The precision drawn round grooved tubes are highly refined quality products and are characterised by the following properties:

Cross section of a helical Hygroove tube.

• High heat exchange efficiency
• Lower cost
• Easy to form and bend
• Lower weight
• High corrosion resistance
• High recycling value
• Narrow tolerances
• High surface quality

Other metals with similar qualities exist, but the aluminium used at Hydro combines these qualities in numerous and innovative ways.

The precision tubes are frequently used for the following applications:
• Condensers
• Evaporators
