Two-Parallel Screw Compressor unit
Against the backdrop of the deepening "dual-carbon" goals and the steady increase in demand for cold chain logistics, Zhejiang Damai Cold Chain Equipment Co., Ltd. (hereinafter referred to as "Zhejiang Damai") officially announced the launch of its new generation of two-parallel screw compressors. The advent of this product not only marks a significant breakthrough for Zhejiang Damai in the core technology of parallel screw compressor units, but also injects new green, efficient, and intelligent momentum into the cold chain industry, driven by "new quality productivity."
Seizing Industry Opportunities, Responding to Market Needs with Technological Innovation
According to data from the China Federation of Logistics and Purchasing, the total demand for cold chain logistics in my country reached 381.4 million tons in 2025, a year-on-year increase of 4.5%. At the same time, the penetration rate of new energy refrigerated trucks has reached 44.86%, and digital transformation and green low-carbon development have become the main themes of the industry. As a leading brand in China's cold chain equipment industry, Zhejiang Damai is committed to providing efficient, green, and safe cold chain solutions for food, beverage, and frozen food companies. The newly launched dual-parallel screw compressor is another masterpiece resulting from the company's deep expertise in refrigeration equipment R&D and precise grasp of market trends.
Core Technology Breakthrough: Flexible Parallel Operation, High Efficiency and Energy Saving
The dual-parallel screw compressor features a design with two screw compressors operating in parallel. This allows for flexible adjustment of cooling capacity according to actual load requirements, achieving multi-level energy regulation (such as 50%-100% or 50%-75%-100%) to better match cooling demands under different operating conditions and significantly improve system operating efficiency. Compared to single-compressor operation, the parallel unit significantly reduces power consumption under low loads, effectively avoiding resource waste caused by over-engineering.
In terms of green energy saving, the product achieves greater cooling capacity and more efficient cooling effect by optimizing the screw meshing and rotational motion path. Simultaneously, the unit is compatible with various environmentally friendly refrigerants, actively responding to the industry trend of refrigerant recycling and green transformation. The deep integration of new energy and green, low-carbon concepts makes this product a model for achieving "dual-carbon" goals in the cold chain equipment field.
Intelligent Empowerment, Ushering in a New Chapter of "Smart Cold Chain"
Driven by the wave of digitalization, Zhejiang Damai has equipped its dual-parallel screw press with an advanced intelligent control system. The system can monitor various operating parameters of the unit in real time, has fault warning functions, and ensures safe and reliable operation. Users can issue commands with simple operations and can selectively achieve remote control and multi-machine joint control functions. This design not only improves the automation level of the equipment but also aligns with the current development trend of the cold chain industry leaping from a "cost center" to a "value hub."
Wide Application Scenarios, Supporting the Upgrading of the Entire Industry Chain
With its outstanding advantages such as a large cooling capacity range and high efficiency and reliability, the dual-parallel screw press can be widely used in large and medium-sized cold storage facilities, quick-freezing tunnels, refrigerated transport vehicles, and food processing. Whether ensuring the "last mile" delivery of fresh food e-commerce or supporting precise temperature control in the pharmaceutical cold chain, this product can provide stable and reliable cold source support.
A representative from Zhejiang Damai stated, "The launch of this dual-parallel screw press is a significant step in our company's practice of empowering cold chain equipment manufacturing with 'new quality productivity.' In the future, we will continue to increase R&D investment, promote the deep integration of AI and cold chain, and provide the industry with more intelligent, green, and efficient full-scenario refrigeration solutions."
With the convening of industry events such as the 2026 Cold Chain Trends Forum, "digital intelligence-driven" and "green and low-carbon" have become the two core engines for the high-quality development of the cold chain industry. The advent of Zhejiang Damai's dual-parallel screw press not only demonstrates the core strength of Chinese manufacturing in the refrigeration equipment field but also contributes Chinese wisdom to the resilience and sustainable development of the global cold chain supply chain.
