Key Features & Advantages
- 100% fin-to-tube bond for exceptional heat transfer efficiency
- Excellent corrosion protection on base tube
- Easy cleaning with high-pressure water jet without fin deformation
- No galvanic corrosion between tube and fins
- Vibration resistant and thermal stress resistant
- Higher heat transfer performance throughout product lifespan
- Continuous outer sleeve eliminates contact loss issues
Manufacturing Process
A carefully degreased core tube is fitted into an aluminum primary tube. This assembly is fed into the triple-spindle finning head where three special multi-disc packs extrude the aluminum tube into helical high fins while reducing the inner diameter to create firm pressure contact with the core tube.
