High-and Low-Temperature Heat Transfer Fluids
UOLEN®40
-40°C to 250°C
Product Features
- Colorless transparent liquid
- Suitable for closed-loop system equipment
- Excellent thermal stability, maximum service temperature resistance up to 330°C (626°F)
- Freezing point below -50°C (-58°F), low kinematic viscosity at low temperatures, and good fluidity for low-temp. pump startup
- 3-5 times longer fluid life than that of mineral-based heat transfer fluid
Working Temperature Range
UOLEN®330 fluid has a temperature range of –15°C to 290°C (5°F to 554°F)
without overpressure or up to 330°C (626°F) with appropriate level of system pressurization.
