LCH Fire Resistant Rubber Hose for Data Center Liquid Cooling Systems
Reliable Fluid Transfer Solution for Next-Generation Data Centers
As artificial intelligence (AI), high-performance computing (HPC), and cloud computing continue to drive higher server power density, traditional air cooling solutions are becoming increasingly challenging to maintain efficiency. Liquid cooling systems are emerging as a critical technology for modern data centers due to their superior heat dissipation capability, energy efficiency, and compact installation advantages.
In liquid cooling applications, the hose assembly plays a vital role in maintaining stable coolant circulation. A reliable liquid cooling hose must provide excellent chemical compatibility, low permeability, pressure resistance, fire safety, and long-term operational reliability.
CJan Fluid Technology Co., Ltd. developed the LCH Series Fire Resistant Rubber Hose specifically for data center liquid cooling applications. Designed with high-purity EPDM rubber and a reinforced multi-layer structure, the hose delivers outstanding performance for coolant transportation in demanding environments such as AI data centers, server cooling systems, and high-performance computing facilities.
Why Data Centers Require Specialized Liquid Cooling Hoses?
Modern data center cooling systems often operate continuously under high thermal loads. The cooling hose must handle different types of coolant media while maintaining system reliability over long operating periods.
Common cooling fluids include:
Deionized water
Ethylene glycol solutions
Propylene glycol solutions
Fluorinated cooling liquids
Compared with conventional rubber hoses, liquid cooling hoses designed for data centers require improved material stability and lower permeability to minimize coolant loss and maintain system efficiency.
The LCH Series uses specially formulated EPDM rubber materials to provide excellent resistance against common cooling fluids while reducing the risk of leakage, contamination, and performance degradation.
Key Advantages of LCH Data Center Liquid Cooling Hose
1. High Purity EPDM Material for Stable Coolant Compatibility
The inner tube of the LCH hose is manufactured from high-purity black antistatic EPDM synthetic rubber.
This material provides:
Excellent chemical resistance
Low extractables and reduced contamination risk
Long-term stability with various coolant fluids
Reliable performance in continuous circulation systems
The high-purity structure helps maintain coolant quality and supports stable operation of precision cooling equipment.
2. Improved Airtight Performance to Reduce Coolant Loss
Coolant loss caused by hose permeability can affect system efficiency and increase maintenance requirements.
Through optimized rubber formulation and manufacturing processes, the LCH Series provides enhanced airtight performance compared with standard rubber hoses.
This helps:
Reduce coolant evaporation and permeation
Improve cooling system efficiency
Extend maintenance intervals
Support long-term data center operation
3. UL94-V0 Fire Resistant Design for Enhanced Safety
Safety is a critical requirement in modern data centers where equipment value and operational continuity are extremely important.
The outer layer of the LCH hose uses aging-resistant EPDM rubber with UL94-V0 flame retardant performance.
Benefits include:
Improved fire safety protection
Reduced combustion risk
Enhanced reliability in critical infrastructure environments
4. Flexible Design for Space-Constrained Installations
Data center server racks often have limited installation space and complex piping layouts.
The LCH hose features:
Excellent flexibility

How to Select the Right Liquid Cooling Hose for Data Centers?
Choosing the correct hose is essential for maintaining liquid cooling system performance.
1. Check Coolant Compatibility
The hose material must be compatible with the cooling medium. EPDM is widely used for water-based coolant systems due to its excellent resistance to glycol solutions.
2. Consider Permeability and Leakage Control
Low permeability is important for reducing coolant loss and maintaining stable cooling performance.
3. Evaluate Installation Conditions
Flexible hoses with a small bending radius are ideal for compact server rack environments where space is limited.
4. Confirm Safety Requirements
For critical infrastructure such as data centers, flame resistance and material reliability should always be considered.
