Our fin tube machines produce spirally crimped finned tubes: the fin strip is wound in a continuous spiral around the base tube under tension, and the machine crimps it to form interlocking ridges for a secure mechanical bond without welding. This process delivers high heat transfer, consistent fin quality, and durable attachment under thermal cycling and vibration. PLC-controlled operation allows adjustable fin height and spacing at production speeds up to 25 m/min for use in heat exchangers, boilers, radiators, and cooling systems.
