Purpose: This machine is specially designed for expanding the pipe of heat exchanger coils, a key process in the production of
Condenser & Evaporator Machines. It works in coordination with equipment like the
Coil Bending Machine, ensuring the expanded coils meet the precise dimensional requirements for subsequent processing, thus guaranteeing the heat exchange efficiency and overall performance of condensers and evaporators.
Main Parameters & Design: The machine supports copper tube diameters ranging from Φ7mm to Φ25mm, covering most common specifications in heat exchanger production. Its expansion length can be customized according to the buyer’s specific needs, offering strong flexibility. With an expansion speed of 5-11 meters per minute, it balances efficiency and precision.
In terms of design, it is available in one, two, or four-tube configurations, adapting to different production scales and efficiency requirements. When paired with the
Coil Bender, it forms a complete processing link for heat exchanger coils, greatly improving production continuity and reducing processing costs for manufacturers.
