RODOMACH Pillow Plate production line

RODOMACH Pillow Plate production line was built in 2020. Pillow Plate heating and cooling coats are created by joining two sheets of stainless steel together using laser spot welding. Once a circular contour has been created, the sheet is pumped hydraulically resulting in so-called ‘pillows’. The large heat exchange and flow area increases heat/cold transfer and reduces the heating/cooling time of the product. Suitable thermohydraulic properties enable the design to be used under high pressure conditions and in a wide range of products, i.e. heat exchangers, filter housings and air-conditioning chambers.

The Pillow Plate heat exchangers production line consists of the following parts:
1. slitting line for sheet metal with a maximum thickness of 1.5 mm
– sheet metal decoiler
– infeed and guide system
– sheet metal straightener
– perforation unit
– guillotine
– roller conveyor
2. slitting line for sheet metal with maximum thickness of 6 mm
– sheet metal decoiler
– infeed and guide system
– sheet straightener
– sheet metal foiling system
– guillotine
– roller conveyor
3. RODOMACH laser welding machine (2 pcs.)
