Cryogenic exchangers

Graham Heliflow Heat Exchaner in cryogenic service

Graham has conducted extensive research and development in the area of cryogenic vaporizers. Our research and many years of proven experience in this area confirm that the Heliflow heat exchanger is excellent for cryogenic applications. The unique tube coil of the Heliflow can easily accommodate the large temperature differentials that are typical in cryogenic units.

Heliflows often use cryogenic fluids as the cooling medium; alternately, Heliflows can be used to vaporize fluids, such as N2, O2, CO2, or other fluids. For information on this subject, refer to the Graham article titled Convective Flow Boiling in Coiled Tubes.
