UOLEN320
Product Model UOLEN®320
Operating Temperature Range: 0°C to 320°C (32°F to 608°F)
UOLEN®320 is a synthetic hydrocarbon mixture heat transfer fluid, an economical model LQC320. It exhibits excellent thermal stability, high heat transfer efficiency, and superior thermal performance compared to mineral-based heat transfer oils. As a thermal fluid, it is ideally suited for closed-loop systems to operate between 0°C(32°F) and 320°C(608°F), enabling rapid heating and cooling cycles
