The dawning of a new age in temperature management of transformers


  • Highly intelligent cooling control networked with measurement, analysis and communication unit
  • Long-term use thanks to support for all major communication standards (DNP3, IEC 60870, IEC 61850, Modbus)
  • High quality, intuitive user interface
  • Software application can be called up in any conventional web browser
  • Optional: MESSKO® MControl® 7-inch touch display


MESSKO is setting new standards in power transformer cooling system control with the MTeC® EPT303. The modularly expandable, digital measurement unit impresses with highly intelligent solutions in the areas of safety, functionality and user-friendliness.

Developed from many years of experience, based on a completely new hardware and software platform and equipped standard with forward-looking features, the MESSKO® MTeC® EPT303 marks the switch from insulated cooling control to networked industry 4.0 application.

Brings the future to the surface

The user interface features intuitive operability and can be configured to meet individual needs. Alarm levels, triggers and warning notices can be configured as needed.

Optimal dosing, calculated control

Up to seven freely configurable cooling stages can be activated via relay contacts. The activation can be periodical or based on the load. A cyclical cooling group change is also possible.

More Input. More output.

The MESSKO® MTeC® EPT303 ensures you are well-equipped for the future. A wide variety of sensors and actuators are supported; this includes Pt100 in 2 and 4-conductor types and all standard types of thermal elements. Long-term use is also ensured thanks to support for all major communication standards.
