Leading China Laser-Welded Finned Tube & Industrial Radiator Manufacturer

Changzhou LanChen Environmental Protection Equipment Co.,Ltd.

Established in 2018, Changzhou Lanchen Environmental Protection Equipment Co., Ltd. specializes in the R&D and precision manufacturing of high-performance radiators and specialized finned tubes. Leveraging advanced automated laser-welding technology, our independently developed stainless steel laser-welded finned tubes deliver superior thermal efficiency and unmatched durability compared to traditional high-frequency welded alternatives.

Through fully mechanized laser fusion welding with a penetration depth exceeding 0.2mm, our products achieve a 100% welding rate without fin distortion or surface wrinkles. Designed specifically for severe operating conditions involving frequent thermal and cold alternation, our ultra-compact finned tubes feature a tight fin spacing of ≤1.8mm and fin thickness of ≤0.5mm. This innovative architecture expands the heat dissipation area by over 50% while reducing raw material consumption by more than 50% and overall equipment footprint by two-thirds.

Operating 3 state-of-the-art laser welding production lines with an annual capacity of 400,000 meters, we provide fully customizable solutions—including H-type, longitudinal, inlaid, and composite finned tubes—tailored to your exact OEM specifications.
