CMS offers the most complete range of expanders in terms of sizes, of automation degree, as well as of expansion system. Vertical expanders are more suitable for repetitive productions and high-volume manufacturing with a heat exchangers length of up to 2.7 m., and a maximum number of simultaneously expandable tubes reaching 420. Radiadores Cerezo counts on three of these expanders.
The expansion occurs through the introduction of shaped bullets inside the tubes along their entire length, with the final forming of the bells for the insertion of the bends. Always focused on improving productivity, for vertical expanders we have adopted a system for the automatic replacement of the rods that can highly reduce the machine set-up time, when the thickness of the tube changes; a patented system, with an incomparable flexibility of use.
Horizontal expanders are instead ideal for tube lengths from 3 to 15 m., even for limited production lots, and are characterized by the speed and ease of programming. Radiadores Cerezo has five of these expanders.
The expansion of the tubes may be performed by pushing (for straight tube heat exchangers) or pulling (for hairpin heat exchangers); in this latter case, the process guarantees the execution of tubes of the same length.
In the new generation of horizontal expanders CMS can equip the machine with the camera vision system in order to determinate coil geometry, tube diameter and position of first tube in order to automatically start the production.
The integration of mechanical and electronic expertise, and design, gives unmatched results in terms accuracy, flexibility and reliability.
