Radial Seal
The Radial Seal is a core sealing component for rotary air preheater rotors. Installed on the outer edge of the rotor’s radial partition plates, it directly controls the effectiveness of the main leakage path. The seal is a high-rigidity full plate, precisely placed along the rotor’s radius, and rigidly connected to the partition plates. Precision leveling ensures a flat, stable sealing surface.

Key Advantages
1. Main Seal for the Radial Leakage Path
The Radial Seal is a core sealing component for rotary air preheater rotors. Installed on the outer edge of the rotor's radial partition plates, it directly controls the effectiveness of the main leakage path. The seal is a high-rigidity full plate, precisely placed along the rotor's radius, and rigidly connected to the partition plates. Precision leveling ensures a flat, stable sealing surface.
2. High-Temperature Stability
The preheater's hot end can reach up to 480°C. Ordinary plates may warp or vibrate under such conditions. Our materials, including 16MnCr and 321 stainless steel, maintain shape and stability even at high temperatures. The design radial gap of 0.7–2.5 mm remains consistent during long-term operation. An optional elastic compensation structure makes the seal adaptive to thermal expansion.
3. Custom Fit and Full Installation Service
Each Radial Seal plate is customized according to rotor height, with lengths from 600 mm to 3000 mm. Precision laser cutting and leveling ensure a perfect fit. We provide one-stop service from design to installation and commissioning.
