In 2023, the company Soko Engineering completed and put into operation the largest ammonia cooling mechanism for the company Delta Transportni Sistem – DTS, which is the leader in the field of logistics services in Serbia and the region. The distribution and logistics center in Stara Pazova, which is part of the portfolio of the Delta Real Estate Group, has been upgraded with the most modern technology of cooling systems.
Cold storages with two temperature modes occupy an area of 7,000 m² and are intended for storing different types of food products. The storages are alternative (two-mode) and can be cooled to -22/±0°C
The systems of both low and high temperature mode are made with direct ammonia evaporation in cold storages, which is the most energy efficient solution. In order to increase the energy efficiency of the system, waste heat was used to cool the compressor heads, which is used to heat the floor under the minus chambers. The cooling system is designed in accordance with the highest standards in terms of installation safety for people and the environment, as well as in terms of energy efficiency.
