REDUCING OPERATING COSTS AND
CO2 EMISSIONS WITH ENERGIFY
Valuable energy is lost in pressure reduction stations, exhaust steam pipes and condensation systems. With Energify system, the company CFT offers a simple and robust solution for the cost-effective conversion of even slight pressure differences into energy. This saves electricity
costs and lowers CO2 emissions. The system performance is controlled precisely with sliding gate valves from Schubert & Salzer.
“A
t the start we always have to do some convincing”, says Selcuk Aslan, Energify project manager at CFT. “Our system is highly developed, but the
idea and the basic design are actually very simple. For that reason people are sometimes sceptical. However, once they have seen and understood
Energify, they are quickly convinced by the robustness and reliability of the technology – and that ‘simple’ is therefore also a great advantage.” With Energify, CFT offers a solution to challenges that almost all industrial companies are facing: the reduction of CO₂ emissions and the improvement of energy- and cost-efficiency. The innovative system utilises even slight pressure differences to generate
Energify demonstration system Muensterland (Copyright: Schubert & Salzer Control Systems GmbH): Depending on the running time, this system generates up to 175 MWh per year in a very small space. The amortisation time of the installation is then less than three years. Includ- ing all maintenance costs, over 270,000 Euros could be saved in 10 years.
power and feed it into the factory’s own grid. Such pressure differences exist in almost all industrial plants. They occur in pressure reduction stations and exhaust steam pipes as well as in condensation and back pressure systems – and in most cases the energy stored in the fluids goes to waste.
OPTIMAL UTILISATION OF THE ALREADY USED ENERGY

“Energify optimises the use of the already existing energy”, explains Maximilian Igelbüscher, project engineer at CFT. “In order to guarantee an uninterrupted process, our system is always operated in the bypass. The basic design is as follows: Steam, or a gas of any kind, is expanded to a low pressure level in a rotary piston expander. This generates mechanical energy. This energy is transmitted via a shaft to an asynchronous generator, which then inputs the
