These products have gained strong market recognition for their optimized energy efficiency and wide operating range. Meanwhile, the company continues advancing the development of low-temperature two-stage screw compressors and subcritical CO₂ compressors.

Breaking Through the Industry Challenge

Subcritical CO₂ Compressors Lead the Green Transformation

With the implementation of the “Dual Carbon” strategy and the Kigali Amendment, traditional refrigerants are gradually being phased out. Natural refrigerants such as CO₂ are becoming one of the key solutions for sustainable refrigeration systems. Blait officially launched its new subcritical CO₂ reciprocating compressor series, featuring three major advantages:

High-Pressure Resistance with Enhanced Safety

The compressor adopts a high-strength body structure and crankshaft design, combined with dedicated safety valves, allowing it to operate reliably under high-pressure conditions.

Outstanding Low-Temperature Performance

Compared with conventional refrigerants, CO₂ refrigerant delivers 6–8 times higher volumetric cooling capacity and demonstrates superior COP performance in ultra-low-temperature environments below -35°C.

Wide Application Coverage

The compressor series is suitable for multiple refrigeration scenarios, including: Food quick freezing、 Cold chain storage、 Cold rooms and warehouses、Industrial cooling systems. This provides customers with both environmental sustainability and high-efficiency performance.

Academic Insights

Xi’an Jiaotong University Shared Cutting-Edge Research

At this conference, a representative from Xi'an Jiaotong University delivered a keynote presentation titled "Research Progress and Application Status of Refrigeration and Cold Storage Technologies under the Dual-Carbon Strategy." The presentation began with an overview of policy trends and industry developments, analyzing the profound impact of China's Dual-Carbon Goals and international environmental agreements on the refrigeration industry. It then highlighted the latest advancements in high-efficiency reciprocating compressor technology, focusing on improvements in energy efficiency and structural optimization, as well as recent research achievements in advanced heat exchange technologies for refrigeration and cold storage applications. Finally, the speaker explored future development prospects, examining both policy-driven opportunities and emerging technological directions. Combining academic depth with industrial insight, the presentation provided attendees with forward-looking technical perspectives and valuable practical references for the future development of the refrigeration sector.

Coordinated Innovation

Launch of New Refrigeration Valve Products

Alongside the compressor launch, Liyongda Valve also introduced a new generation of refrigeration valve products, including: Stop Valves、Pressure Regulating Valves、Inlet & Outlet Pressure Control Valves、Differential Pressure Valves. The company additionally showcased several newly developed products: Welded Pressure Regulating Valves、 Welded Oil Temperature Control Valves、 Extended Check Valves. These innovations further expand Liyongda Valve’s product portfolio in refrigeration system components and demonstrate the company’s strong R&D capabilities in refrigeration valve technology.
