Serpentine benders
The HVACR-specific solution
Flat serpentines are used in numerous applications in the HVACR sector (including heating and cooling systems), home appliances, and technologies in the renewable energy sector, to name just a few.
The SERPENTINE BENDERS in the SER family are numerical control machines dedicated to the production of tube serpentines in different materials (Cu, S275, AI, even coextruded).
The configuration of SMI machines may be personalised based on the desired product characteristics. Depending on the material, type of application, and expected quantities, SMI suggests systems capable of feeding, straightening, cutting, and bending from 1 to 26 tubes simultaneously. Product quality, even if very large or with reduced thicknesses, is guaranteed by accompanying units and support when rotating the serpentine coil.
As necessary, SERPENTINE BENDERS can be equipped with shaping units, cap insertion, the introduction of bushing for stiffening, hairline welding in aluminium, tube closing, and taping in completely automatic cycles.
SERPENTINE BENDERS are equipped with an intuitive panel where their operation is guided step by step for programming any processing phase. They are prepared for integration into smart factory systems.
