LCH-SD Fire Resistant EPDM Hose for Data Center Liquid Cooling Systems

Reliable Coolant Transfer Solution for AI Data Centers, HPC and Semiconductor Applications

The rapid development of artificial intelligence (AI), high-performance computing (HPC), and cloud infrastructure is driving higher power density in modern data centers. As traditional air cooling systems approach their limits, liquid cooling has become an increasingly important solution for efficient thermal management.

A reliable liquid cooling system requires more than efficient heat transfer. Every component in the cooling loop, including hoses, must provide long-term stability, chemical compatibility, low permeability, and safe operation.

The LCH-SD fire resistant rubber hose is specifically developed for data center liquid cooling and semiconductor cooling applications, offering excellent flexibility, high-purity EPDM performance, fire resistance, and reliable coolant transportation.

Why Are Specialized Hoses Required for Data Center Liquid Cooling?

Liquid cooling systems operate continuously under demanding conditions, where coolant purity, pressure stability, and material compatibility are critical.

Conventional rubber hoses may experience issues such as coolant permeation, material aging, contamination, or reduced performance after long-term operation.

For modern liquid cooling infrastructure, engineers typically require hoses with:

• Excellent coolant compatibility
• Low permeability and high gas tightness
• Fire-resistant properties
• Flexible installation capability
• Stable performance under continuous operation

LCH-SD is designed to meet these requirements by combining peroxide-cured EPDM rubber technology with reinforced construction for demanding cooling environments.

Main Features of LCH-SD Liquid Cooling Hose

1. High-Purity Peroxide-Cured EPDM Inner Tube

The inner layer of LCH-SD is manufactured from black smooth anti-static peroxide-cured high-purity EPDM synthetic rubber.

EPDM is widely recognized for its excellent resistance to water-based cooling fluids and environmental aging.

The high-purity inner tube helps reduce:

• Coolant contamination
• Material extraction
• Fluid discoloration
• Particle generation

The smooth inner surface also supports stable coolant flow and improves system cleanliness.

2. UL94-V0 Fire Resistant Design for Enhanced Safety

Fire safety is a key consideration in modern data centers and semiconductor facilities.

LCH-SD features a high-purity fire-resistant peroxide-cured EPDM outer cover with UL94-V0 flame resistance performance.

This fire-resistant structure helps improve safety in critical applications such as:

• AI data centers
• Cloud computing facilities
• Semiconductor manufacturing equipment
• High-performance computing systems

3. Improved Gas Tightness to Minimize Coolant Loss

Coolant leakage and permeation can increase maintenance requirements and operating costs in liquid cooling systems.

LCH-SD provides improved gas tightness compared with standard rubber hoses, helping reduce coolant loss during long-term operation.

Benefits include:

• More stable coolant circulation
• Reduced maintenance frequency
• Improved system reliability
• Longer service life

4. Spiral Wire Reinforcement for Flexible Installation

Modern data centers often require complex hose routing inside limited spaces.

LCH-SD uses an embedded spiral steel wire reinforcement structure combined with polyester fiber or customized aramid reinforcement.

This construction provides:

• Higher pressure resistance
• Better bending performance
• Improved mechanical strength
• Flexible installation in compact spaces

The hose can be easily routed around server racks, cooling modules, and equipment connections.
