Product Overview
The DN80 Peroxide-Cured EPDM Twin Sphere Compensator is a mission-critical flexible joint specifically engineered for Data Center Liquid Cooling (DLC) and thermal management systems. Unlike standard EPDM, the peroxide-curing process significantly enhances thermal stability and resistance to compression set, ensuring a leak-free service life exceeding 15 years in constant-temperature cooling loops.
Featuring a twin-sphere (double-sphere) geometry for superior vibration isolation and an external center reinforcing ring to prevent bellows deformation under pressure surges, this joint is the gold standard for protecting sensitive server infrastructure. Equipped with SS304 stainless steel flanges, it ensures absolute system cleanliness and corrosion resistance.
Key Features
- Peroxide-Cured EPDM: Offers superior heat resistance and lower extractables compared to sulfur-cured EPDM, maintaining coolant purity and preventing rubber hardening over decades.
- Twin-Sphere High Damping: Double-sphere design provides maximum vibration absorption from high-efficiency pumps, protecting fragile liquid cooling manifolds.
- External Reinforcing Ring: An integrated center ring prevents “ballooning” and maintains structural integrity during pressure fluctuations or high-pressure testing.
- Marine-Grade SS304 Flanges: Precision-drilled to ANSI 150LB standards, providing a robust and rust-free connection for high-density cooling networks.
- Multi-Axial Compensation: Provides large allowable movements in axial, lateral, and angular directions to accommodate thermal expansion in long piping runs.
Applications
- Data Center Cooling Distribution Units (CDU): Primary flexible connection for coolant supply and return headers.
- Immersion Cooling Systems: Vibration isolation for circulating pumps in dielectric fluid loops.
- Rear Door Heat Exchangers (RDHx): Providing flexible links for rack-level cooling connections.
- Server Room Chilled Water Loops: Ensuring silent and reliable operation in high-density computing environments.
Frequently Asked Questions (FAQ)
Q: Why is “Peroxide-Cured EPDM” mandatory for data center liquid cooling applications instead of standard EPDM?
A: Data center cooling systems require extreme reliability and coolant purity. Peroxide-cured EPDM is superior because:
- Longevity: It has much better resistance to heat aging and oxidation, preventing the rubber from becoming brittle over 10-20 years of continuous service.
- Cleanliness: It releases significantly fewer “extractables” (impurities) into the coolant compared to sulfur-cured rubber, which is vital for protecting precision micro-channels in cold plates.
- Stability: It offers a lower “compression set,” meaning the seal between the rubber and the SS304 flange remains tight and leak-proof even after years of constant mechanical stress.
