Turbo Chill Tubes


Turbo Chill Tubes

Turbo Chill Tubes is an integral low fin tube provided with spiral ridges on the inside. In a Turbo Chill Tube, the inside fluid heat transfer capability is remarkably improved in comparison with the smooth in-tube type tubes. By the effects multiplied mutually by the tubes outside fins and inside spiral ridges a high coefficient for overall heat transfer is obtained. These parameters significantly contribute to the reduction in size of various freezing machines. Normally, Turbo Chill Tubes are generally supplied with 8 & 10 starts configuration; however, it can also be fabricated with other number of starts on request. These tubes are fabricated in alloy C 12200 to meet the chemical, mechanical and other test parameters of ASTM B 75 / B 359 and in alloy 70600 to meet the chemical, mechanical and other test parameters of ASTM B 111 / B 359. BS EN, JIS and DIN standards are also available on request.

  • For tube parameters of 22.2 mm, 25.4 mm tube or any other special requirements please contact us.
  • Turbo Chill tubes with fin density other than mentioned in the above chart can be produced on request.
  • Turbo Chill Tubes with alloy 71500 is also available; please contact us for Fin parameters.
  • Turbo Chill Tubes are generally supplied in the “as finned” condition. However, alloy 70600 & 71500 can be supplied in “annealed” temper upon specific request.
  • Turbo Chill Tubes are generally produced with desired plain ends, tubes can also be fabricated with intermediate landings upon specific request.
  • Turbo Chill Tubes are produced in straight length up to 8 Meters. Bigger lengths can be accommodated on request.
  • Turbo Chill Tubes are supplied with deburred / smooth ends.


End Applications : Refrigeration, Chemical, Petrochemical, LNG, Boiler Applications etc.
