Description
Technical Parameters
What is the Universal Quick Disconnect (UQD)?
The Universal Quick Disconnect (UQD) is an advanced thermal management solution specifically designed to enhance liquid cooling systems in data centers and support high-performance computing (HPC) needs. Offered by Pride, UQDs are engineered to meet the rigorous standards of the Open Compute Project (OCP) and deliver exceptional performance in demanding environments.
Available in four sizes and two distinct color options (red and blue for easy identification), the UQD simplifies maintenance and operation with a push-to-connect design and flat-face double shut-off valves, ensuring high flow without spillage. By exceeding OCP flow ratings by at least 25%, the UQD reduces energy consumption and improves the efficiency of liquid cooling loops, which are critical for managing the heat generated by HPC and high-performance servers. Additionally, its 100% helium-leak testing guarantees leak-proof operation, minimizing the risk of downtime and protecting sensitive equipment. These features make UQDs an indispensable choice for sustainable and reliable thermal management in modern data centers.
Universal Quick Disconnect (UQD) Product Specifications
The Universal Quick Disconnect (UQD) is meticulously designed to deliver exceptional performance and versatility in liquid cooling applications. Constructed from durable 303 stainless steel, it offers broad fluid compatibility, making it suitable for various high-performance computing (HPC) and data center cooling needs. The standard seal material is EPDM, ensuring reliable operation across a wide range of conditions, while color-anodized aluminum sleeves and color-coded (red/blue) markings on sockets and O-rings on plugs provide easy identification and assembly.
The UQD supports a wide range of terminal end options, including ORB, BSPP on plugs, and push-on hose fittings on sockets, with additional configurations available upon request. It is built to withstand operating temperatures from -40°C to +150°C and features a typical working pressure of 6.9 bar, accommodating up to 20 bar for smaller sizes. These specifications highlight the UQD's robust design and adaptability, making it an ideal choice for demanding thermal management systems.
