Continuous Aluminum Brazing Line for Radiators & Heat Exchangers | 380V Nitrogen Shielded Brazing Furnace

Continuous Aluminum Brazing Line for Radiators & Heat Exchangers | 380V Nitrogen Shielded Brazing Furnace

Product Introduction

The Continuous 380V Nitrogen Shielded Aluminum Brazing Line is an integrated production system designed for high-volume brazing of aluminum heat exchangers, including automotive radiators, condensers, intercoolers, evaporators, and other aluminum heat transfer products.

Using a controlled nitrogen protective atmosphere and electric resistance heating, the line helps minimize oxidation during brazing and supports consistent, reliable joints. The adjustable mesh belt speed of 200–1000 mm/min and rated working temperature of up to 650°C allow the process to be adapted to different product sizes and production requirements.

The complete system integrates flux spraying, drying, brazing, cooling, and electrical control into a continuous production flow. Optional degreasing and water cleaning sections are also available for customers requiring additional pre-treatment.

With a standard 10-meter furnace muffle, approximately 700 kW adjustable installed power, CE certification, and overseas engineering support, SUNHOPE can configure the brazing line according to your products, production capacity, and factory layout.

Key Advantages

Continuous & Integrated Production
