Code Moment | Liquid Cooling Leader "Yixintong" Closes Series B+ Round, Raising Nearly RMB 200 Million Across Two Rounds

On May 19, 2026, MaHui member and Beijing E-Trust Technology Co., Ltd. (hereinafter "E-Trust"), a high-tech enterprise in the ICT liquid cooling sector, officially announced the completion of its Series B+ funding round, with exclusive strategic investment from CRRC Capital. Source Code Capital led E-Trust's Series A round.

Previously, the company completed its Series B round, led by a Fortune 500 global corporation with participation from multiple well-known institutions. The two rounds combined have raised nearly RMB 200 million.

The proceeds from this round will be directed toward four priorities: core product R&D, production capacity expansion, overseas market development, and team building — supporting E-Trust's next phase of growth in the data center and AI computing center liquid cooling track.

01

Full-Stack Liquid Cooling Positioning Ranks Among China's Top Liquid Cooling Players

Founded in 2021, E-Trust has, in just five years, become one of China's leading liquid cooling companies. The company integrates R&D and manufacturing, solution provision, and full-lifecycle liquid cooling services, while mastering both of the industry's mainstream technical approaches — cold plate liquid cooling and immersion liquid cooling. Its product portfolio covers CDUs (Coolant Distribution Units), Manifolds, TANKs (immersion cooling tanks), liquid cooling container data centers, and pre-fabricated piping across the full stack.

The company's client base spans nearly all the top-tier names in China's liquid cooling space — from leading internet and cloud service providers, to mainstream server OEMs, top IDC operators, and major telecom carriers. Overseas, its solutions have already been deployed in multiple national-level computing projects and multinational data center operations. To date, E-Trust has cumulatively delivered liquid cooling projects exceeding 1.5 GW in scale, with equipment having accumulated over 10 million hours of stable, failure-free operation.

Solid R&D Foundation Operates One of China's Largest 2.5MW Liquid Cooling Labs

E-Trust has maintained high R&D investment intensity over the long term. The company operates one of China's largest 2.5MW liquid cooling laboratories, complemented by a materials lab, reliability verification and testing center, and a 24,000-square-meter "E-Trust Precision" smart manufacturing facility. It holds over 50 core intellectual property assets and has participated in formulating four liquid cooling industry standards, contributing to benchmark documents such as the Technical Specification for Data Center Liquid Cooling Systems. The company is also certified under four international management systems — ISO 9001, ISO 14001, ISO 45001, and ISO 3834 — with core products obtaining UL and CE international certifications.

03

Global Expansion Targeting Overseas AI Computing Demand

As large-scale AI model training and intelligent computing center construction accelerate worldwide, overseas demand is surging for high-density, rapid-deployment, mobile liquid cooling data centers. E-Trust has established an overseas R&D and production base in Malaysia, with business and after-sales networks covering six regions: Southeast Asia, East Asia, the Middle East, Africa, Europe, and the Americas.

Xia Zhang, Founder and CEO of E-Trust, said: "For the past five years, we've been focused on one thing — making liquid cooling good enough, reliable enough, and global enough. The completion of these two funding rounds tells us we're on the right path. Our next priority is overseas: getting Chinese liquid cooling technology truly embedded in global intelligent computing infrastructure. Our mission hasn't changed: making computing power cooler, more efficient, and more accessible."
