Heating, ventilation and air conditioning systems (HVAC) represent an integral part of the modern real estate based on the latest technologies to maintain the specified air parameters such as temperature, humidity and chemical composition within a building, premise or structure in order to create a comfortable microclimate for humans, plants, animals and valuables. Automation of HVAC systems simplifies the management of all climate equipment in the building and saves the energy spent on creating and maintaining a comfortable microclimate.
Avandsis Group offers you innovative solutions in design and development of HVAC systems and sanitary engineering, performs installation and commissioning works, writing algorithms and programs that ensure integration of ventilation, air conditioning, heating stations, heating and refrigeration equipment of a building or an industrial facility into a single management complex as well as further maintenance of the installed systems. We offer you a high-performance, efficient and reliable equipment for both industrial and civil sectors from the world’s leading manufacturers of HVAC systems such as Daikin, WILO, York, Hitachi, McQuay, GREE, Grundfos, Danfoss, Fujitsu, Mitsubishi Electric, Toshiba, AstralPool, Rhoss, Carel and others.


Avandsis Group offers you various types of heating systems for buildings of any size and intended use in order to provide heat and create a favorable microclimate throughout the whole year. We install three main types of heating systems:

  • • Traditional heating: water heated in the boiler circulates through the system of pipes and radiators and provides heat in the rooms;
  • • Warm air heating: heated air is transferred to the rooms or premises through the air ducts;
  • • Direct electric heating: the room is heated by infra-red radiators, electric convectors and other electric heaters.

Using the automatic temperature controllers that react to the ambient temperature, modern heating systems maintain the required temperature in each room or premise and save up to 60% of energy resources.
We design a heating system along with the ventilation and air conditioning systems of premises during the early stages of the building or house construction and coordinate the work with the main construction contractors as installation of the traditional heating system requires the availability of separate boiler rooms.
We offer you the most modern self-contained heating units from leading manufacturers that will ensure warmth and comfort even during the worst frosts.


Air ventilation provides constant inflow of fresh air and is significant to maintain the necessary air cleanliness, temperature and humidity in the room. For complex projects of HVAC system development, Avandsis Group offers you high-quality ventilation equipment from leading manufacturers that will be installed and programmed by our qualified specialists.
We have the following basic requirements for ventilation systems during HVAC project design:

  • • supply of fresh air necessary for normal life and work of people;
  • • maintenance of air purity via filtration from various contaminants and toxic impurities;
  • • removal of moisture from structural elements;
  • • maintenance of the necessary air temperature and humidity;
  • • providing sound insulation in the rooms;
  • • saving of electric power due to heat recuperation between fresh and retracted air.

Avandsis Group develops projects on turnkey installation and automation of refrigeration systems, including delivery, mounting and commissioning works, programming and maintenance of various refrigeration equipment used for storage, cooling, freezing and shock freezing of various products. The temperature range in the installed refrigeration units depends on the set parameters and ranges from +15 to ˗40 °C.
An automatic control system for refrigeration unit usually contains a circulator pump, a compressor, a condenser, a receiver, heat exchangers, an evaporator, solenoid valves, temperature and security sensors, motors, magnetic starters and alarm elements.
Automation of refrigeration units allows to:

  • • collect and archive data on system operation;
  • • maintain the set temperature;
  • • control system performance;
  • • save significantly the energy resources;
  • • reduce cable and equipment expenses;
  • • improve the safety of the unit due to:
    • • monitoring system operation and preventing emergencies;
    • • elimination of human errors;
    • • reducing the risk of electric shock due to the use of a safe voltage of 12V.

During automation of refrigeration systems that operate using various types of refrigerants (ammonia, propane, freon, etc.), our specialists implement a reliable protection and alarm system to ensure timely notification of refrigerant leaks or other malfunctions of the system and prevent an emergency that is critical in explosive and harmful industrial atmospheres.
