## About

Shenzhen Longtech Smart Control was established in 2003 by Ouyang Zhengliang, who remains Chairman and Legal Representative. The firm entered the Shenzhen Stock Exchange in 2021 under ticker 300916, with institutional shareholders Shenzhen Pengcheng Gaofei Investment Management Partnership (≈8.8%) and Zhuhai Pengcheng Zhanchi Investment Consulting Partnership (≈3.06%) on the register. Its wealth origin is corporate industrial profit rather than a single-family fortune, and Longtech operates four self-owned industrial parks across Shenzhen, Dongguan, and Jiangxi Province. The firm’s investment posture spans three concrete businesses. Energy storage systems form the headline — Longtech describes itself as a lithium ESS integrator shipping to more than 100 countries, with disclosed annual production capacity of 2.5 GWh. In automotive electronics, Longtech has held IATF 16949 certification since 2013 and maintains a complete R&D stack from hardware to EMC validation. The third vertical, added more recently, is liquid-cooled computing infrastructure: the firm advertises rack-level systems for AI training clusters at >7,500 kW total power with a PUE of 1.05–1.15, alongside edge-scale 8–16 GPU immersion-cooled units. Longtech’s website claims a 150-person technical team, 84 patents, and six standard laboratories. Working capital moves across four industrial sites: Building G of Jianshi Industrial Park and the Zhengfeng Industrial Park in Shenzhen, a Dongguan Langqin site, and the Jiangxi Longtech Industrial Park. The firm also runs an internal Love Mutual Aid Fund, a low-profile employee-directed social vehicle. Structurally, Longtech is a listed Chinese operating company deploying its own balance sheet, not an external asset manager. That makes it a direct manufacturing investor — it builds production lines, not LP commitments.

## Questions

### Who controls investment and strategic direction at Shenzhen Longtech Smart Control?

Founder Ouyang Zhengliang serves as Chairman, Legal Representative, and Actual Controller of the firm. Furong Fang acts as General Manager and Director. Two institutional co-investors — Shenzhen Pengcheng Gaofei Investment Management Partnership (≈8.8%) and Zhuhai Pengcheng Zhanchi Investment Consulting Partnership (≈3.06%) — hold minority stakes, but Ouyang Zhengliang retains ultimate control per the firm’s own disclosures.

### What role does liquid cooling play in Longtech’s current business?

Longtech has added liquid-cooled computing hardware as a distinct product line, spanning large-scale AI training clusters, smaller 2,500–7,500 kW data-center modules with PUE as low as 1.05, 8–16 GPU immersion-cooled edge units, and personal GPU workstations. The firm explicitly targets AI training, green data centers, industrial IoT, and low-altitude-economy applications, repurposing its existing thermal-management expertise.

### What physical assets does Longtech own?

According to Altss research, Longtech controls four industrial parks: Jianshi Industrial Park (Building G) and Zhengfeng Industrial Park in Shenzhen, a site in Dongkeng Town, Dongguan, and the Jiangxi Longtech Industrial Park in Anfu County, Ji’an City.
