Seamlessly drawn round plain copper tubes in level-wound coils (LWC) are a cost-effective pre-material for the manufacture of heat exchangers, electrical water heaters, air conditioning and refrigeration, and cable lugs.
In addition to plain tube, LWC can also be supplied with an internal groove. Predominantly applied in the field of evaporators and condensers, inner grooved tube offers an improved heat transfer due to the fine structure.
Coils can be supplied with or without cardboard reels depending on the customers de-coiling needs. Individually banded and safely stacked on a pallet, considering customers specific restrictions.
