More economical, more efficient and easy to get: Rapid Integration modular assemblies for EMU (Electric Multiple Unit) Cooling

Standardized but custom tailored: Rexroth modular cooling systems shortens typical design implementation, such that time to market is reduced to only three months.

Standardized assemblies by Rexroth reduces engineering time for traction cooling design and lowers life cycle cost

Rexroth significantly speeds up the engineering of rail vehicle cooling systems. With a modular cooling approach for EMU traction systems, three months’ time is all that’s needed to create a complete system. Such systems consist of radiators for a traction converter and transformer circuit that utilize industry proven and tested components normally used in high volume series production of mobile machinery. Manufacturers can take advantage of this approach to integrate tailored cooling systems into their vehicle cooling concepts. Bosch Rexroth acts as a system partner, taking responsibility for the configuration, system simulation and pre-assembly of the production-ready modules.

As a partner, Bosch Rexroth takes the pressure off rail vehicle OEMs by providing standardized cooling modules. Rexroth rail technology specialists configure ready-to-use cooling systems. The pre-configured cooling module systems are sized depending upon the required layout and traction drive cooling capacity needs. Either 1, 2, or 3 modules may be combined to form a system, reducing complexity and simplifying maintenance and repair.

Past experience shows that with Rexroth, rail vehicle manufacturers are able to reduce the time to market of the cooling system to three months. The specification and implementation of all mechanical and electric interfaces to the EMU are included. In addition, Rexroth simulates the function of the cooling system within the overall system of the rail vehicle and is responsible for the pre-assembly and testing of the assemblies. The modular cooling system meets all relevant European rail standards. For decades, Rexroth has been an established supplier of rail technology worldwide.

Identical part strategy reduces costs and simplifies maintenance

The modular concept based on an identical part strategy exploits the advantages of components from high volume series production by Bosch Rexroth. The components are produced in a cost-effective manner and are subject to the most stringent quality management methods developed in the automobile industry. In addition, Rexroth guarantees the long-term availability of components by obsolescence management. In this way, train operators reduce the maintenance costs of their rail vehicles over the entire life cycle.

The modular cooling system allows manufacturers to standardize all their cooling systems series and thereby unlocks additional potential for cost optimization and existing fleet modernization.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.
