FIELD: refrigerating equipment.
SUBSTANCE: compressor arrangement with at least two compressor elements (2) connected in series and at least two coolers (12), of which at least two coolers are chillers with divided sections, which are divided into separate successive stages (16', 16ʺ), respectively, the hot stage (16') and the cold stage (16ʺ) connected in one or more separate cooling circuits (20), so that the compressed gas is sufficiently cooled between compressor elements (2) with the minimum flow of coolant to maintain the cooled gas temperature at outlet (15) of each cooler (12) below the maximum allowable value and thereby providing a necessary increase in the temperature of the coolant in at least one of above cooling circuits (20).
EFFECT: compressor device and the cooler used therefor are proposed.
