Burj Khalifa, the world’s tallest building, is located in Dubai, United Arab Emirates (UAE). With a staggering 160 floors, reaching 828 metres, the building takes your breath away. Burj Khalifa is not only a world famous skyscraper, but also a building complex in downtown Dubai with residential buildings, office buildings, hotels and shops. Two of the residential buildings soaring to 35 floors and dwarfing many other high-rise buildings are balanced to perfection by an extensive Danfoss hydronic balancing solution. The solution provides more than 800 dwellers with a pleasant indoor climate even when temperatures rise to 40°C or above during the scorching hot summer months.

”In the design phase, we convinced the contractors to use AB-QM valves due to fast installation and short commissioning. But energy savings were also an important argument. Even though the energy prices are much lower in the Gulf States compared to e.g. Europe, the awareness of energy savings is increasing in the UAE and supported by the UAE government,” says Serhan Ismail Ozten, Area Sales Manager at Danfoss.

High indoor comfort and stable temperature

The most convincing argument in favour of the Danfoss solution was the high and stable level of comfort provided by the AB-QM installation. “When you set the thermostat the temperature will be stable due to the advanced balancing system. Even with varying outside temperatures and varying cooling demands when people are away, the delicate hydronic balancing installation will ensure the proper flow providing the desired level of cooling in every apartment,” explains Serhan Ismail Ozten who worked closely together with Mr. Abdul Latheef from engineering company WOTEK Co.

The perfectly balanced flow also explains the energy savings achieved by the Danfoss solution. When the flow rate is highly controlled and stable, the pumping required will be greatly reduced, resulting in significant energy savings. The AB-QM valves are even maintenancefree as they contain no movable parts. Furthermore, the design of the valves prevents clogging during everyday use.
