CMS boasts the most extensive and versatile range of expanders on the market, designed to meet a wide array of industrial needs. This comprehensive line represents another significant milestone in the technological development of machines produced by CMS, underscoring our commitment to innovation and excellence. Our expanders are engineered to perform the delicate and crucial tube expansion phase into the fin collars, a process essential for ensuring optimal heat transfer in heat exchangers. The precision and reliability of our machines guarantee that this critical step is executed flawlessly, enhancing the overall performance and efficiency of the heat exchangers.
Depending on the size of the heat exchanger and the quantity of tubes to be expanded, we offer both vertical and horizontal expansion options. For horizontal expansion, in particular, CMS is recognized as the leading manufacturer worldwide, setting industry standards with our cutting-edge technology and expertise. All our machines are designed to operate with either an automatic or semi-automatic cycle, significantly minimizing the need for operator intervention and thereby reducing labor costs and potential for human error.For small coil series and the production of prototypes, we have developed a specialized ball expander, known as the Model MHO, which uses a water-impulse mechanism. This model is extremely user-friendly and requires virtually no setup, making it ideal for quick adjustments and efficient operations. Its simplicity and effectiveness cater to manufacturers seeking flexibility and ease of use without compromising on performance. With CMS expanders, clients can expect unparalleled quality and innovation, backed by our extensive experience and dedication to customer satisfaction.
