Product Model UOLEN®45
Operating Temperature Range: -40°C to 300°C (-40°F to 572°F)
UOLEN®45 is an organosilicon-based synthetic thermal carrier. It exhibits exceptional high-temperature stability, low viscosity at low temperatures, high flash point, high fire point, high smoke point, strong oxidation resistance, and odorless properties. This fluid is suitable for semi-open constant-temperature systems operated at low temperatures. As a high-performance heat transfer medium, it is designed for closed-loop temperature control systems within the range of -45°C to 300°C (-49°F to 572°F), enabling rapid heating and cooling cycles with efficient thermal exchange performance.
