Transfer Type Vacuum Toilet Intermediate Tank Train Vacuum Toilet

Transfer Type Vacuum Toilet Intermediate Tank Train Vacuum Toilet 

1. Brief introduction:

Our Transfer Type Vacuum Toilet (vacuum toilet with intermediate tank) ranks as the most popular train toilet system for China’s high-speed trains, EMUs and modern passenger rail vehicles. Unlike traditional direct-discharge vacuum toilets, it adopts a staged waste transfer structure with an intermediate buffer tank. Boasting high stability, low failure rate and easy maintenance, it is an ideal sanitary solution for global railway new builds and renovation projects.

2.Core Working Principle

Equipped with a proven intermittent vacuum transfer system, the unit forms vacuum pressure in the intermediate tank upon flushing to rinse the bowl and collect waste. After 6 flushes, internal pressure rises automatically to deliver waste from the transfer tank to the main wastewater tank. This buffered design prevents vacuum system overload and blockage, ensuring stable performance under frequent daily use and prolonging component service life.

3. Key Product Advantages

Field-Proven Reliability: Massively deployed on Chinese railway transit lines with mature technology, fully verified for long-term, high-frequency passenger operation.

Intermediate Buffer Tank Design: Absorbs instantaneous flushing pressure and waste impact, effectively avoiding odor leakage, clogging and frequent system faults.

Low Energy & Water Consumption: Eco-efficient operation with minimal resource loss, featuring low water, air and power consumption to reduce operational costs.

Wide-Voltage & Stable Power Adaptation: 24V DC wide voltage range (±30% tolerance) adapts to complex railway power conditions, with ultra-low standby and working power.

Lightweight & Space-Saving: Compact, lightweight structure enables flexible installation and convenient vehicle refitting, saving valuable onboard space.

International Railway Safety Standard: Fully compliant with EN 45545 fire protection standards, meeting global rail vehicle safety specifications.
