Water service module TUnit

Overview
The TUnit from Vogelsang is a station for extraction of toilet wastewater and supply of drinking water in train servicing depots. Available as a stand‑alone station with an integrated rotary lobe pump (SP) or as a satellite service module connected to a centralized vacuum pumping system (MP). The standard model provides a typical hose working radius of 7.5 m and includes all elements required for supply and disposal. The TUnit is compact, easy to handle, equipped with a mast with integrated automatic hose retraction and suitable for outdoor installation.

Main benefits

• Combined water supply and toilet wastewater disposal in a single station
• Available as satellite module for centralized systems (multi-point service) or as stand‑alone unit
• Compact footprint for constrained depot spaces
• Safe and convenient operation with automatic hose retraction

Models
The TUnit is offered in configurations for different applications:

• TUnit MP (multi-point satellite module connected to a central vacuum pumping station) — variants: TUnit MPU Eco (manual), TUnit MPU Plus (electrical/semi-automatic control), TUnit MP Pro (monitoring/process automation)
• TUnit SP (stand‑alone) — includes an integrated VX series rotary lobe pump for vacuum extraction and wastewater pumping; water supply equipment integrated in the same module

Features

• Automatic hose drainage to remove residual water after use (prevents frost damage)
• Easy maintenance via QuickService design on VX series rotary lobe pumps to minimize downtime
• Protective cabinet housing fittings and connections for weather protection
• Various couplings for drinking water and wastewater; drinking water coupling compliant with German Federal Railway Authority (EBA) requirements
• Installation frame for secure setting in concrete; optional adapter frames for height leveling

Options

• Automation: predefined fill volumes, automatic shut-off on vacuum extraction stations, remote maintenance access, automated operating data logging
• Authorization systems for multi-user access control and central operating data acquisition
• Optional electric heating elements for frost protection in outdoor operation
• Operating data acquisition systems (filling and rinsing cycles, etc.)
• Flow monitoring and control elements for process recording or automating filling/disposal
• EasyConnect Plus: drip-free suction coupling for hygienic disposal; compact, lightweight, integrated hose swivel; no additional components required on the rail car
• Optional radio remote control for valve operation and automatic hose retraction
• Drinking water tank level monitoring via wireless modules (ICE) enabling automatic shut-off when tank is full
