FRAGOLTHERM® Q-7 is a catalytically hydroisomerized mineral oil produced via 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 hydrorefinement processes, as well as subsequent distillation, to produce a high-quality, transparent, and virtually odorless heat carrier liquid.
