EPDM Liquid Cooling Hose
Product Overview
TONMAX EPDM liquid cooling hose is a multi-layer composite rubber hose made of ethylene propylene diene monomer (EPDM) as base material. It is specially designed for liquid cooling thermal management systems and compatible with common coolants such as water-glycol and propylene glycol. This cooling hose delivers wide temperature stability, superior flexibility, outstanding chemical compatibility and weather resistance. It has passed pulse fatigue, burst pressure, flame retardant and other strict tests. Widely deployed in data center liquid cooling, high-power superchargers, new energy energy storage, industrial machinery, communication base stations and scientific research platforms, offering stable, cost-effective pipeline solutions for complex working conditions.
Main Applications
• Data center liquid cooling: cold plate liquid cooling pipeline, external circulation pipeline for immersion cooling, main supply & return water pipeline for computer room
• High-power charging facilities: internal cooling pipeline for charging cables of DC superchargers
• New energy & energy storage systems: liquid cooling circuit for battery packs and thermal management pipelines of energy storage cabinets
• Industrial machinery: cooling circulation pipelines for lasers, CNC machine tools and injection molding equipment
• Outdoor communication base stations & special equipment, laboratory fluid transmission and environmental simulation test equipment
Core Advantages
