Founded in 1992, "De Kuang Jiu Ding" is a national high tech enterprise that integrates R&D, manufacturing, and sales.

Headquartered in Beijing's Zhongguancun Science Park and with a 40, 000m2 manufacturing base in Zhongguancun Science City (Tianjin Baodi), the company is strategically positioned for innovation and scale.

As mining depths increase, underground hazards have expanded from the traditional five (water, fire, gas, coal dust, roof collapse) to seven - now including heat damage and rock bursts. De Kuang Jiu Ding specializes in complete solutions and equipment for mine heat control and gas drainage. With over 30 years of dedicated focus, we are on a clear path to becoming the "hidden champion" in these two critical niches.

Market leadership speaks for itself:

De Kuang Jiu Ding holds the No. 1 market share in China's mining explosion proof refrigeration equipment industry. Hundreds of our systems are successfully operating in coal mines, non ferrous metal mines, and hightemperature traffic tunnels. Our technical expertise has also contributed to shaping China's energy industry standards.

Game changing innovation in gas drainage:

Our intelligent gas drainage pump station technology filled a major gap in the Chinese market. It remains the only technology that enables intelligent, controllable, and precise gas extraction. In 2024, this breakthrough won the First Prize for Scientific and Technological Progress from the China Coal Industry Association.

Our mission - everything for miners' safety and health.

Driven by this commitment, we collaborate longterm with leading universities and research institutes at home and abroad. Through joint R&D and active technical exchanges with major mining groups worldwide, we help coal and noncoal mines solve the toughest safety and production challenges.
