MESSKO® MTRAB® 2.5 DB100 dehydrating breather

Maintenance-free dehydrating breather for transformers

Your benefits at
a glance

  • Maintenance-free dehydrating breather
  • DIN flange for optimal mounting
  • Test button for performing self-tests and indication of the current humidity level
  • Optional: Offshore model, filter heater for use in temperatures as low as -50 °C and a data logger
  • Optional: Modbus capability for Integration into monitoring Systems (e.g. ETOS®)
  • Optional: Protection of the electrical lines from damage (such as gnawing by animals)
 

The maintenance-free MESSKO® MTRAB® 2.5 DB100 dehydrating breathers of the Premium series feature a built-in heating element, which enables sensor-controlled dehydrating. This eliminates visual inspections that are required regularly and minimizes costs. The MESSKO® MTRAB® 2.5 DB100 dehydrating breather is available with an alpha or beta control system.

 

Areas of application: Dehydrating breather transformer accessories

MESSKO® MTRAB® 2.5 DB100 with alpha control system

The MTRAB® 2.5 DB100 dehydrating breather with alpha control system: Recommended for use with tap changers, arc suppression coils and traction transformers. Here, the dehydrating breather is heated, depending on conditions, by monitoring the humidity.

MESSKO® MTRAB® 2.5 DB100 with beta control system

The MTRAB® 2.5 DB100 dehydrating breather with beta control system: Self-learning system, which is recommended for use with transformers with cyclic loading. In addition to monitoring the humidity, it determines a time window in which the oil expansion vessel expels air and the dehydrating chambers are regenerated.
