Welcome to Our Website,We Are Happy to Serve You
The UQD Series Liquid-Cooled Quick Coupling by Hoonsun is a high-performance, precision-engineered fluid connection solution designed for demanding liquid cooling applications. Built from premium 316L stainless steel with versatile sealing options (standard EPDM, optional HNBR/FKM), it delivers exceptional corrosion resistance, zero leakage, and reliable performance across a wide range of fluids and temperatures.
Engineered for efficiency, it supports a rated working pressure of 20 bar (burst pressure 80 bar) and operates reliably from -40°C to +120°C. With four sizes (DN03 to DN10) and multiple connection options (UNF/G threads, self-clinching hose barbs), it offers seamless integration into various liquid cooling systems, from small lab equipment to large-scale data centers and industrial setups.
Applications
• Data Center & HPC Liquid Cooling: Server rack and high-performance computing cooling systems
• EV Charging Piles & Thermal Management: Liquid cooling connections for electric vehicle charging infrastructure
• Industrial Laser Equipment: Precision cooling for high-power industrial lasers
• Medical Equipment: MRI machines, diagnostic devices, and precision instrument cooling
• Photovoltaic Inverters: Outdoor solar and wind power electronic cooling systems
• Test Benches & Automated Systems: Reliable fluid connections for laboratory and industrial test setups
• High-Density Electronic Systems: Compact, efficient connections in limited-access environments
Installation Process
1. Preparation: Ensure the coupling and mating components are clean, free of debris, and undamaged. Depressurize the fluid system before installation.
2. Connection: Align the plug and socket, then push straightly until a click sound confirms complete locking.
3. Verification: Perform a pressure test to confirm no leaks before bringing the system online.
4. Disconnection: Depressurize the system, then simply pull the plug out of the socket. The coupling will automatically seal to prevent fluid loss.
Safety Note: Never connect or disconnect the coupling while the system is under pressure. Protect the sealing surface from scratches to maintain leak-proof performance.
