My driver's car air conditioner passed the inspection of the Aviation Industry Corporation of China Air Conditioner Testing Center
2002-03-18
In March 2002, the RS series locomotive frequency converter air conditioner passed the inspection of the air conditioner accredited laboratory of the State Administration of Entry-Exit Commodity Inspection and the Aviation Industry Corporation Air Conditioner Testing Center. Passing this inspection signifies that all indicators of the RS series locomotive air conditioner designed and produced by our company have reached the national import and export inspection standards. This not only provides users with reliable products, but also lays the foundation for our company's future research and development and replacement design of the RS series locomotive frequency converter air conditioning system.
High standards, strict requirements, and integrated products are used to capture the market.

On April 11, 2002, our company's RS-III type internal combustion and electric locomotive variable frequency air conditioning system passed the national scientific and technological commission Zhengzhou Railway Bureau's scientific and technological achievement appraisal. The passing of this appraisal indicates that our company's independently researched and designed RS-III type locomotive variable frequency air conditioning system has achieved and met the various requirements for the "integrated" production and use of the air conditioner and power supply system.
Consider the customer's needs and improve service quality
2004-02-16
In line with our philosophy of meeting user needs and providing better service, after careful consideration, our company has decided to gradually upgrade the RS-I type locomotive frequency conversion air conditioning system used by the first batch of users (Nanchang Railway Bureau) free of charge, starting from June 5, 2003. The system will be replaced with the RS-III type. This move has been unanimously praised by users and has established a good image for our company's After-sale Service!
