ERGO air conditioners of the ECO series are presented by 5 inverter models:

  • ERGO AC 0718 CHW
  • ERGO AC 0918 CHW
  • ERGO AC 1218 CHW
  • ERGO AC 1818 CHW
  • ERGO AC 2418 CHW

The outdoor unit operates in a wide temperature range: from 0 to + 43 ° C in cooling mode and from -7 to + 24 ° C in heating mode. Having set one of the modes - Comfortable Sleep or Auto, you can create the optimal balance of temperature and humidity in a room at any time of the day in the shortest possible time.

I FEEL function allows adjusting the temperature condition in the area where the remote control is located.

Due to a special function, the tilt angle of air blade is memorized automatically. This eliminates the need to readjustment the device after each launch.


The 3 in 1 multifunctional filter system cleans, disinfects and vitaminizes air. The catechin filter eliminates up to 95% of bacteria, the anionic prevents the appearance of new ones, and the filter with vitamin C vitaminizes air and softens it.

The “cold plasma” filter, ECO air conditioners are equipped with, eliminates the need for additional filtering and prevents the spread of dust, nicotine and pollen in the room.


ECO series air conditioners can be controlled from a smartphone with a help of a special mobile application. It allows to turn on and off the air conditioner, change modes of operation and temperature, as well as control switch on and off by day or week timer.

The application works in several modes:

  • “Local”: the smartphone and Wi-Fi module are in the same home network, and the air conditioner can be controlled via Wi-Fi without internet access.
  • “Remote”: smartphone and Wi-Fi module are on different networks, and the air conditioner can be controlled via the Internet via mobile network services or other means of communication.

For the connection with application on the internal unit of the air conditioner a Wi-Fi module should be installed. A Wi-Fi module is not included with the air conditioner, is supplied separately.


ECO series air conditioners are easy to install and maintain thanks to an improved design. They are fireproof, have a low noise level and therefore are ideal for both offices and residential premises.
