CerroGroove® is our internally grooved copper tube. The precision of our tubing provides superior heat transfer capability. CerroGroove allows for a more efficient cooling unit while reducing both energy consumption and costly demands from the unit’s other components. This enables air conditioning OEM's to lower their costs through the production of smaller, more efficient cooling units.

CerroGroove

CerroGroove® Tube

  • One of the most precise, thin-wall, internally grooved copper tubes in the industry. Available in sizes ranging from 5/16" to 1/2".
  • Level wound coils are provided in light anneal temper.
  • Internal helical grooving substantially increases overall heat transfer capability.
  • CerroGroove forms bends and expands similar to a smooth tube.
  • Cold rolling pilger processing produces extremely uniform wall thickness – ensures superior quality and precise weight per foot.
