Galden HT S is a wide-temperature perfluoropolyether (PFPE) heat transfer fluid within the Galden HT series. It offers a typical operating temperature range of -70 °C to 290 °C, with boiling points spanning from 55 °C to 270 °C. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid is specifically optimized for system-level thermal management in complex and demanding applications.
Unlike standard single-boiling-point HT grades, Galden HT S is engineered for wide-temperature thermal cycling and multi-system operation. Its highly stable C-F molecular structure delivers consistent thermal performance across large temperature fluctuations. This makes Galden HT S an ideal solution for high-reliability electronic systems, semiconductor equipment, and industrial recirculating temperature control applications.
