The origins of Longking date back to the 1970s. At that time, the company operated in a completely different field—manufacturing electronic components and specialized equipment.
The 1980s became a turning point for Longking. The company began developing air-purification systems, dust separators, and environmental control devices. This was an uncommon direction for Chinese industry at the time, but if Longking excelled at anything, it was the ability to read the future early.

In the 2000s, Longking entered what could be called its “Golden Age of Innovation.”

During these years, the company created and introduced technologies that later became industry standards:

• Next-generation air purification systems

• High-efficiency electrostatic precipitators

• Energy-efficient control devices

• Low-emission technologies

Longking’s systems were installed in major energy and metallurgical plants. This earned the company the status of a “Famous Chinese Brand” and positioned it as a leading manufacturer across Southeast Asia.

Starting in the 2010s, Longking realized that environmental challenges extended far beyond air quality. This marked the beginning of a new strategy—the expansion into the full cycle of environmental industries.

The brand added new business segments:

• Water purification systems

• Treatment of solid and hazardous waste

• Ecological restoration projects (land, soil, green zones)

• Energy-storage and renewable-energy technologies

• Infrastructure for the comprehensive management of chemical and municipal waste

These changes transformed Longking from a single-industry supplier into a multi-disciplinary environmental powerhouse.

Today, Longking is considered one of the largest environmental groups in China and a strong global player. The company carries out:

• Multi-billion-dollar infrastructure projects

• Work aligned with national environmental standards

• High-tech eco-engineering solutions

• City-wide environmental monitoring and purification systems

Longking is often present where the most complex environmental challenges arise—heavy industrial zones, coal-energy sectors, metallurgy, and large manufacturing clusters.
