As the food cold chain, chemical cooling, and supermarket retail industries continue to expand worldwide, the market for pipe ice machines, an important branch of artificial ice production, is experiencing a new round of rapid growth. The latest industry report shows that the global market for pipe ice machines exceeded $447 million in 2025 and is expected to exceed $743 million by 2035, with a compound annual growth rate of over 5.2%. In this growth wave, the Asia-Pacific region, driven by population growth and rapid urbanization, is expected to occupy 40% of the global market share by 2035, becoming the undisputed main engine. Technological iteration: From "ice making" to "intelligent ice", energy efficiency and intelligence are the core competitiveness.Currently, the pipe ice machine industry is undergoing a profound transformation from traditional mechanical manufacturing to efficient energy conservation and intelligent management. Against the backdrop of energy conservation and emission reduction becoming a global consensus, the new generation of pipe ice machines, through optimizing the evaporator structure and adopting efficient open-type screw compressors, significantly reduces the unit ice-making power consumption, meeting the strict cooling requirements of industries such as dyes and chemicals for reaction vessels. For example, the energy-saving pipe ice machine exhibited by Xie Ren Group, with its modular design and dual-loop heat gas de-icing technology, not only achieves rapid ice production and continuous ice supply, but also significantly improves energy efficiency through optimized refrigeration cycles. At the same time, the integration of Internet of Things and artificial intelligence technologies is reshaping the equipment operation mode. Modern pipe ice machines are gradually integrating remote monitoring and intelligent management systems, enabling fault warning and automatic adjustment, not only improving operational efficiency but also effectively reducing labor costs and downtime risks. For example, Guangzhou Koller Refrigeration recently obtained the "bucket pump liquid supply system" patent, through precise control of refrigerant supply and heat gas de-icing optimization, further enhancing the stability and energy efficiency of the system. Application scenarios are expanding deeply: not limited to aquatic products and edible iceDue to its unique hollow tube structure, pipe ice machines have a large heat exchange area, are not prone to melting, and have good fluidity. Their application fields have far exceeded the traditional scope of aquatic product preservation. In the food processing industry, pipe ice is widely used in meat processing, supermarket fresh product display, and restaurant beverage refrigeration; in the industrial field, pipe ice machines have become an indispensable "cold source cornerstone" in industries such as dye synthesis, concrete cooling, and chemical reaction vessel cooling. Research data shows that the food processing sub-market is expected to occupy 35% of the pipe ice machine application market by 2035, while stable demand in the fishing and chemical industries provides a solid foundation for the market. Regional pattern and enterprise trends: Made in China leads the worldFrom the regional competition pattern, China is not only the largest single market for pipe ice machines globally, with its share exceeding the combined total of North America and Europe, but also an important equipment exporter.

Recently, in response to the increasing demands for refrigeration in scenarios such as pre-prepared food industrial parks, aquatic product processing bases, large-scale cold storage logistics parks, and pharmaceutical constant-temperature storage, the new generation of screw parallel compression condensing units have been officially launched. The units rely on a multi-head modular parallel architecture, PLC intelligent group control, and efficient condensation integration design. With core advantages such as load adaptive regulation, redundant safe operation, high comprehensive energy efficiency, and convenient operation and maintenance, they provide a stable refrigeration solution for large and medium-sized low-temperature cold storage and rapid freezing production lines, helping to reduce electricity costs, stabilize storage, and ensure product safety in cold chain projects. In traditional large and medium-sized refrigeration projects, multiple independent single-unit units often have problems such as poor load matching, high idle energy consumption, no redundant backup, and complex machine room pipelines. Once a single unit fails, it can easily cause temperature fluctuations in the warehouse and the entire rapid freezing production line to stop, resulting in loss of high-value products such as aquatic products, pre-prepared foods, and pharmaceuticals. This screw parallel compression condensing unit adopts a multi-unit screw compressor parallel networking solution, equipped with an intelligent group control system, which can automatically schedule the start and stop of compressors and energy loading according to the real-time cold load of the warehouse area, achieving demand-based output of cooling capacity, avoiding energy waste caused by "big horses pulling small carts", and significantly reducing the overall energy consumption compared to traditional decentralized single-unit schemes. The core of the unit uses high-efficiency screw main units, optimizes rotor profile design, and is equipped with an efficient oil separation device, with high oil separation efficiency, ensuring long-term lubrication of the machine heads; the entire system integrates oil separators, manifold pipes, liquid storage, condensation heat exchange, and safety protection modules, with an organized and compact layout, significantly reducing the floor space of the machine room. The complete multi-level safety protection system covers multiple warnings such as high and low pressure, oil pressure, overload, phase sequence, exhaust temperature, and liquid strike protection, real-time monitoring the operation status of the unit; the unique redundant design allows other units to continue to undertake the refrigeration load when a single compressor is under maintenance or fails, without the need for overall shutdown, maintaining the control of the warehouse temperature, meeting the strict requirements of 24-hour uninterrupted production and storage in the cold chain. The unit is equipped with an industrial-grade PLC intelligent control system, supporting multi-level energy regulation, with the cooling capacity able to be smoothly adapted within a wide range, precisely matching the differentiated temperature zone requirements of preservation, refrigeration, and low-temperature rapid freezing; it supports local touch operation, remote data monitoring, automatic fault alarm, and operation data traceability, and can be connected to the factory's intelligent management platform, enabling unmanned operation and preventive maintenance, reducing on-site operation labor costs. At the same time, it is compatible with mainstream environmentally friendly refrigerants such as R507A and R404A, suitable for food and pharmaceutical industry clean control standards, and can be used in conjunction with rapid freezing tunnels, flat rapid freezing machines, and multi-temperature zone cold storage warehouses. The product is suitable for a wide range of scenarios, covering pre-prepared food processing industrial parks, aquatic product low-temperature processing, meat slaughtering rapid freezing, large-scale cold storage logistics warehouses, pharmaceutical GSP constant-temperature warehouses, chemical process cooling, etc., suitable for new cold chain projects as well as energy-saving renovations of old cold storage refrigeration systems, with modular design supporting on-demand expansion, and adaptable to the step-by-step expansion of enterprise production capacity. Under the background of the green and low-carbon transformation of the cold chain industry and the increasingly strict safety management of food processing, the screw parallel compression condensing unit, with its core advantages of intelligent group control energy saving, redundant reliability, and convenient operation and maintenance, solves the problems of high energy consumption, high shutdown risk, and difficult expansion in large and medium-sized refrigeration projects, continuously empowering the high-quality development of industries such as pre-prepared food, aquatic product cold chain, and pharmaceutical storage, and creating a stable, efficient, and safe underlying refrigeration equipment support for the cold chain system.
