Heat transport has been optimized in the helical-shaped inner grooves. The tube's heat transfer coefficient is two times better than that of regular smooth bore tubes. The development of smaller heat exchangers and a reduction in the refrigerant load can both benefit from this higher efficiency.
Different groove depths and geometries satisfy local needs and prevalent refrigerant kinds.
Our specialists strongly advise adding a zinc coating to the tubes of heat exchangers functioning in harsh conditions. When compared to the identical bare tube, this additional layer provides greater corrosion protection and a longer lifetime.
This zinc coating is offered on straight inner grooved tubes and smooth bore tubes.
