304/316L stainless steel spiral 32mm laser welded fin tube chemical heat exchange equipment

The laser welding process enables the production of completely individual, 100% gap-free stainless steel finned tubes for every requirement.

• 100 % flexibility
  freely combinable of tube and fin material
• 100 % gap free                                                                                                       
• because of 100 % laser welding of fin and tube
• Increased heat transfer – high performance
  because of 100 % laser welding of fin and tube
• High corrosion resistance against aggressive media
  because of flexible use of different material combinations
• High reliability with highest output
  because of inseparable 100% laser welding
• Easy shaping of the finned tubes
  because of simple bending and coiling of the finned tubes
• Compact heat exchanger design
  because of high outside heat surface of the finned tubes
• Low heat exchanger weight 
  because of reduced tube numbers
• Standard tube materials
