Description
Optimize your high-vacuum applications with DHVE 702 Diffusion Pump Oil, a premium-grade, silicone-based fluid engineered as a direct structural and functional equivalent to Dow Corning DC 702.
Designed specifically for rapid pumping of large volumes of gas, DHVE 702 offers exceptional chemical and thermal stability, resisting oxidation and performance degradation even under rigorous operating conditions. Whether you are running electronics manufacturing, vacuum metallurgy, or thin-film coating operations, DHVE 702 ensures stable ultimate pressures and extended service life for your high-vacuum diffusion pumps.
Key Features & Benefits:
- Direct DC 702 Drop-In Replacement: Seamlessly transitions into systems engineered for standard 702 silicone fluids without requiring equipment modification.
- Rapid Pump-Down Times: Maximizes throughput by facilitating fast, efficient gas evacuation.
- High Thermal & Chemical Stability: Minimizes sludge and carbon buildup, significantly reducing maintenance intervals and downtime.
- Low Vapor Pressure: Minimizes fluid backstreaming to maintain a clean, contaminant-free vacuum chamber environment.
Primary Applications:
- Aerospace and space simulation chambers
- Vacuum metallurgy and heat-treating furnaces
- Thin-film optical and decorative coatings
- Semi-conductor processing and electronics manufacturing
