Engineered to withstand Queensland’s extreme subtropical climates and commercial cooling loads.
Brisbane’s unique climate profile—characterized by subtropical humidity, prolonged summer heatwaves, and sudden coastal storms—imposes unprecedented electrical and physical stress on air conditioning systems. Within commercial HVAC equipment, the air conditioning contactor is the most critical switching element, bearing the high inductive load start-up currents of heavy compressors.
When ambient temperatures soar to over 40°C in industrial hubs like Wacol, Pinkenba, and Eagle Farm, standard electrical components face accelerated thermal degradation. Poorly constructed contactors experience contact welding, high arc-erosion, and coil failures, leading to costly downtime for commercial facilities, food storage units, and high-rise CBD offices.
By designing and manufacturing contactors featuring high-purity silver-alloy contacts and advanced thermal heat-dissipation tracks, our systems ensure AS/NZS 60947-4-1 compliance. This level of reliability minimizes the risk of phase failure and safeguards high-value compressors across metropolitan Brisbane.

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 and development, production and 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.
Customer satisfaction is our unwavering pursuit. 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 quality management system certification, EU ROHS environmental protection directive certification, and US UL certification. The company always takes customer needs as the basis and continuously innovates management concepts to ensure efficient and stable development.
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. The company's goal is to support and cooperate with every sincere customer to achieve a win-win situation.
Delivering high-tech manufacturing capacity with strict laboratory-proven quality assurance.
Specialized copper filter driers, access valves, and customized electronic components.
Taojun is specialized in refrigeration parts for 38 years. Our catalog encompasses premium copper filter driers, access valves, condensers, and high-durability contactors.
Feature: TAOJUN copper filter driers are designed to absorb moisture and acid, and to filter out impurities. They are normally installed as an original component and replaced as a repair part for both domestic and commercial refrigerators, freezers, and air conditioners.
Uncompromising materials selection, advanced equipment, and stringent aging tests.
Our core manufacturing equipment is imported directly from Germany, ensuring absolute mechanical and dimensional precision.
We have 15 engineers in our R&D centre, all of them are doctors or professors from the University of Science and Technology of China.
Customized sizes, electrical ratings, configurations, and shapes are available. Welcome to share your project demands with us.
Our ITO film (no shrinkage, no color difference) and liquid crystal spacer (excellent uniformity) are imported directly from Japan; glue is imported directly from Europe; our liquid crystal temperature range is 70°C and protective film is resistant to high temperatures up to 80-90°C.
High & low temperature tests at 75°C and -35°C for 500 hours; thermal shock tests at 10°C-90°C for 30 minutes; damp heat tests for 500 hours; moisture removed by specialized oven. Smart films in sheets undergo a 24-hour aging test; smart films in rolls are tested with 100V high voltage to guarantee zero breakdowns.
Bypassing complex middlemen to deliver high-performance, cost-effective HVAC solutions directly to Queensland's industrial centers.
Australian refrigeration standards (AS/NZS 5149) and electrical installations standards (AS/NZS 3000) demand that electrical switchgear, including AC contactors, meet high thresholds of current tolerance, arc prevention, and insulation resistance. Taojun designs all export-ready contactors to exceed standard IEC/EN 60947 specifications.
By integrating Japanese raw materials and German automation lines, we produce contactors with exceptional anti-oxidation contact points. This ensures they operate reliably despite the high ambient humidity of Queensland, preventing contact pitting and premature system failures.
Located close to the Port of Ningbo, one of the world's leading deep-water shipping gateways, Taojun coordinates fast freight routes to the Port of Brisbane (Fisherman Islands). This direct maritime channel ensures bulk HVAC components, filter driers, and contactors reach distributors and OEM manufacturers in Queensland within highly competitive transit times.
Our flexible manufacturing capability supports bulk OEM/ODM customizations with a minimal MOQ of 500 units and rapid 72-hour global dispatch for stock items, allowing Brisbane contractors to maintain streamlined inventory levels without risking stockouts during peak summer demand.
From university-incubated roots in 1988 to a multi-national OEM supplier.
Establishment of foundational manufacturing plant and infrastructure expansion.
Introduction of the MES intelligent workshop management system for real-time QA tracking.
Next-generation automated assembly line and precision laboratory upgrades.
A world brand is supported by a corporate culture. We fully understand that our corporate culture can only be formed through Impact, Infiltration, and Integration. The development of our group has been supported by our core values over the past years:
