The system is designed for air-conditioning and ventilation of Mi-8/17/171 series helicopters, with the option of modifications for other applications.
  • Ability to draw air from both the APU and the main engines
  • Cooling, heating and ventilation in one compact system
  • Ecological operation - no coolant
  • Minimal power consumption
ECS-M1V modifies hot compressed air taken from the APU or the main engines to the required temperature of the air entering the helicopter cockpit. The system allows ventilation, heating and cooling of the pilot cockpit, passenger cabin and helicopter cargo area on the ground and in all its flight modes.
