Cavity Seals
Preferred Engineering developed the compressive rubber type cavity seal in 1988. We were the first to develop the Seal System that requires no compressed air to maintain the seal. In addition to increased sealing effectiveness, the Seal System offers a reusable seal, reduced installation time and dose, and reduced radwaste costs.
Features
- Proven Design: In Service At More Than 15 Units
- Passive Sealing: Requires No Air Lines
- Sectional Design: The Seal System Is Divided Into Several Sections To Permit Easy Handling
- Inherently Safe: Once Locked In Place, The Seal Cannot Be Dislodged
- Damage Resistant / Rugged Construction: Seal Cover Plates Provide Additional Protection To The Seal Reducing The Potential For Damage
Benefits
- Long Life Seal: Reusable For A Minimum Of 3 Outages
- Reduced Contamination: The Cover Plates And Toggle Bolts are Electro-polished To Facilitate Decontamination
- Simplified Installation: A Complete Installation Can Be Made In Less Than 1 Hour
