Fire‑resistant hydraulic oil 46EHC

Product description
Fire‑resistant hydraulic oil 46EHC is also called Fire-resistant fluid 46EHC,
EH control system oil is the most‑widely‑adopted fluid for steam turbines  thermal power plants. Compared with ordinary hydraulic oil, it features non‑flame‑propagation performance, high auto‑ignition point, low corrosivity, high resistivity, good anti‑foam property, as well as excellent hydrolytic and oxidative stability. It has been extensively used in major thermal power generating units across China.
