ECS-M1V

ECS-M1V

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
