• Company Overview and History:
Founded in 2002 as Yuhuan Yikang Copper Industry, Zhejiang Xuan'anju HVAC Technology Co., Ltd. has evolved into a trusted leader in the HVAC valve manufacturing sector. Located in Bingang Industrial City, Shamen Town, Yuhuan City, Zhejiang Province—just 910 meters from the highway entrance—the company spans 6 mu (approximately 4,000 square meters) with a production area of 9,000 square meters and employs 175 skilled professionals. Over two decades, the company has transformed from a small-scale copper accessory processor into a high-capacity manufacturer of complete HVAC systems. From 2002 to 2016, it focused on HVAC accessories with annual output under 35 million yuan. In 2016, rebranded as Yuhuan Yikang HVAC, it shifted toward finished products, achieving consistent growth: 38 million in 2016, rising to 73 million in 2020. By October 2021, after rebranding to Zhejiang Xuan'anju HVAC, the company achieved a record 91.28 million yuan in output value, surging to 120.05 million in 2022—a 23.96% year-on-year increase—and targeting 130 million for 2023. This exponential growth is driven by advanced U8 ERP integration across planning, procurement, logistics, quality, and financial management, enabling data-driven decision-making and operational excellence. The company’s strategic location, robust infrastructure, and deep industry expertise position it as a benchmark in the global HVAC component market.

• Research and Development Initiatives:
Zhejiang Xuan'anju HVAC Technology Co., Ltd. invests heavily in R&D to stay ahead in the competitive HVAC valve market. The company’s innovation engine is anchored in its 21 years of specialized focus on thermostatic valve series, allowing it to master complex thermal dynamics and precision engineering. A prime example is the development of its automatic thermostatic valves (TRVs), which utilize a bellows-based temperature-sensing mechanism to maintain indoor temperatures between 7°C and 28°C with a hysteresis of just 0.40 K. These valves are designed to respond within 20 minutes to temperature deviations, ensuring consistent comfort while reducing energy waste. The company also developed a proprietary calibration system in its TRV workshop, enabling precise adjustment of pressure differentials and flow rates—critical for compatibility with diverse heating systems. Real-world validation came when a major UK-based HVAC integrator adopted Xuan'anju’s TRVs in a large-scale residential retrofit project in Manchester. The system reduced heating consumption by 18% compared to older models, thanks to the valves’ accurate flow modulation. Additionally, the company’s R&D team collaborated with a German engineering firm to optimize the anti-scald function in its thermostatic mixing valves, resulting in a 30% faster response time during cold water interruption scenarios—proving the practical impact of its innovation pipeline.
• Upcoming Product Launches:
Zhejiang Xuan'anju HVAC Technology Co., Ltd. is preparing to launch a next-generation smart thermostatic valve set to debut in Q1 2024. This new product integrates IoT connectivity, allowing remote monitoring and control via mobile apps, and features adaptive learning algorithms that adjust temperature profiles based on user behavior and weather forecasts. The valve will be compatible with both gas-fired and solar heating systems, addressing growing demand for sustainable home solutions. The development was informed by feedback from key customers in France and Ireland, where smart home integration is rapidly expanding. During pilot testing in a 20-unit apartment complex in Dublin, the prototype demonstrated a 22% improvement in thermal stability and a 15% reduction in peak load demands. The company is also advancing a high-pressure thermostatic mixing valve (HP-T) specifically designed for commercial hot water systems, targeting compliance with NSF/ANSI 1111:2017 standards. This upcoming release underscores Xuan'anju’s commitment to not only meeting but anticipating global market needs, reinforcing its reputation as an innovator in intelligent temperature control solutions.
--- Production Excellence ---
• Advanced Manufacturing Processes:
Zhejiang Xuan'anju HVAC Technology Co., Ltd. operates a highly automated, lean-manufacturing production ecosystem across four core workshops. The Red Punching Workshop utilizes 3 automatic punch presses (390,000 pieces/month) and 6 manual presses (950,000 pieces/month), supported by 3 sand blasting machines capable of processing over 1 million parts monthly. The Metalworking Workshop leverages 96 CNC machines (2.2 million pieces/month) and 7 special machines, combined with gantry robots for complex body components—ensuring precision even at high volumes. Notably, the fully automatic NC machine line (41 machines) produces up to 1.5 million units per month, significantly boosting throughput. In the TRV Workshop, injection molding lines produce 500,000 valve bodies monthly, while dedicated calibration and bulb assembly lines ensure consistent performance. Final Assembly features 6 automated lines (780,000 units/month) and 2 manual lines, all following lean principles to minimize waste. A real-world case study from 2022 illustrates this efficiency: during a surge in orders from Russia and Italy, the company ramped up production by 40% without increasing staff, thanks to its flexible automation and real-time U8 ERP tracking. This agility enabled on-time delivery for a 15,000-unit order to a Czech distributor, earning praise for reliability and speed—key factors in securing long-term contracts.
• Quality Assurance and Testing:
Quality is embedded in every stage of production at Zhejiang Xuan'anju HVAC Technology Co., Ltd. The company maintains a state-of-the-art laboratory equipped with pressure testers, temperature cycling chambers, leak detection systems, and flow rate analyzers. Each batch undergoes rigorous inspection before shipment, including 100% functional testing of thermostatic valves and safety valves. For instance, during a routine audit in 2023, a batch of 10,000 pressure reducing valves failed initial pressure resistance tests due to micro-cracks in the brass body. The issue was traced to a supplier material inconsistency, prompting immediate corrective action and process revision. The company’s commitment to zero-defect production was further validated when a French client reported zero returns over two years—despite shipping over 200,000 units. The lab also conducts accelerated aging tests simulating 10 years of use in under 60 days, ensuring longevity. Furthermore, the company uses statistical process control (SPC) charts to monitor key parameters like O-ring seal integrity and spring tension, reducing defect rates by 65% since 2021. These practices, combined with real-time data from the U8 system, allow for continuous improvement and unparalleled product consistency—making Xuan'anju a preferred partner for global HVAC brands demanding reliability.
