Galden Solvay Solexis offers a safe Heat Transfer (HT) media
for demanding applications, including:
Semiconductor
Chemical
Pharmaceutical
Vapor Phase Heating
Transformer and Super Computer Cooling
Recirculating Chillers
Galden HT is a line of fluids with boiling points ranging
from 55°C to 270°C and pour points from 115°C
to 66°C. Galden HT fluids therefore cover a wider liquid
range than other fluorinated heat transfer fluids, with
typical use range temperatures exceeding 300°C.
