Sanitary module

An important component of improving the comfort level of the Passenger Car is to improve the sanitary and personal services for passengers. The solution of this task is the project of developing a sanitary-hygienic module for the car.
The module is installed in passenger carriages of trains of locomotive traction, diesel and electric trains in order to ensure the sanitary and hygienic conditions of the stay of passengers and train crews during the trip, as well as environmental protection of the environment.
The module is designed to receive and remove by means of intensive dosed flushing with water the waste of human life in the storage tank and create the necessary comfort conditions.
The module is supplied with electricity and water from the sources of the car.
The equipment of the module provides automatic control of the flush preparation system, lighting, module ventilation and heating of the storage tank and pipes, as well as the issuance of light signals about the functional state of the electrical equipment.
Using the diagnostic module installed in the control panel, it is possible to perform diagnostics in various operating modes of the toilet system equipment.
Modern interior design of the sanitary module, color solutions, lighting solutions, quality sanitary fittings create the most comfortable conditions for passengers.
The module is able to take up to 20 people for one hour of the trip.
The service life of the sanitary module is 40 years.
