Non-drip screw coupling for data center CDU

Non-drip screw coupling for data center CDU

For connecting the cooling water circulation system of the data center! OCP standard threaded non-drip coupling.

The Large Quick Connector (LQC) for data centers was developed for cooling water circulation devices (CDU) within the Open Compute Project (OCP) initiative. We are one of the manufacturers that developed this standard. The screw connect method of the OCP LQC is more user-friendly than the push-to-connect type quick connect couplers and can be connected even under a maximum operating pressure of 0.5 MPa. Because it is an open standard, any manufacturer's product can be connected as long as it adheres to the LQC standard specifications. Our LQC couplings comply with the standard and exceed its specifications.

Data center liquid cooling blind mate quick coupling

Data center liquid cooling blind mate quick coupling

For rack-mounted servers in data centers! OCP standard blind mate coupling.

The Universal Blind Mate Quick Connector (BMQC) for data center applications was developed within the Open Compute Project (OCP) initiative. We are one of the manufacturers that developed this global standard specification. With features such as drip-free attachment and detachment, a compact design, blind mate functionality, an astonishing axial and perpendicular core misalignment tolerance of ±5mm, and an inclination angle tolerance of ±2.7°, it is ideal for direct liquid cooling (DLC) applications in the data center field.

Smart Flow Drive Lake Coupling

Smart Flow Drive Lake Coupling

TEAM SPEC / Compliant with STANAG 3756, no liquid leakage. Coupling for liquid transfer.

Smart Flow Drive Lake Couplings are designed to support safe, efficient, and environmentally friendly fluid transfer in harsh environments where safety is a priority. With minimal components and no need for additional valves, they allow for leak-free connections and disconnections, saving both time and costs. They are commonly used in AdBlue distribution, road and rail tankers, offshore applications, marine bunkering, and IBC filling. Smart Flow Couplings feature a safety factor of five times the operating pressure of 2.5 MPa, regardless of size or material. This is unique in the industry, and for applications requiring higher pressures, you can choose Smart Flow aluminum units as a lighter and more cost-effective alternative to competitors' stainless steel units. Compliance with TEAM SPEC and STANAG 3756 standards ensures compatibility with products from other manufacturers. Additionally, FDA-approved O-rings are available to meet the stringent safety and hygiene standards required for use in food and beverage manufacturing.

Blind Mate Auto Coupling

Blind Mate Auto Coupling

Minimal air intrusion and leak-free attachment and detachment. Compact auto-coupling suitable for integration into server racks.

Designed for thermal management applications that require minimal air ingress and leak-free attachment and detachment. The unique design prevents damage to seals during attachment and detachment under pressure, ensuring a highly airtight fit. Automatic alignment features enable blind connections. Made from durable and corrosion-resistant stainless steel and hardened anodized aluminum alloy. The temperature range for the specially developed nitrile (NBR) seals in this series is -40°C to 80°C. EPDM seals are also available.

Quick Connect Coupling for Data Centers

Quick Connect Coupling for Data Centers

High-performance coupling for data centers requiring advanced and powerful thermal management systems.

Sain collaborates with leading companies in the data center industry, manifold manufacturers, and chassis manufacturers to design and develop compatible quick connect solutions, contributing to the OCP (Open Compute Project) community. They manufacture products compliant with OCP specifications such as UQD, UQDB, LQC (OCP Large), and BMQC (OCP Blind-mate). Due to their use in delicate environments and limited spaces, there is a need for compact quick connectors that maintain the best performance and the lowest pressure loss. Sain offers a variety of couplings for data centers that feature no liquid leakage, low pressure loss, and high flow rates.

Safe and high-performance quick connect couplings for hydraulic, pneumatic, and fluid applications.

Safe and high-performance quick connect couplings for hydraulic, pneumatic, and fluid applications.

Please consult with us regarding issues such as liquid dripping during disconnection, misconnection of pipes, and hose flailing. Improve the efficiency and safety of your workspace with high-performance couplers!

Since its first patented coupling was launched in 1955, Sain has been manufacturing safe and high-quality products for over 60 years. It has established itself as a standard manufacturer in the European market and currently sells in 17 locations worldwide. ■ How Sain products can contribute to solving customer challenges ■ 1. Optimize energy efficiency - contributing to energy savings High-quality couplings and air guns with excellent flow characteristics and designs that minimize pressure loss reduce unnecessary costs. 2. Safe connection and disconnection - contributing to workplace safety Air couplings with residual pressure removal mechanisms, slow-retracting hose reels, and misconnection prevention couplings eliminate accidents. 3. Drip-free product design - reducing environmental pollution For chillers, drip-free liquid cooling couplings prevent the leakage of refrigerants with high global warming potential. Choosing hydraulic couplings that do not leak oil for construction machinery can reduce environmental impact. 4. High durability, repairability, and ease of maintenance - reducing running costs We pursue coupling structures that are easy to maintain. A wide range of hoses and spare parts is also available.
