Explore our industrial grade refrigeration equipment, precision copper fittings, fan motors, and electric control units certified to international safety standards.
In industrial refrigeration and heating ventilating air conditioning (HVAC/R) engineering, the electric motor's efficiency is closely linked to its starting and running capacitors. High-quality motor run capacitors (CBB65, CBB60, CBB61) provide the phase shift needed to create starting torque and maintain smooth operation in single-phase motors, refrigerators, and cooling fan assemblies.
As a national high-tech manufacturing enterprise, Ningbo Taojun Refrigeration Equipment Co., Ltd. offers high-performance refrigeration parts, copper filter driers, stop valves, and electrical control systems. By combining advanced research and development with strict quality control, we ensure our components operate reliably under demanding conditions worldwide.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a scenic coastal manufacturing city. Founded in 1988, our predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over 30 years of development, we have grown into a comprehensive enterprise integrating design, development, production, and after-sales service for refrigeration accessories.
In 2021, Taojun was recognized as a National High-Tech Enterprise. We focus on technological innovation, process improvements, and modern management concepts. Our main products include: copper filter driers, check valves, access valves, condensers, brass/copper accessories, and electric cooling motors.
Our "Lingshan" brand filter driers have become a trusted name in the domestic refrigeration sector, backed by ISO9001:2008, EU RoHS, and US UL certifications. Through our brand "Taojun", established in 2012, we supply tier-1 global home appliance brands, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
How Taojun Refrigeration achieves strict performance metrics and long operating life across all component categories.
Our copper filter driers are designed with high-purity copper shells and filled with a 3A molecular sieve (water absorption ≥20%) combined with an activated carbon layer to capture moisture and filter out system impurities.
We source key raw materials globally. For specialized lines, we import ITO films (no shrinkage) and uniform liquid crystal spacers from Japan, high-durability adhesive resins from Europe, and high-purity copper tubing to ensure weld integrity and pressure resistance.
To eliminate leak pathways in high-pressure R32, R410A, and R134a systems, we use automated argon arc welding and verify joint integrity with high-precision helium mass spectrometer leak testing.
