Agroeco-Yug, a Russian company engaged in pig slaughtering and processing, has signed a contract with Düsseldorf, Germany-headquartered GEA for the supply, installation and commissioning of an extensive cooling system including blast freezers at a state-of-the-art plant to be built in the Voronezh region. Scheduled to come on line in 2020, it will have throughout capacity of up to 600 pigs per hour.

Agroeco is the largest enterprise of its kind in the area, where the group operates 11 modern pig farms, genetics and selection center, and a high-tech feed mixing plant with an elevator.

The NH3 circuit’s refrigerating capacity is 6,500 kW at T0=-11 and a further 6,500 kW at T0=-14. In order to reduce the losses incurred in transforming electricity, as well as in the cost of constructing the transformer substation, it was decided that high-voltage motors (10 kV) would be installed on the compressor units for the NH3 circuit. For the receptacles of the -44 and -29 circuit, CO2 is used as the working substance, whereas for medium-temperature receptacles, an aqueous solution of propylene glycol, cooled to -8°C, is used.
