Wang Jian, founder of East-Alliance, stated: "The plate heat exchanger industry currently faces internal competition and product homogenisation. To address this, East-Alliance will pursue technological innovation and industry breakthroughs through the following three approaches: Firstly, adopting microchannel structures combined with asymmetric flow channel co-design, which significantly enhances heat transfer efficiency while reducing costs for customers; Second, leveraging fusion welding technology to develop corrosion-resistant brazed plate heat exchangers, significantly expanding into emerging sectors such as wind power, laser technology, new energy, food processing, and IT. Third, through panel optimisation and reinforced connection tube design, launching a series of ultra-high-pressure resistant models. The East-Alliance product portfolio has expanded from fewer than 20 initial models to 30 series, forming a comprehensive application solution system that delivers high-efficiency heat exchange support to numerous leading refrigeration equipment manufacturers worldwide.
As a longstanding exhibitor at China Refrigeration Expo, East-Alliance has utilised this international platform not only to showcase the technological prowess of ‘Chinese smart manufacturing’ but also to forge deep connections with global clients and partners. Moving forward, East-Alliance will further increase its investment in research and development, harnessing innovative technologies to inject momentum into the high-quality development of the global refrigeration and HVAC industry.
