Features
  • Through optimization of groove geometry, the inside heat transfer coefficient improved by 1.5-2 times in comparison to smooth tubes.
  • The pressure drop due to the use of FMGT increases only slightly compared to conventional smooth tubes, bringing about no problems of practical importance.
  • FMGT is available in either straight tubes or level-wound-coils, complying with the use of our customers.

Use
  • FMGT is mainly used as refrigerant heat transfer tubes of heat exchangers for such air conditioning equipment as room air conditioners and package air conditioners.
  • It is also used as heat pipes for heat radiation of various electronic equipment.
