Substitution of Imported Cryogenic Equipment: Opportunities and Challenges for Domestically Produced

For a long time, the domestic market for high-end coating production lines and cryogenic water vapor cryopumps relied heavily on overseas brands. Due to shifts in the international trade landscape—characterized by extended lead times, high spare parts costs, and lengthy service cycles for foreign engineers—many manufacturers have begun evaluating domestic alternatives. Objectively speaking, early domestic cryogenic equipment suffered from issues such as temperature drift during continuous operation, refrigerant leaks, and high failure rates. However, after years of iterative development, leading domestic manufacturers have made significant strides in cascade refrigeration systems, refrigerant formulations, piping technology, and control systems. Some products now match the performance metrics of imports while offering local advantages: shorter delivery times, rapid on-site service responses, and lower spare parts costs. Yet, substitution is not merely a matter of swapping hardware one-for-one; it requires careful consideration of refrigerant compatibility with existing equipment, coil size matching, electrical signal integration, and the alignment of process parameters. A direct hardware copy-paste approach can easily lead to process fluctuations; success requires suppliers to possess a deep understanding of vacuum coating processes, rather than just refrigeration equipment manufacturing. Guangzhou Xieyi Automation’s WVCP series water vapor cryopumps hold multiple invention patents and CE and ISO9001 certifications. They have successfully replaced imported equipment in numerous projects across sectors such as optical filters, infrared technology, and capacitor film winding. Projects involve preliminary benchmarking tests under actual operating conditions, followed by post-replacement verification of pumping speeds, yields, and batch repeatability to ensure a smooth production transition. For export-oriented enterprises, domestic equipment also facilitates maintenance and support for overseas facilities, such as those in Southeast Asia. Ultimately, the competition in domestic substitution hinges not just on hardware specifications, but on process expertise, customization capabilities, and long-term after-sales service systems.
