The solution for the disposal of wastewater and supply of drinking water
How the TUnit works

The TUnit from Vogelsang is a station for the extraction of toilet wastewater and supply of drinking water in train care service depot. The TUnit is available as a stand-alone station with an integrated rotary lobe pump or as a satellite service module in conjunction with a VacUnit as a centralized disposal system. All necessary elements for efficient supply and disposal are included. The standard model typically has a hose working radius of 7.5 m in all directions. The TUnit is particularly robust and is equipped with a mast with an integrated hose retraction system allowing for suspended hose management. All TUnit's are compact, easy to handle and suitable for outdoor use.

The maintenance of the TUnit is very simple thanks to its uncomplicated structure and easy access. This also includes the rotary lobe pump installed in stand-alone systems (TUnit SP), which consists of only a few components based on the Vogelsang QuickService concept.

Features of the TUnit

The TUnit is providing an automatic hose drainage ensuring a complete drainage of residual water after use. This is very important in freezing temperatures in winter.
Our products with VX series rotary lobe pumps are constructed according to an ingenious design concept, called QuickService design. This concept makes maintenance and repair of the equipment particularly easy. Systems are available again in a very short time, with downtimes minimized
On the TUnit and CabinetUnit, all the essential fittings and connections are contained in a housing to protect them from external influences and extreme weather conditions.
Various couplings for drinking water and wastewater are available to match the systems needs. The coupling for drinking water meets all the requirements for drinking water imposed by the German Federal Railway Authority (EBA).
For orderly and secure installation, Vogelsang normally supplies an installation frame. This frame, designed for setting in concrete, allows secure positioning and installation of the supply and disposal lines. If a height adjustment is required to bring the unit up to an existing working level, a customized adapter frame can be provided.

Options of the TUnit

For safety at work the CabinetUnit and TUnit can be equipped with rail-approved post top working lights.
Automation systems, such as preselection of filling volume and automatic switch-off on vacuum extraction stations, remote maintenance access, and automated operating data acquisition, allow economical use of resources and improvements in process efficiency.
If the systems need to be accessible for various different users, TUnits, CabinetUnits, and CleanUnits can be equipped with an authorization system. The systems are unlocked when the user logs in at a locally installed authorization module. A central operating data acquisition system can be implemented to provide the plant operator with required user & operational process data.
To ensure safe operation outdoors even at freezing temperatures and to protect the technical equipment from frost, optional electric heating elements can be used.
The systems can be fitted with an optional data acquisition system: important operating parameters such as filling and rinsing cycles can be recorded, saved, and analyzed.
If there is a need to record process data or to automate water filling or wastewater disposal processes, the TUnit and CabinetUnit can be fitted with the required technical equipment such as flow monitoring and control elements.
The drip-free suction coupling EasyConnect Plus makes easy work of hygienic disposal of sanitary collection tanks, even in sensitive areas such as workshops. The patented valve design ensures drip-free vacuum extraction. The installation of additional components at the rail car is not required if using the Vogelsang EasyConnect Plus. The exceptionally compact dimensions of the EasyConnect, together with its low weight and integrated hose swivel joint, make working with the EasyConnect Plus highly ergonomic.
The optional radio remote control enables functions such as the operation of valves or the automatic winding of hoses at the press of a button.
If the water tank aboard vehicle has an external interface for filling level monitoring, our water filling systems can be equipped with automatic switch-off device. This is done using so-called “ICE” radio modules, which are inserted in the corresponding plug contact on the train and wirelessly transmit the filling level in the drinking water tank to the filling station.

The ultimate solution for multiple station systems
Water supply and disposal station TUnit MP

The TUnit MP multiple station system is a satellite service station and is used in medium-sized to large storage and treatment facilities. The TUnit MP is connected to a central vacuum pumping station and is available in various designs.

Similar to the stand-alone TUnit SP, the TUnit MP multi point service station is also extremely user-friendly. The hoses, which are attached to a mast with automatic retraction, ensure a lar convenient hose operation in all directions and reliable and tidy hose stowage. This means that easy filling of water and disposal of toilet wastewater is possible even if the connections to the train are not in the immediate vicinity. Thanks to their automated retraction mechanism, the hoses are always ready for use. The TUnit MP service module is connected to a centralised vacuum pumping station and can therefore be designed to be particularly compact.

The stand-alone solution
Water supply and disposal station TUnit SP

The stand-alone TUnit SP is the perfect solution for small service stations or workshops. The TUnit SP contains a rotary lobe pump from the VX series for vacuum extraction and pumping of the wastewater. Required facilities to supply water are also available at the same module.

The TUnit SP is extremely user-friendly. Vacuum extraction and water hoses are mounted on a T-shaped mast. The hoses' automatic retraction mechanism ensures a convenient hose operation in all directions and reliable and tidy hose stowage.
