Biogas Power Plants
Biogas power plants are facilities that convert biogas, produced from the fermentation of organic waste, into energy. These plants require regular maintenance and repair. Maintenance and repair services include the periodic inspection, cleaning, and, if necessary, repair of biogas production units, gas purification systems, generators, and other equipment, enhancing the plant’s efficiency, ensuring safety, and guaranteeing operational continuity.
Independently of the brand and without power limitations, we carry out both planned A, B, and C maintenance as well as unplanned maintenance for all types of steam turbines and generators, acting as your fast and reliable solution partner with manufacturer supervisors, our team of expert engineers, and technical staff. In line with our company policy, we apply the highest standards of occupational safety, providing our employees with training before and during maintenance at scheduled intervals to create a more conscious and safe working environment. Units delivered to our company for maintenance are completed within the desired working periods, both through the care we show in scheduling and the precautions taken during the work process.
