The micro grooves inside this new aluminium tube are optimized for the best possible refrigerant-side heat transfer yielding the following benefits:

Typical evaporator with straight Hygroove tubes

• Price per length of 3/8” or 9.52mm (Al tube is 40 % less than copper)
• Weight per length of 3/8” or 9.52mm (Al tube is 40% less than copper)
• Easy to form and bend
• High recycling value
• Narrow dimensional tolerances
• High surface quality
• Less material spring back vs. Copper (Ensuring a better bond between tube and fin during expansion)
• Same thermal expansion coefficient as Al fin stock (The bond between tube and fin will be constant regardless of temperature)
• Corrosion resistant to formic & acetic acid liquid/vapor (Fumes exhaled from building materials in new constructions)

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
