ECS-M1V

ECS-M1V Environmental Control System 

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

The ECS-M1V stands out from its competitors for its compact design (1,695 x 592 x 466 mm) and low weight (60 kg). The all-in-one cooling, heating and ventilation for this environmental control system allows for easy installation and for the pilot to maintain the cabin and cargo area temperature within the desired range (+15°C to +30°C), in both ground and flight modes. There is the additional feature of an independent control of the conditions within the cargo area, such as the ability to control the distribution air to the upper and lower ducts, or shut it off completely. 

PBS gives our customers the added value of allowing modifications and specifications in the process, to ensure that the ECS is optimal for the aircraft for which it is intended. You will work with our expert designers and technicians to create the ECS that is right for your airplane or helicopter.

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.
