Alternative drive technology & electrification
Alternative drive systems for railway vehicles are becoming increasingly important and are expected to replace diesel drives in the medium to long term. To further increase the environmental sustainability of rail as a mode of transport, the development of battery-electric drives, hydrogen drives, renewable fuels and hybrids and the electrification of the rail network is being driven forward. As a long-standing supplier, HYDAC is involved in many of these developments with its products, services and expertise.
Alternative drive technology: our product and service solutions
HYDAC cooling systems
Discover our efficient and reliable solutions that extend the service life of your system with low electrical conductivity for fuel cells. We supply turnkey systems for all of your railway technology's thermal management needs.
HYDAC pressure transmitters for hydrogen applications
Due to the material used, our HDA 8400 series is particularly suitable for measuring the pressure of hydrogen storage tanks and is installed on OTVs (on-tank valves). The EC 79/2009 certification means that the sensors can be used in ECE R 134 systems. They reliably measure the inlet and outlet pressures on your pressure regulators or the inlet pressures of your fuel cell system.
HY-ROS mounting solutions for climate-neutral technology
We supply you with all kinds of mounting technology as our solutions are designed to ensure that pressurised gas tanks (type I-V), battery systems, thermal management components and TPRD sensor and cable holders are securely mounted. We also offer reliable options for guiding and tensioning high-voltage cables and supply cables. Whether it's band straps or neck mounts – HYDAC relies on fully automated in-house production.
HYDAC media management for hydrogen applications
Whether it's hydrogen ball valves or coaxial valves, we supply you with a broad product range for your media management. Our hydrogen ball valves offer excellent sealing properties and are extremely reliable. Our CX valves are completely leakproof, pressure-relieving and back-pressure tight to ensure optimum functioning despite the variable density of the hydrogen and to prevent hydrogen embrittlement.
HYDAC analysis service to determine H2 quality
Even the smallest impurities in hydrogen can cause serious failures. With the help of our PSA particle sampling adapter, it's possible to sample the hydrogen right at your site and check for any particulate contamination in the lab. Early detection of possible contamination ensures your system availability and prevents damage to your systems.
Railway vehicles
All over the world, city trains, underground trains, freight and passenger trains, railcars and locomotives run with components and systems from HYDAC. Whether it's with a traditional diesel drive or electric drive, battery-electric or fit for the future with hydrogen power – with our product range for railway vehicle technology, HYDAC enables a high degree of safety and operational efficiency. The components fulfil all important standards, such as the European standards for fire protection (EN 45545), vibration testing (EN 61373) and weld seam quality (EN 15085).

Whether it's an emergency function, equalisation of pressure peaks or temperature compensation and leakage oil compensation in the hydraulic bogie – our diaphragm accumulators and gas-tight metal bellows accumulators will meet your requirements. With their stand-alone energy supply, our piston accumulators also support the tipping cylinders on wagons that unload from the side.
HYDAC Flushing Unit Mobile
The brake systems in trains play a fundamental role in safety. And this is where our mobile, fully automated service unit can help you. The FUM cleans your hydraulic brake systems and lines and conditions your oil at the same time. This doesn't just save you oil changes. It also ensures the optimum performance of the brakes in your railway vehicle technology.
HYDAC sensors and measurement technology
For various monitoring and control tasks, such as monitoring brake pressure or controlling diesel preheating, we offer a comprehensive range of sensors with outstanding properties in terms of robustness, accuracy and EMC – in compliance with railway standards. Our powerful HMG 4000 portable data recorder is your reliable companion for service and maintenance, e.g. when carrying out brake tests.
Track laying machines & track maintenance machines
In the railway sector, there are a large number of work vehicles, service vehicles and special vehicles such as railway maintenance vehicles, track laying machines and railway cranes. The entire railway infrastructure depends on these special vehicles. To avoid line closures and complete track work as quickly as possible, individual vehicles and entire track construction trains are now highly specialised.
As an experienced supplier, we provide you with tried-and-tested components and systems for operational safety and performance that have proven themselves over many years of use by our customers, ensuring that railway transport operations always run smoothly and that you keep to your project plans.
