In commercial refrigeration and HVAC systems, the choice of compressor type governs overall thermodynamic efficiency, power consumption, and mechanical durability. However, the operational lifespan of any reciprocating, rotary, scroll, or screw compressor is heavily determined by the precision-engineered micro-components that protect its closed loop. From liquid line copper filter driers that eliminate moisture and acids to high-tolerance condensers and motor capacitors, the integration of supreme components is critical for achieving zero system downtime.
Widely utilized in residential air conditioners and commercial VRF loops. Requires precise refrigerant filtering, stable universal AC control systems, and low motor capacitor distortion to maintain continuous speed modulation.
The standard for low-temperature applications (domestic refrigerators, ice makers, freezers). Extremely vulnerable to liquid slugging and acidic moisture. Requires robust double copper filter driers to absorb residual system moisture.
Designed for heavy-duty industrial cold chains and water-cooled chillers. Demands premium-grade condensers and highly reliable access/stop safety valves to handle extreme pressure variables without system leakages.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful tourist city. Founded in 1988, its predecessor was Xiangshan Refrigeration Accessories Factory of Zhejiang University.
The company's leading products include: filter driers, check valves, air conditioning valves, condensers, brass and copper accessories, air conditioning cable ties, and other refrigeration accessories series products. After 30 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design, development, production, sales, and after-sales service of refrigeration accessories. In 2021, it became a national high-tech enterprise.
Our company is committed to technological and process innovation, equipment improvement, and the introduction of advanced management concepts to produce first-class products. With reasonable design, reliable quality, and perfect after-sales service, the "Lingshan" filter has become a well-known brand in the domestic refrigeration industry. The company has successively passed ISO9001:2008 / ISO9001:2015 quality management system certification, EU ROHS environmental protection directive certification, and US UL certification.
In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves, and other series of products. Over the years, it has established partnerships with well-known domestic and foreign home appliance enterprises such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui. The product sales network covers major and medium-sized cities in China and is exported to Europe, America, South America, Southeast Asia, the Middle East, Africa, and other overseas markets.
Taojun is specialized in refrigeration parts for 38 years. Our catalog is highly integrated to support different compressor types:
Designed to absorb moisture and acid, and to filter out system impurities. These are standard OEM components installed during system construction or replaced as premium repair parts for both domestic and commercial refrigerators, freezers, and AC units.
We supply high-efficiency wire tube condensers and copper fittings designed to reduce overall cycle resistance and accelerate heat exchange parameters.
Procurement engineers across Europe, North America, and Southeast Asia face complex operating parameters when securing components for different compressor types. Compliance with local regulations (such as the EU's F-Gas regulation, RoHS, and REACH) is no longer optional—it is a baseline requirement.
With the global phase-down of hydrofluorocarbons (HFCs), modern compressor platforms are shifting to natural alternatives like R290 (propane) and CO2 (R744). Sourcing departments must ensure that secondary components like molecular sieves, lubricants, and filter driers are explicitly rated for chemical compatibility with these new-generation fluids to prevent system corrosion.
Systems running R32 or CO2 work under significantly higher pressure parameters compared to older R22 configurations. Sourcing components made of certified, thick-wall high-purity copper guarantees that copper filter driers and condenser coils can safely withstand burst pressures exceeding 4.2 MPa without structural deformation.
Industry 4.0 demands IoT-enabled climate systems. Sourcing teams look for universal AC control systems and motor capacitors that integrate seamlessly with variable-speed drives (inverter compressors) to maintain system equilibrium under changing thermal loads.
We leverage high-performance German manufacturing machinery, strategic domestic academic partnerships, and strict testing protocols to guarantee robust product lifetimes.
Our core manufacturing lines are imported directly from Germany to ensure maximum precision and dimensional consistency across high-volume production runs.
We host 15 dedicated engineers in our R&D centre, including doctors and professors from the prestigious University of Science and Technology of China and Zhejiang University.
Custom shapes, specific weights (10g, 15g, 20g, etc.), and custom connections are fully supported. Share your conceptual drawings and let our engineers construct functional prototypes.
Our raw ITO films (offering zero shrinkage and color variance) and liquid crystal spacers (featuring superior uniformity) are imported directly from Japan. Our adhesives are sourced from Europe, enabling liquid crystal components to operate under a temperature range of 70°C and protective films to withstand thermal exposure up to 80-90°C.
All finished products endure a 500-hour environmental test under extreme conditions (-35°C to 75°C), thermal shock testing from 10°C to 90°C for 30 minutes, and a 500-hour damp heat test. Smart film sheets go through a 24-hour aging run, while rolls are subjected to 100V high-voltage insulation tests to assure zero electrical breakdown.
Our workshops run an integrated MES (Manufacturing Execution System). Sourcing managers can request chemical test reports and dimensional check sheets for every production batch.
Selecting the correct accessory components for your specific compressor type ensures structural integrity and high Coefficient of Performance (COP). Below is the engineered alignment index:
