International Recognition | Letone Technology's Liquid Cooling Tubing Receives UL Certification

Recently, the LT800 series liquid cooling pipeline products for data centers, independently developed by Letone Technology, have successfully passed the authoritative certification issued by Underwriters Laboratories (UL) in the United States and obtained the UL certification certificate.

As a globally recognized authoritative institution for safety and compliance in the data center industry, UL certification is a mandatory qualification for bidding in the overseas high-end computing infrastructure market. The certification covers dozens of stringent tests including material flame retardancy, temperature and pressure resistance, chemical corrosion resistance, aging resistance and mechanical reliability, setting extremely high standards for the safety, stability and compliance of products throughout their life cycle.
Relying on solid technical strength, the LT800 series liquid cooling pipeline products of Letone Technology have achieved UL94 V0 grade in core flame retardant performance. The after-flame burning time is less than 5 seconds with no burning drips generated after leaving the fire source.

The LT800 series liquid cooling pipeline products that have obtained UL certification this time are targeted solutions developed by Letone Technology to address the heat dissipation pain points of AI supercomputing centers and high-density cloud computing data centers.

Leveraging the company’s profound accumulation in the field of ultra-high pressure fluid technology over more than two decades, this product series has achieved multiple technological breakthroughs. It features an operating temperature range from -40℃ to +120℃, and is fully compatible with mainstream cooling media such as water and water-glycol solutions, delivering outstanding chemical corrosion resistance and permeation resistance. With a minimum bending radius of only 21.6 mm, the products perfectly meet the flexible wiring requirements of narrow spaces in computer rooms. Matched with UQD dry quick couplings that comply with OCP open standards, they enable drip-free plugging and one-handed quick connection within seconds, greatly reducing the deployment difficulty and operation and maintenance costs of liquid cooling systems in data centers.

Fully compatible with mainstream liquid cooling solutions across the industry, this product series effectively meets the heat dissipation demands of ultra-high power computing equipment, and closely aligns with the national initiative for green data center construction and the dual-carbon goals.

The successful acquisition of UL certification marks that Letone Technology’s liquid cooling products have officially obtained access qualifications to high-end global data center markets such as North America and Europe, serving as a key milestone in the company’s layout in the data center liquid cooling track.

This achievement not only demonstrates Letone Technology’s strong R&D strength in the fluid technology sector, but also lays a solid foundation for the global expansion of its liquid cooling business and the domestic substitution of core components for high-end computing infrastructure.

As a specialized, sophisticated, distinctive and innovative "Little Giant" enterprise and the "first rubber hose stock" listed on the Beijing Stock Exchange, Letone Technology has always adhered to the development strategy of "Original Innovation for Leadership, Altruism for Co-creation", and taken R&D and innovation as the core lifeline of corporate development.

Following the completion of this UL certification, Letone Technology will continue to increase investment in liquid cooling technology research and product iteration. Anchored by international authoritative standards, the company will continuously optimize comprehensive solutions for liquid cooling pipeline systems. Empowering the computing power revolution in the AI era through technological innovation, it will provide safer, more efficient and more reliable domestic fluid technology solutions for the construction of global green computing infrastructure, and steadily advance the domestic substitution and global development of China’s high-end fluid equipment manufacturing industry.
