About Globaltherm® Omnisol
- Globaltherm® Omnisol – is a silicone based heat transfer media used in solar thermal storage applications at high temperatures.
- Omnisol can safely withstand temperatures up to 425°C (797°F).
- Globaltherm® Omnisol delivers the high thermal stability and reliable heat transfer of a polydimethylsiloxane mixture with a low pumpability point of -65°C (-85°F). Globaltherm ® Omnisol is a high performing low toxicity, low fire risk, heat transfer fluid for CSP applications operating up to 425°C (797°F).
- Globaltherm® Omnisol is suitable for use in parabolic trough applications requiring a low freeze point and low temperature pumpability.
