Rooted in Chinese Academy of Sciences, Engineering Clean Energy for the Future

ZhongKe JiuLang inherits nearly 70 years of energy research heritage from the Institute of Engineering Thermophysics, CAS — turning world-class science into industrial reality.

WHO WE ARE

A Pioneer in Pressure Energy Recovery Technology

Joulong Energy Technology Co., Ltd., originating from the Chinese Academy of Sciences, specializes in natural gas pressure-differential power generation and cold energy recovery.

We develop, design, and manufacture turnkey systems — converting wasted pipeline pressure into clean electricity and usable cooling.

Our turbine expander technology delivers ≥85% efficiency at up to 40,000 rpm, supported by 27 patents.

RENEWABLE ENERGY

Pressure is Energy

WHAT DRIVES US

Our Values

Rooted in the innovative, rigorous, and focused ethos of its academic heritage, Jiulang fosters a corporate culture of diligence, pragmatism, and openness. We bring together top industry talent, commit to staying at the forefront of technology, and uphold a client-first philosophy. Through continuous innovation in our core technologies and business development models, we are determined to become a first-tier energy technology and service enterprise in China.

Rigour

Grounded in decades of research at the Chinese Academy of Sciences, we approach every project with scientific rigour — from feasibility analysis and system design to manufacturing and on-site commissioning. Every parameter is verified. Every component is tested.

Innovation

Our proprietary radial turbo-expander technology delivers industry-leading efficiency at 40,000 rpm. Backed by 27 patents, we continuously push the boundaries of what pressure energy recovery can achieve — developing new coupling solutions for ice production, data centre cooling, and EV charging infrastructure.

Trust

We believe trust is earned through results. Every system we deliver is customised to the client's exact pipeline conditions, backed by a 25-year design life, full bypass redundancy, and long-term technical support. Our first grid-connected unit has been operating reliably since 2021.

Research Heritage

Backed by the Institute of Engineering Thermophysics, CAS

The Institute of Engineering Thermophysics (IET), Chinese Academy of Sciences was established in 1956. For nearly 70 years, it has focused on major national strategic needs, tackling critical scientific challenges in engineering thermophysics, and advancing applied research, key technology development, and system integration in energy and power.

The institute has been awarded 100+ national and provincial-level prizes, cultivated numerous academicians, and pioneered foundational theories including the “Three-Dimensional Flow Theory in Turbomachinery” and the “Temperature-Matching, Cascade Utilization” principle — forming the scientific bedrock of modern energy systems.
