Bringing Industry-Recognized Standards to Liquid Cooling Applications
QINFENG Technology has extended its existing 3A and TUV certifications to cover the full range of liquid cooling components supplied to data center operators and CDU manufacturers. The expanded certifications provide documented quality assurance for customers who require traceability and regulatory compliance across international projects.
Certified Product Lines Now Include Key Liquid Cooling Components
The newly certified product portfolio includes:
3A-certified pipe fittings and ball valves: These sanitary-grade certifications confirm that components meet the surface finish, material traceability and cleanability standards required for high-purity fluid systems — an attribute that also benefits liquid cooling loops where coolant purity directly affects system performance and heat exchanger life.
TUV-certified austenitic stainless steel butt-weld pipe fittings and formed parts: TUV certification provides third-party verification of dimensional accuracy, material chemistry and pressure-holding capacity, giving engineering teams confidence when integrating Qinfeng components into facility-wide liquid cooling architectures.
Special Equipment Manufacturing License: Issued under Chinese regulatory framework, this license documents Qinfeng’s qualifications to manufacture pressure-containing components for critical infrastructure applications.
Why Certifications Matter for Liquid Cooling Projects
For hyperscale data center operators, colocation providers and CDU manufacturers, component certifications serve two practical purposes. First, they simplify procurement by reducing the need for duplicate quality audits. Second, they provide regulatory documentation required in jurisdictions where third-party approvals are mandatory for mechanical components in occupied facilities. Many of Qinfeng’s customers in North America and Europe specifically request 3A and TUV certifications during vendor qualification. Bringing liquid cooling components under these existing certifications means faster onboarding for new projects and smoother supply chain compliance.
