Ceramic Coated Hydraulic Actuator

High-temperature hydraulic cylinders are designed to operate reliably in extreme heat environments up to 600°C, utilizing innovative thermal management solutions. These rugged actuators feature a unique combination of active and passive cooling systems, including vortex tube air cooling and phase-change materials that absorb and dissipate heat more effectively than conventional designs. The cylinders employ specially formulated high-temperature hydraulic fluids with flash points above 300°C, preventing vapor lock and maintaining viscosity in thermal cycling conditions. Their multi-stage thermal protection system integrates ceramic thermal barriers, refractory metal components, and advanced cooling channels that maintain critical components below 150°C even when external temperatures exceed 500°C.   In aerospace applications, these cylinders operate in jet engine test stands, enduring extreme radiant heat while providing precise thrust vector control during engine testing.
