RailMac Fuxing Standard EMU Toilet Waste Collection System

The Fuxing high-speed train is a trainset with completely independent intellectual property rights. Its design and manufacturing are entirely based on Chinese standards, and the product has reached international leading levels. As a crucial supporting facility for the standard high-speed train, Huateng Company participated in the entire development process of the standard high-speed train’s toilet system. Currently, all prototypes have been completed, and the train has obtained installation qualifications and performance records for all models from five major high-speed train manufacturers in China.
The toilet system of the Fuxing high-speed train generally adopts a vacuum transfer working principle.
The company provides customers with comprehensive life cycle services, from design to power system supply, installation and commissioning, to after-sales service, training, and spare parts supply, as well as troubleshooting and overhaul technical support. This full range of services ensures that customer equipment maintains high reliability and long-term operating efficiency during use.

Advantages of Fuxing Standard EMU Toilet Waste Collection System

Extreme water conservation, contributing to lightweight and energy-saving design: Each flush uses only 0.5-1 liters of water (1/10th the volume of a household toilet), significantly reducing onboard water storage, enabling lighter trains, lower energy consumption, and improved operational efficiency. A single trip on the Beijing-Shanghai line can save 4 tons of water, equivalent to 160 standard swimming pools annually, demonstrating strong adaptability to long-distance, cross-line resources.
Sealed and odorless, protecting passenger and maintenance health: Vacuum negative pressure suction of waste into a sealed waste tank prevents odor diffusion and backflow. Toilets do not need to be locked upon arrival at stations, eliminating embarrassment. Simultaneously, it isolates fecal pathogens, building a strong health protection barrier for passengers and track maintenance personnel.
Zero-emission track protection, cost reduction and resource reuse: Centralized waste storage and unified transfer at stations achieve zero emissions along the line, preventing corrosion of track components, extending maintenance cycles by more than 8 years, reducing costs by 30%, and converting waste into organic fertilizer, achieving a win-win situation for environmental protection and resource reuse.
Low energy consumption and high efficiency, adaptable to complex scenarios and highly reliable: The vacuum transfer design reduces compressed air consumption and equipment failure rate, and simplifies maintenance procedures; the water pressure is stable in high-altitude environments, and it has passed the full model certification of five major high-speed rail manufacturers, with excellent scenario adaptability and operational reliability.
