FRAGOLTHERM® Q-7 is a catalytically hydroisomerized mineral oil produced through a special process, with a high content of isoparaffinic hydrocarbons and an extremely low content of sulfur, nitrogen, and aromatic compounds. The base oil undergoes special hydrocracking, solvent deparaffinization, and hydroprocessing, as well as subsequent distillation, to produce a high-quality, transparent, and virtually odorless heat transfer fluid.
