In modern industrial and household refrigeration, the efficiency of thermal exchange directly correlates with energy consumption ratings, operational lifespan, and sustainable footprint. The Roll Bonded Evaporator stands out as a top solution due to its integrated fluid pathway design. Formed through roll-bonding two sheets of aluminum with a printed internal circuitry, then inflating the unbonded paths, this structure ensures optimal surface contact with minimum thermal resistance.
As cooling systems transition toward environmentally friendly refrigerants (like Isobutane R600a and Propane R290), structural integrity and absolute leakproof execution are critical. The high thermal conductivity of pure aluminum, combined with computerized inflation control, guarantees precise heat flux distribution. The result is a cooling performance that prevents temperature stratification in freezers, commercial display cases, and industrial cooling chambers.
Ningbo Taojun Refrigeration Equipment Co., Ltd., drawing on a 38-year history beginning with the Xiangshan Refrigeration Accessories Factory of Zhejiang University, provides precision engineering to meet these changing demands. Our production is characterized by strict structural monitoring, pressure threshold validation, and custom channel topologies to optimize surface temperature uniformity.
Our core production machinery is imported directly from Germany, integrating real-time pressure monitoring and digital dimensional tracing to achieve raw material tolerances within ±0.02mm.
Equipped with a 5D quality verification framework: high/low-temperature cycling tests at -35°C to 75°C for 500 hours, thermal shock, damp heat, and multi-stage helium mass spectrometer leak detection.
Exporting to Europe, North and South America, Southeast Asia, and the Middle East. Complete certification path including ISO 9001:2015, EU RoHS directives, and US UL listings.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in the scenic coastal district of Xiangshan, Ningbo. Established in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, our organization has grown over nearly four decades to become a leading comprehensive enterprise integrating technical research, manufacturing engineering, global sales, and after-sales support.
Our core product line includes copper filter driers, check valves, air conditioning service valves, wire-on-tube and plate condensers, high-purity brass/copper fittings, and customized roll-bonded aluminum evaporators. In 2021, Taojun was recognized as a National High-Tech Enterprise, reflecting our dedication to process innovation, manufacturing upgrades, and advanced administration.
By using premium raw materials—including Japanese import liquid crystal components and European adhesives for specialized thermal films, and strict metallurgical controls for our copper and aluminum tubes—we produce reliable cooling elements under the "Lingshan" and "Taojun" brands. We are strategic suppliers to industry leaders, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Taojun specializes in designing, prototyping, and mass-manufacturing refrigeration components for household, commercial, and industrial HVAC systems. Our specialized products include copper filter driers, receiver tanks, condensers, capillary assemblies, and customized roll-bonded evaporators designed to operate efficiently under high-pressure conditions.
Our copper filter driers absorb moisture and acid, filtering out micro-impurities within the refrigerant cycle. These are standard components in domestic refrigerators, commercial food freezers, ice makers, and mobile climate control systems.
We work closely with clients' engineering departments, offering full CAD customization for plate configurations, inflation channels, connection tubes, and brackets to ensure drop-in compatibility at your assembly facility.
