Keep your coolant on spec — continuously.
Inline refractive index measurement gives liquid-cooled AI and HPC halls a live view of coolant concentration.
Water–glycol concentration determines corrosion protection, biological stability, freeze protection and heat transfer capacity — and it is a parameter you can hold precisely. Continuous inline refractive index (RI) measurement turns concentration into a live, temperature-compensated signal in your BMS or DCIM, so the loop stays on spec between fills, top-ups and service.
What’s inside
- Why coolant concentration changes during service life, even in a closed loop
- What goes wrong when the mixture runs too dilute or too concentrated
- How inline refractive index measurement works, and why it does not drift
- Where to measure: TCS coolant line, CDU, fill and blending skid, and the facility water loop where relevant
- Vaisala Polaris PR53AC and PR53GP selection, mounting options, and user interface options
