Energy: day after day. For decades.
A power-plant drive knows no closing time: it runs as long as water flows, wind blows or gas is supplied — for decades, often in places hardly anyone ever visits. We design gearboxes for exactly this duty: robust, high in efficiency, serviceable.
- Continuous operation for decades
- wet · cold · full load
- high efficiency
Moisture, cold and varying loads.
Energy plants get no off-season — and the next planned access is often months away, in the overhaul window. If a gearbox fails in between, you lose feed-in, improvise service call-outs at hard-to-reach sites and open up the plant unscheduled.
- Continuous 24/7 operation without buffer time
- Lost feed-in remuneration with every failure
- Moisture, cold and varying loads
- Hard-to-access installation sites, long distances
Drives that last for decades.
We design energy drives for what counts over the operating life: service life in continuous duty, efficiency — and maintenance that fits the overhaul window.
Designed for service life
Generous safety margins on gearing and bearings, calculated on the real load spectrum — for drives that feed in for decades, not years.
Robust against the environment
Sealing and lubrication concepts are matched to moisture, cold and continuous load — even at hard-to-access installation sites.
Efficiency that feeds in
Every percentage point of efficiency counts over the operating life. We design for high efficiency and smooth running.
Where we are at work.
From hydropower plant to CHP unit — we build the right drive.
- Hydropower (Francis, Kaplan, Pelton) — turbine and gate drives
- Wind energy — yaw, pitch and main gearboxes
- Biogas and biomass — agitators and conveyors
- Combined heat and power plants — generator coupling
- Pumped storage and locks
- Photovoltaic tracking systems
The knowledge behind the design.
What matters for drives in energy plants:
- service-life design for continuous 24/7 operation,
- high efficiency — every percentage point feeds in more,
- robustness against moisture, cold and varying loads,
- serviceability at hard-to-access installation sites.
Designed for decades
Energy drives run without buffer time. Generous safety margins at the critical points and high-grade materials secure a long service life in continuous operation.
Efficiency = feed-in
Over the operating life, every percentage point of η counts. We design for high efficiency and smooth running — in multi-stage gearboxes, the efficiency of every single stage affects the overall efficiency.
Environment at the centre of the design
Sealing and lubrication concepts are matched to moisture, cold and continuous load — even at installation sites that are rarely accessible.
Efficiency η
The share of input power that arrives at the output as usable power. In multi-stage gearboxes, the stage efficiencies multiply — every percentage point counts in continuous operation.
Load spectrum
The time-based distribution of all occurring loads — continuous load, peaks, starting and shock torques. A serious design calculation works with the load spectrum, not with a single nominal rating.
Lubrication & sealing
Lubricant film, viscosity, lubricant selection and sealing concept determine service life and maintenance effort — matched to speed, temperature, mounting position and ambient conditions.
Condition monitoring
Monitoring of operating condition (e.g. vibration, temperature, oil) — detects damage early and enables planned rather than unplanned maintenance.
Retrofit
Modernisation or general overhaul of an existing drive instead of buying new — often with an improved design and shorter delivery time.
Drives for Energy & Power Plants — designed, built and tested in Marchtrenk, Austria.
Your partner for Energy & Power Plants.
Designed for your load profile
We calculate every gearbox on the actual load spectrum and the real operating conditions of your plant — not merely on a theoretical nominal rating.
Brand-independent service
We maintain, repair and replace gearboxes from all manufacturers — including reverse engineering of legacy equipment and spare parts to original dimensions or with an improved design.
Fast support when it matters most
Downtime does not keep office hours. Our service hotline is staffed around the clock — we assess the situation, agree the next steps with you and dispatch our service technicians right away.
Engineering from Austria
Design, manufacturing and service from a single source in Marchtrenk — since 1995. Short paths, dedicated contacts, full responsibility for the result.
Frequently asked questions.
/ 01Do your gearboxes withstand continuous operation in power plants?+
Yes — we specifically design energy drives for a long service life in 24/7 operation, with materials and sealing concepts that withstand moisture, cold and continuous load./ 02Do you also service existing plants from other manufacturers?+
Yes, brand-independently. We inspect, repair and retrofit gearboxes from all manufacturers — including reverse engineering and spare parts for older plants./ 03Can you replace an old hydropower or wind gearbox?+
Yes. We survey the existing gearbox, determine mounting dimensions and load case and deliver a fitting replacement — frequently with improved efficiency.
So your plant keeps feeding in — year after year.
Whether hydropower, wind or CHP: describe your plant and load case — we design the drive that will not derail your overhaul planning.
