250mm Aluminum Brazing Furnace | Continuous Radiant Heating Furnace

The 250mm Aluminum Brazing Furnace is a continuous tunnel-type furnace designed for efficient aluminum brazing of radiator cores, condenser cores, heat exchangers, and other aluminum components.

The furnace uses radiant tube heating to provide stable temperature control with an accuracy of ±3°C. Its four-section design integrates heating, spray drying, brazing, and air cooling into a continuous production process, reducing manual handling and supporting consistent brazing quality.

With a maximum workpiece height of 250 mm, an operating temperature of 650–700°C, and an adjustable mesh belt speed of 200–1500 mm/min, the furnace can be configured for different workpiece sizes and production requirements.

A PLC control system, stainless steel construction, and nitrogen-protected brazing atmosphere make it suitable for continuous industrial production.

Radiant tube heating and PLC control maintain a stable temperature with ±3°C accuracy, helping achieve consistent brazing results.

The mesh belt speed can be adjusted from 200 to 1500 mm/min to match different production rates and workpiece requirements.

Heating, spray drying, brazing, and air cooling are combined in one continuous system for a smoother production workflow.

Suitable for automotive radiators, condensers, heat exchangers, and aluminum radiator cores.

The stainless steel structure is designed for continuous operation, while furnace dimensions and configuration can be customized according to production requirements.

The furnace is suitable for:

• Automotive radiator cores
• Aluminum condenser cores
• Heat exchangers
• Plate-fin heat exchangers
• Other aluminum brazing components

It can be configured according to workpiece dimensions, production capacity, brazing requirements, and factory layout.
