UOLEN85
Product Model UOLEN®85
Operating Temperature Range: -85°C to 230°C(-121°F to 446°F)
UOLEN®85 is a synthetic hydrocarbons designed for both heating and cooling applications. It exhibits excellent low-temperature fluidity, low circulation resistance, and high heat transfer efficiency. As an indirect heat transfer medium for temperature control systems, it is suitable to use in industries such as food freeze-drying, pharmaceutical manufacturing, and chemical industry. This fluid is engineered for closed-loop temperature control systems within the range of -85°C to 230°C (-121°F to 446°F), ensuring reliable performance in both heating and cooling processes.UOLEN85 is equivalent to Therminol D12 and they can be mixed in any proportion.
