Results are presented here from an experimental investigation on tubeside condensation and evaporation heat transfer that took place in three Vipertex® stainless steel enhanced heat transfer tubes (1EHT-2, 2EHT-2 and 4EHT). Equivalent outer diameter of the tube was 9.52 mm (0.375 in) and the inner diameter was 8.32 mm (0.3276 in).
