Explore our first tier of engineered components designed for high-efficiency DC cooler motors and cooling circuits.
In the modern HVAC/R era, thermal engineering demands absolute optimization. The global transition toward green technology has placed DC cooler motors and high-performance refrigerant filtration at the center of commercial and industrial upgrades. Because DC brushless configurations operate with variable speed control, they require highly stable companion components—such as low-loss motor capacitors, robust condensing coils, and precision-welded filter driers—to maintain high Coefficient of Performance (COP) values under fluctuating thermal loads.
Ningbo Taojun Refrigeration Equipment Co., Ltd. serves as a foundational manufacturer at this intersection. Since our inception in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, we have combined academic research with scaled manufacturing. Our products act as critical control, filtration, and heat-rejection elements in thermodynamic systems worldwide. We ensure that your compressors and DC cooling motors are protected from moisture-induced chemical degradation, avoiding premature failure and ensuring runtime stability.
A look into Ningbo Taojun's evolution from a specialized research workshop into a prominent global refrigeration manufacturer.
Established as the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Our research roots established our focus on technical precision and fluid dynamics.
Implemented early MES intelligent workshop management software. We refined our material tracking and optimized tool paths for copper and aluminum component extrusion.
Our manufacturing lines incorporate CCD optical inspection and robotic argon arc welding, meeting the standards of Tier 1 OEM HVAC brands.
We maintain a strict quality management system to support high system longevity.
Our raw material selections are strictly verified. Motor capacitor ITO film and liquid crystal spacers are sourced directly from Japanese suppliers to prevent shrinkage or color variation. Specialized polymer sealing adhesives are imported from Europe, providing thermal stability from -45°C to 120°C.
All finalized copper filters and brass fittings undergo 500-hour environmental aging tests from -35°C to 75°C, thermal shock cycles (10°C to 90°C), and 100V high-voltage insulation tests. This prevents structural leaks under typical refrigerant pressures.
Utilizing high-end German and Japanese CNC tooling, we process copper equal-tees, capillary tubes, and receiver shells within a precise tolerance of ±0.02mm. This ensures smooth brazing connections and consistent flow rates.
Our components are utilized in a variety of light commercial and domestic cooling applications.
From large cold-chain logistics hubs to compact household refrigerators, system components must function reliably under pressure. Ningbo Taojun's copper filter driers utilize a 3A molecular sieve paired with an activated carbon core to absorb moisture and acids within the refrigerant line, protecting compressors and ensuring the longevity of DC cooler motors. In industrial cooling and HVAC systems, our wire-tube condensers provide efficient heat dissipation, allowing fans powered by DC motors to run with lower power consumption and minimal noise.

Ningbo Taojun Refrigeration Equipment Co., Ltd. operates with a documented Quality Management System verified by Zhongci International and CNCA. Our operational standards satisfy RoHS, REACH, and UL regulations, enabling global partners to integrate our components into regional distribution networks without compliance delays.
As the HVAC/R industry transitions toward low-GWP (Global Warming Potential) refrigerants like R290 (propane) and R32, the demand for explosion-proof, high-pressure components is growing. Our R&D center, supported by engineers with backgrounds from the University of Science and Technology of China, is developing components optimized for these new systems.
Our roadmap includes the development of compact micro-channel heat exchangers and robust filtration cores capable of managing high-flow velocities. By optimizing thermodynamic efficiency, these components help reduce power requirements for DC cooler motors and compressors, supporting the global transition toward energy-efficient refrigeration technology.
