Galden HT200 200 °C Balanced Performance PFPE Heat Transfer Fluid

Galden HT200 is a high‑performance perfluoropolyether (PFPE) heat transfer fluid within the Galden HT series. It delivers the lowest viscosity at 2.40 cSt and the lowest pour point of -85℃ across all HT grades with boiling points above 170℃. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid has a boiling point of 200℃. It strikes a good balance of heat transfer efficiency, low‑temperature fluidity and high‑temperature stability for challenging thermal management tasks.

Galden HT200 shows far superior flow performance and quicker thermal response when compared with higher‑viscosity Galden HT230 (4.40 cSt) and Galden HT270 (14.0 cSt). Its boiling point runs 30℃ higher than Galden HT170 (170℃). An ultra‑low -85℃ pour point grants excellent pumpability under cold conditions. This makes Galden HT200 the most flexible option in the HT series. It suits systems that demand effective high‑temperature heat transfer as well as dependable cold‑start operation.
