Auto AC Conditioning Compressor For BMW F49 G11 G12 G30 G31 64527945819 Control Valve

Precautions for Use

1.Control the quality and quantity of refrigerant and refrigeration oil: The refrigerant must be R134a that meets the standard. The use of inferior refrigerant is strictly prohibited, otherwise it will corrode the internal components of the compressor and reduce the refrigeration effect. Refrigeration oil should be added in accordance with the specifications. It should neither be too little to cause insufficient lubrication and component wear, nor too much to result in excessive air conditioning pressure and reduced refrigeration efficiency. When replacing the compressor, the corresponding amount of refrigeration oil should be replenished simultaneously to avoid omissions.

2.When replacing, make sure to clean the system and check the accessories: If the compressor needs to be replaced, thoroughly clean the entire system including the air conditioning pipeline and evaporator first. If there is iron powder or blackened impurities in the pipeline, it is recommended to replace the condenser simultaneously. This is because the heat dissipation fins of the condenser are in a parallel structure and are difficult to clean thoroughly. The residual impurities will circulate into the new compressor and cause damage. At the same time, the dryer needs to be replaced to prevent impurities and moisture in the old dryer from affecting the operation of the new compressor.

3.Pay attention to the operating status on a daily basis: If abnormal sounds or vibrations are detected from the compressor during use, or if the cooling effect of the air conditioner suddenly drops, timely maintenance is required. Abnormal noises may be caused by mechanical issues such as internal bearing wear and loose pulleys, while poor cooling may be related to abnormal compressor pressure and refrigerant leakage. Timely troubleshooting can prevent minor faults from escalating into complete compressor damage.

4.Avoid improper operation to increase load: When the vehicle is idling, try to avoid keeping the maximum cooling mode on for a long time. At this time, the engine speed is low and the load on the compressor is relatively large. If this continues for a long time, it will easily increase the burden on the engine and may also cause the compressor to overheat. In addition, do not forcibly turn on the air conditioner when the air conditioning system malfunction (such as pipeline leakage) has not been repaired, to prevent the compressor from running dry and burning out due to lack of refrigerant or insufficient lubrication.

Regular professional maintenance: It is recommended that during the regular vehicle maintenance, the maintenance personnel check the pressure of the air conditioning system and the tension of the compressor belt. If the belt is loose, it should be adjusted in time. At the same time, professional equipment is used to check whether there is any leakage in the system to avoid compressor failure due to system abnormalities in advance.

        Since its establishment in 2003, Guangzhou Zhileng Technology Co., Ltd. has been deeply rooted in Guangzhou, China—a globally renowned core hub of the automotive industry. As one of the world's most thriving bases for the production and sales of whole vehicles and auto parts, Guangzhou has laid a solid foundation for the company to deepen its presence in the field of automotive air-conditioning compressors, thanks to its well-developed industrial ecosystem, efficient and convenient supply chain system, and global market reach. It has also provided the enterprise with unique industrial advantages for its subsequent large-scale development.       

        As an integrated industrial chain service provider focusing on the field of automotive air-conditioning compressors, the company has, over the years, concentrated deeply on the structure and working principles of compressors from world-leading brands such as Denso (Japan), Sanden, Valeo, Zexel, Calsonic Kansei, Panasonic, and Mitsubishi. To accurately master core technologies, it has not only invested substantial funds and human resources in conducting product dissection analysis, performance simulation testing, and reliability verification, but also, through continuous technical research and development, built a mature team of technical elites with both industry experience and innovative capabilities. Additionally, the company has established a data management system covering the entire product lifecycle of design, production, testing and after-sales service, providing scientific support for technological iteration and quality control.

        In the manufacturing process, the company also demonstrates strong capabilities: from the precision molding of housing die-casting and accurate machining of blanks to the fine grinding of high-precision components, a standardized and normalized production system has been established for every process to ensure product consistency and stability. Meanwhile, relying on a comprehensive range of professional testing and inspection equipment for components, coupled with a strict whole-machine performance verification process, each compressor must undergo thousands of hours of durability operation tests, ultimately meeting the OEM original factory matching standards — whether in the texture presentation of product appearance or the assembly accuracy of internal components, it is highly consistent with the original factory. It is precisely this "pursuit of excellence" in technical accumulation and "strict control" in production standards that has enabled the company to form an irreproducible technical competitiveness in the industry.

        The Japanese NASIDE brand compressors under the company serve as the core embodiment of its technology and quality. Boasting three core advantages—"reliable quality, stable operation, and ultra-low noise"—products of this brand have quickly built a premium reputation in the global automotive aftermarket. Furthermore, guided by the product philosophy of "originating from original factories and outperforming them," the brand has broken the industry's inherent perception of "replica parts" and won widespread acclaim from domestic and international customers. To further enhance the customer experience, the company has established a professional and efficient after-sales service system: from pre-sales technical consultation and in-sales installation guidance to after-sales fault response and maintenance support, a dedicated team is assigned to follow up promptly and resolve various issues customers encounter during product use quickly. This dual adherence to "quality and service" has enabled the products to be successfully sold to dozens of countries and regions, including Europe, the United States, the Middle East, Africa, and Southeast Asia, earning deep trust and long-term recognition from global customers.

        For years, "Originating from original factories and outperforming them" has been not only the company’s product philosophy, but also the core value that runs through its development. The company has always been driven by technological iteration and focused on process optimization, continuously enhancing the durability and adaptability of its products, and is committed to providing users in the global automotive aftermarket with higher-quality and more reliable automotive air-conditioning compressor solutions. Today, standing at the new starting point of the automotive industry’s transformation toward intelligence and green development, the company, with the enterprising spirit of "spreading its wings to strive for greater heights" (literally "spreading its wings to fight the sky"), sincerely extends a cooperation invitation to elites from all walks of life in the industry. It is willing to join hands with partners to deeply explore the market with a higher industry positioning and longer-term development goals. In the process of promoting the high-quality development of the auto parts industry, the company will help the "Made in China Dream" step onto the center of the world stage and shine with the strength of Chinese enterprises!
