & Heat Exchangers | Continuous Nitrogen Atmosphere Brazing System
Product Description
The Industrial Aluminum Brazing Furnace is a continuous controlled-atmosphere brazing system designed for the production of aluminum radiators, oil coolers, evaporators, air coolers, and other aluminum heat exchangers.
The system integrates Spray, Drying, Brazing, Cooling, and Control sections into one continuous production process. Operating in a nitrogen atmosphere, it helps reduce oxidation during brazing while providing stable temperature control, consistent heating, and reliable brazed joints.
Key Advantages
1. Precise Temperature Control
Advanced furnace insulation and heating technology help maintain stable thermal conditions. The system provides temperature control accuracy of approximately ±0.2°C, with brazing-zone temperature variation controlled within ±3°C.
2. Adjustable Production Speed
The VFD-controlled mesh belt supports continuous speed adjustment from 200–1500 mm/min, allowing operators to optimize the heating curve for different aluminum components and production requirements.
3. Energy-Efficient Design
Proprietary technology is designed to reduce nitrogen consumption and total power usage by approximately 40–50% compared with conventional systems, helping manufacturers reduce operating costs during continuous production.
4. Integrated Brazing Process
The production line includes:
- Spray Zone: Uniform flux application and removal of excess material.
- Drying Zone: Heating and air circulation thoroughly dry components before brazing.
- Brazing Zone: Radiant tube heating provides controlled thermal conditions in a nitrogen atmosphere.
- Cooling Zone: Natural and forced-air cooling help stabilize brazed joints and support efficient production.
5. Intelligent Control & Safety
An integrated control system provides temperature monitoring, process management, alarms, and safety protection, making daily operation more convenient and reliable.
