Structured tube beats smooth-bore tube

ERK Tube technology means reshaping smooth-bore tubes, so evenly placed dimples in the tube wall form. Thus, swirling is created in the flow medium in areas close to the wall.

This effect positively influences:

• heat transfer
• degree of fouling

It also has advantages in the following points:

• material usage
  
• size ratio
  
• material properties
  
• manufacturing and shipping costs
  
• material stability
