The heat transfer properties of different cooling systems dealing with Poly-Ethylene-Terephthalate (PET) bottles were investigated. The heat transfer coefficient (U<inf>g</inf>) was measured in various fluid dynamic conditions. Cooling media were either air or water. It was shown that heat transfer coefficients are strongly affected by fluid dynamics conditions, and range from 10 W/m<sup>2</sup> K to nearly 400 W/m<sup>2</sup> K. PET bottle thickness effect on U<inf>g</inf> was shown to become relevant under faster fluid dynamics regimes.
