The GET turbine generator – an innovation that pays you back.
The green turbine generator is used to recover even small amounts of residual or waste energy and convert it into electrical energy. The performance range of the green turbine is between 3 and 350 kW. This electricity can be fed into the network or used for in-house industrial consumption.
As a leading manufacturer of expansion turbines, DEPRAG SCHULZ GMBH & CO. can be instrumental in increasing your energy efficiency. The goal of reducing CO2 emissions can therefore be achieved as part of the Germany Federal government’s requirements for climate protection. To date, DEPRAG has supplied and launched more than 300 turbine generators, as axial and radial turbines in a variety of processes, in series production worldwide.
The gas expansion turbine is a turbo machine. The specific fluid-mechanical design of the components for the turbine and generator will depend on your individual processing parameters. The product is mainly aimed at ORC system manufacturers and companies which are able to integrate an ORC turbine in their existing process or plant.
The unit consists of an expansion turbine and generator for optimal decentralised energy recovery for the power range 3 kW to 350 kW.
As a “waste to power” solution, the small, robust and compact turbine generator can be integrated peripherally anywhere small amounts of residual and surplus energy are left unused from a process.
A great variety of applications can be realised:
- Direct usage in open systems using pressure and temperature gradients, such as a gas expansion system
- Indirect usage in a closed energy generation cycle, such as an Organic Rankine Cycle (ORC) for cogeneration or combined heat and power plants (CHP) or waste heat utilisation in industrial processes

Exceptionally low maintenance
The turbine unit does not require a gear between the turbine and the generator. The generator’s rotor is located directly on the shaft with the turbine wheel and is driven by it. The GET turbine generator is therefore extremely low maintenance and ideally suited for continuous use.
The GET Green Energy Turbine is a turbo machine which can be used axially or radially with one or more stages. The expander converts the available energy into electrical energy due to the expansion of a gas from high to low pressure at constant mass flow. As an impulse or reaction turbine, the kinetic energy is passed into the jets and turbine wheel.
The DEPRAG gas expansion turbine recovers energy, meaning that even small amounts of residual process gas can be utilised. This means that energy recovery with the latest technology is an option for many sectors of industry. Our engineers will be happy to speak with you today to discuss whether your company is able to use our environmentally friendly turbine.
Energy recovery in energy-intensive industrial processes
In the glass, steel, ceramic or building materials industries, mediums such as compressed air or natural gas are used to supply the processes. The GET® turbine generator can convert the existing pressure energy into electricity and feed it into the electricity network or use it for in-house consumption. This prevents compressed air losses and increases the efficiency of the necessary pressure reduction in the natural gas network (expansion of natural gas).
Energy recovery from residual energy in power stations
When burning gas, e.g.in combined heat and power plants (CHP) which are operated with biogas, natural gas or synthesis gas, as well as in furnaces, waste heat from the motor cooling system or exhaust gas flow can be recovered. In a closed cycle, such as the Organic Rankine Cycle (ORC), an organic medium is vaporised (surplus heat in the cycle), expanded in the ORC turbine and converted into electricity using the generator.
Energy recovery through gas expansion in the natural gas network
Natural gas is pumped at high pressure from producing countries over thousands of kilometres through pipelines to reach the consumer. To feed it into regional networks, in which a lower pressure prevails, pressure must be decreased and the gas expanded. The transformation of pressures in the gas lines means that valuable energy is being lost, which the turbo expander is able to convert into electrical energy at low cost and without a large outlay.
DEPRAG SCHULZ GMBH u. CO. continually invests in research and development. It is our aim to give further impetus to the use of sustainable energy supported by new ideas and innovative solutions. We also rely on cooperation with external institutions and higher education facilities:
- East Bavarian University of Applied Sciences (OTH) Amberg-Weiden – Center of Excellence for Cogeneration Technologies (CeCoGen)
- Nuremberg Institute of Technology Georg Simon Ohm – Centre of Competence for Energy Engineering
- University of Bayreuth – The Center for Energy Technology (CET)
- Project „TurboSmart – adaptive micro-expansion turbine for energy recovery"
Funded by the Bavarian Research Foundation
The research project was led by the Center of Excellence for Cogeneration Technologies at the OTH Amberg-Weiden in cooperation with DEPRAG and the Center for Energy Technology at the University of Bayreuth. It dealt with the intelligent use and generation of electricity from process heat.
Funded by the Federal Ministry of Economics and Technology on the basis of a resolution passed by the German Parliament.
