The Selenium Twins are two luxurious 34-storey residential blocks located in Fulya, Istanbul. They reside on a 29,000 m2 area of land owned by Besiktas JK football club that includes a 10-storey hospital building, 21-storey office building and 16,000 m2 supermarket.
Asçıoglu Construction Company had high demands for the Selenium Twins’ energy system. It selected Danfoss to equip the facility with a solution that boasts low operational and investment costs, and delivers consistent high comfort.
A total of 222 Danfoss flat stations power the supply of heat and hot water to the domestic towers. The flat stations, type Termix VMTD-F, consist of heat meters, motorized valves, balancing valves and pressure reducers. The buildings are installed with perfect remote meter reading technology, and use M-bus data transmission protocol to obtain data from Danfoss heat meters and water meters in order to generate a combined utility and energy bill for residents.Based on the success of the Selenium Twins project, Asçıoglu Construction Company has committed to replicate the same solution for two other projects – Selenium Panorama and Selenium City. This will equate to an additional supply of approximately 500 Danfoss Termix VMTD-F flat stations.
