Explore our industrial-grade condensators, service valves, filtration driers, and installation hardware engineered for maximum COP and system integrity.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is situated in Xiangshan, Ningbo, a prominent center for maritime engineering and precision manufacturing. Founded in 1988, our operational foundation traces back to the Xiangshan Refrigeration Accessories Factory of Zhejiang University. This academic lineage drives our product development and engineering standards.
Over the past three decades, we have transitioned from a specialized refrigeration components supplier into a national High-Tech Enterprise (awarded in 2021). Our facilities integrate design, advanced thermodynamic testing, multi-stage production lines, and after-sales logistics support. Our domestic brand "Lingshan" is recognized for reliability in commercial and home cooling systems.





How our ISO 9001:2015 certified plant processes premium raw materials into durable refrigeration components.
Our core production lines utilize processing machinery from Germany. This equipment allows us to maintain tight tolerances down to ±0.02mm on split valve channels, tube extrusions, and fin positioning, ensuring consistent performance across high-volume production runs.
We source raw copper, aluminum coils, and brazing materials from certified suppliers. Our copper filter driers feature high-purity shells, while our liquid crystal spacer materials are sourced from Japanese partners to withstand extreme thermal conditions without degradation.
Every product batch undergoes testing in our laboratories. This includes 500-hour environmental chamber testing (-35°C to 75°C), high-pressure burst testing up to 60 Bar, and mass spectrometer helium leak checks to verify joint sealing integrity.
Ningbo Taojun Refrigeration holds registration number 41325Q00065R0S, verifying that our quality management systems for refrigeration valve assembly, filter drier production, and heat exchanger manufacturing conform to international standards.
The global heating, ventilation, and air conditioning (HVAC) sector is facing challenges from changing environmental regulations, shifting raw material costs, and rising demands for energy efficiency. Industrial buyers must look beyond purchase price to assess supply chain resilience, compliance with chemical regulations, and engineering consistency.
A key focus for HVAC components is material compatibility. Modern systems operate under high working pressures and use complex synthetic oils that can accelerate mechanical wear. Component manufacturers must ensure materials are clean, dry, and structurally sound. For example, residual moisture in a refrigeration circuit can react with ester lubricants to form corrosive acids, leading to compressor motor breakdown. Preventing these issues requires filtration driers with high moisture absorption capacity and low particulate release.





Regulatory frameworks such as the European F-Gas Regulation and the US AIM Act are driving the industry toward low Global Warming Potential (GWP) alternatives. Synthetic HFCs are being replaced by natural refrigerants, including Carbon Dioxide (CO2, R744), Propane (R290), and Isobutane (R600a), alongside HFO blends like R1234yf.
These eco-friendly refrigerants present new engineering requirements:
Condensers play a critical role in system efficiency. In residential air conditioning and commercial cold rooms, the finned tube condenser remains a standard heat exchanger design. Optimizing these systems requires managing heat transfer coefficients alongside air-side pressure drops.
Our engineering research focuses on three primary areas:
To achieve high component reliability, Ningbo Taojun implements a five-dimensional (5D) quality check framework throughout production:





Our long-term R&D focuses on developing smarter, more compact components. In collaboration with university partners, we are testing nano-engineered coating materials that reduce dust accumulation on condenser fins, maintaining high thermal efficiency over time.
We are also working on integrating micro-sensors into industrial filter driers. These sensors monitor internal relative humidity, pressure drops, and chemical contamination, providing real-time data to help operators schedule maintenance before a system failure occurs.
