FRAGOLTHERM® Q-7

Heat transfer fluid from -48°C to 270°C

FRAGOLTHERM® Q-7 is a heat transfer fluid based on hydrogenated mineral oils that is used in a range of -48°C to 270°C. The maximum permissible film temperature is 340°C.

Application Area

Application

FRAGOLTHERM® Q-7 has been specially developed for heating and cooling systems. Despite good thermal stability and a low tendency to oxidise, it is advisable to utilize a nitrogen blanket in the expansion tank during use in high temperature ranges, in order to prevent premature ageing.

FRAGOLTHERM® Q-7 is a catalytically hydroisomerized mineral oil produced in a special process, with a high proportion of isoparaffinic hydrocarbons and an extremely low proportion of sulphur, nitrogen and aromatic compounds. The base oil is subject to special hydro-cracking, solvent de-waxing and hydro-finishing processes, as well as subsequent distillation in order to produce a high performance, transparent and almost odourless heat transfer fluid.
