MESSKO® MTRAB® 2.5

Maintenance-free dehydrating breathers

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.

The MTRAB® 2.5 DB100 with alpha-control is a condition-controlled system, recommended for use on tap changers, arc suppression coils, air-filled cable terminal boxes and traction transformers. The desiccant is regenerated depending on the condition. Silica gel fill level: 1,1 kg with α-control.

Good to know: The main function of dehydrating breathers is to dehumidify the ambient air. As a result of the thermal compression of the insulation medium, the ambient air flows from the environment to the expansion tank of the transformer and tap changer (referred to as inhalation). During inhalation, moisture must be prevented from penetrating into the equipment with the air flow, as this reduces the insulating effect due to the contamination of the insulating medium.

The MTRAB® 2.5 DB100T with beta-control is a self-learning system, recommended for use on transformers with cyclic loads (network transformers, phase shifters, reactors). In addition to monitoring the humidity, the device determines a time window in which the oil conservator exhales and the desiccant is regenerated. Silica gel fill level: 1,1 kg with β-control.

The MTRAB® 2.5 DB200G with gamma-control is ideal for special applications, such as cavern transformers, furnace transformers and GSU machine transformers with aperiodic breathing behaviors. If the humidity level in the air flowing towards the transformer exceeds the standardized value, the desiccant chambers are regenerated in sequence. Silica gel fill level: 2 x 2,2 kg with γ-control.

Software
The MESSKO® MTRAB® 2.5 is equipped with a data logger of the latest generation as standard (software optional). The MTRAB® MSET software allows to monitor and analyze the device function and processes (dehumidification and regeneration) at any time. This provides additional safety when monitoring the equipment. In addition, you benefit from the long-term analysis – recording of the important operating parameter residual air humidity over a period of up to 10 years. 

Available languages: English, Chinese, French, German, Italian, Korean, Portuguese, Russian and Spanish

MESSKO® MTRAB® App
With the app, you can easily read out the entire data memory of your device on your smartphone. This requires that your MESSKO® MTRAB® 2.5 is equipped with NFC (Near Field Communication) and Bluetooth®. With this quick and easy connection between MESSKO® MTRAB® and smartphone, you can read out the data even without a notebook and can read out the last two days of the MESSKO® MTRAB® even when there is no power supply. 
 
Everything important always at a glance:
- Detailed information on device status (online and offline) plus error description with recommendations for action.
- Graphical display of the trend of humidity and temperature
- Creation of reports 
- GPS position of the location where the device is read out

How MTRAB® 2.5 works

1 / 3

Advantages over conventional solutions

MESSKO® MTRAB® 2.5 DEHYDRATING BREATHER CONVENTIONAL DEHYDRATING BREATHERS
+ A significant increase in operational reliability thanks to the maintenance-free system - High risk for transformers if maintenance is not or is improperly carried out
+ The lack of required maintenance means visual inspections can be reduced to a minimum. - Regular visual inspection required throughout the entire service life of the transformer to check the moisture level of the desiccant
+ Cost-intensive, regular replacement of the desiccant is no longer necessary. This significantly reduces costs. - Regular replacement of the desiccant required throughout the entire service life of the transformer
+ Sensor- and status-controlled regeneration of the silica gel - Enormous costs due to frequent refilling of desiccant, in particular in regions with high humidity
+ No environmental or disposal problems arising from consumed desiccant - Environmental impact, disposal problems, and considerable costs due to consumed desiccant
+ Greater efficiency during dehydration thanks to the large contact surface and the technical design - Ineffective dehydration
