My driver‑side inverter air conditioner has passed inspection by the Air Conditioner Testing Center of the Aviation Industry Corporation.


In March 2002, the variable-frequency air conditioners for RS-series locomotives passed inspection by the Air Conditioner Accreditation Laboratory of the National Inspection Bureau for Import and Export Commodities—the Air Conditioner Testing Center of the Aviation Industry Corporation. This successful certification signifies that all performance parameters of our company’s RS‑series locomotive air conditioners have met national import‑export inspection standards. This not only ensures reliable products for our customers but also lays a solid foundation for future research, development, and next‑generation design of the RS‑series variable‑frequency air-conditioning systems.
