Ever longer operating times and ever higher current densities lead to constantly increasing demands on operating equipment. The maintenance-free MESSKO® MTRAB® 2.5 dehydrating breathers continuously dehumidify and monitor the breathing cycle of power transformers – in all climatic zones. They regenerate themselves. This ensures maximum operating times and safety, and also massively reduces costs. The MESSKO® MTRAB® 2.5 devices have been proven over 90,000 times worldwide. The intelligent algorithm ensures that the IEC 60076-22-7 standard is complied with at all times. The MESSKO® MTRAB® 2.5 now offers an app function for easy data transfer.
