LVYE is a national high-tech enterprise that integrates the collaborative innovation of "industry, academia, and research". With a long-standing focus on the customized development of non-standard equipment and the integrated design of advanced technical process packages, the company centers its core business on process-integrated energy conservation, comprehensive waste heat reuse, and resource utilization.

Leveraging the profound academic foundation of top-tier research institutions including Tianjin University and Hebei University of Technology, LVYE has built a robust R&D platform and secured over 30 patents for independent intellectual property rights.

Rooted in its proprietary core technologies, LVYE has successfully developed and industrialized a portfolio of key equipment, such as twin-screw process gas compressor systems, twin-screw vapor compressor heat pump systems, and twin-helix multiphase transfer rotor pump systems. These integrated solutions have been widely adopted across industries including petroleum, oil refining, chemicals, environmental water treatment, and steel production.

Notably, the company has attained first-tier supplier qualifications from major state-owned enterprises (SOEs) such as CNPC (China National Petroleum Corporation), Sinopec (China Petroleum & Chemical Corporation), and CNOOC (China National Offshore Oil Corporation).

Since its inception, LVYE has specialized in the machining and manufacturing of screw-type machinery, which served as the cornerstone of its growth. After more than two decades of development, the company launched a strategic transformation in 2016, expanding beyond standalone screw manufacturing into equipment production, turnkey solutions, and technical service provision.

Today, its products primarily serve the petroleum, oil refining, and chemical sectors, with R&D efforts concentrated on energy-efficient, eco-friendly, and low-carbon technical equipment and process solutions.

LVYE has been honored with titles including "Tianjin Municipal Innovative Enterprise", "National High-Tech Enterprise", and "National Innovative SME". It has also established long-term industry-academia-research partnerships with prestigious institutions: the National Distillation Center and Crystallization Center of Tianjin University, the National-Local Joint Engineering Laboratory of Hebei University of Technology, and the Institute of Seawater Desalination under the Ministry of Natural Resources, among others.

Boasting over 30 invention patents and certifications from multiple authoritative systems, the company’s R&D team comprises more than 20 professionals—including 3 PhDs and 4 Masters. Characterized by youth, expertise, and technical proficiency, the team embodies vitality and a proactive spirit.

LVYE’s core product lines fall into three categories: twin-screw process gas compressors, twin-screw vapor compressor heat pumps, and twin-helix multiphase transfer rotor pumps. Its advanced technical process packages focus on process-integrated energy conservation and resource reuse, covering heat pump distillation, evaporative crystallization, crystal form control, salt separation, and comprehensive waste heat utilization.

Currently, LVYE’s products and technical services extend beyond the domestic market to reach the Middle East, Russia, Central Asia, and Southeast Asia, delivering efficient, energy-saving, emission-reducing, and resource-recycling integrated solutions to global clients.

Over more than 20 years of navigating challenges and seizing opportunities, LVYE has successfully transformed from a single-equipment manufacturer into a total solution provider that integrates specialized equipment development and process design. Today, it stands as an industry leader in process-integrated energy conservation and comprehensive resource utilization.

In recent years, particularly in the field of waste heat utilization for energy conservation and emission reduction, LVYE’s process packages and equipment combinations have been deployed in over 30 projects. Clients using these technologies have achieved significant economic and social benefits, underscoring the value of LVYE’s products and expertise.

The company’s flagship twin-screw vapor compressor heat pump system plays a pivotal role in industrial waste heat recovery. Employing Mechanical Vapor Recompression (MVR) technology, the system efficiently recovers and recompresses low-grade steam—such as secondary steam, low-pressure pipeline steam, and flash steam—by repressurizing and reheating it for reuse.

LVYE’s dry oil-free twin-screw compressors are widely used in the petrochemical industry, excelling in the recovery, transfer, and pressurization of non-air process gases, hazardous gases, and inert gases. They have become the equipment of choice for transporting torch gas, desorbed gas, condensate gas, natural gas, process tail gas, and inert gases in China.

Its twin-helix multiphase transfer rotor pumps serve diverse industries including petroleum, oil refining, chemicals, water treatment, and steel. These pumps specialize in handling high-viscosity, high-gas-content, and solid-laden multiphase fluids, ensuring reliable mixing, transfer, and lifting performance.

Milestones & Growth

Our 20-year journey has been marked by setbacks and triumphs, missed chances and hard-won gains:

2003–2007 (Founding Stage): Overcoming initial hardships, we moved from a small workshop to a purpose-built factory.

2007–2013 (Steady Progress): We began rotor machining with our first rotor milling machine, developed proprietary rotor profiles, and undertook a localization project for military applications.

2013–2016 (Specialization & Breakthrough): We secured a contract with CNPC to develop special multi-purpose transfer pumps, achieved major successes in domestic oilfields, and launched mass production of twin-helix multiphase transfer rotor pumps.

2016–2018 (Transformation & Innovation): We shifted focus to process integration and waste heat recovery. In 2018, we developed and deployed China’s first high-temperature, high-pressure twin-screw vapor compressor—pioneering the reuse of waste heat and secondary steam. This system became our core product, establishing us as one of China’s earliest manufacturers of twin-screw vapor compressors, with waste heat utilization identified as our key R&D direction for the next 20 years.

2019–2020 (Global Expansion): We developed and trialed our first dry oil-free twin-screw compressor unit with full independent intellectual property rights, which was successfully exported to Central Asia—marking our first overseas deployment of core proprietary equipment. We then launched serialized and standardized development of these compressors, becoming a leading domestic manufacturer of small-displacement process gas compressors, with energy conservation and emission reduction as our core technology.

2025 & Beyond: The future holds great promise, and we remain committed to forging ahead.
