Europe City Project
The Europe City project is a new build residential development featuring district heating. Located in a well-developed area of the capital with excellent infrastructure, the yard territory of the residential complex spans 10,000 square meters.
This elite multi-storey complex includes underground parking, office buildings, and built-in premises for various purposes such as retail space, a cinema, and recreation areas.
The Project
The complex consists of seven blocks: four blocks with 18 floors each, two blocks with 22 floors each, and one block with 25 floors. In total, there are 520 apartments across a total area of 3 hectares.
The Hydronic Challenge
The primary challenge of the project was the building’s height and division into zones by floors. The heating system was branched with zones featuring different pressures, necessitating the removal of air from the systems during start-up and ongoing operation. Additionally, the area designated for heating stations was limited, presenting further complications.
The Solution
To address these challenges, IMI specialists suggested the use of balancing valves and differential pressure regulators during the design stage. These components were essential in preventing the imbalance of heating systems maintain consistent pressure across each floor. Heat quantity regulation was managed in automatic heating stations via control valves. Differential pressure regulators stabilised the differential pressure within the heating station, enhancing the authority of the control valve. This approach ensured that the systems consume heat according to the design data and temperature conditions.
"The technical characteristics of the equipment meet the design specifications, and the building’s heat supply system is working in accordance with the design parameters. Based on our experience working with IMI and its partners, we plan to continue cooperation and collaboration on upcoming projects."

Project Parameters
Transfero stations were installed in each zone to stabilize thermal pressure fluctuations. Vento degassing units operated automatically, and the makeup of the heating systems was also automated. The installation of pressure maintenance stations effectively addressed the issue of limited space for heating stations.
The operation of heating units using weather-dependent automation and IMI control valves resulted in significant heat energy savings, reducing the energy costs for tenants.
