Abstract: A compressor device includes a compressor for compressing a gas to generate a compressed gas having at least one compressor stage, and a cooling device including an oil cooler for cooling oil heated by the compressor, a compressed gas cooler for cooling the gas that is completely or partially compressed to form the compressed gas, and a housing cooler for cooling a housing or part of the housing of the compressor. The oil cooler, the compressed gas cooler, and the housing cooler each achieve cooling by a coolant flow consisting of a liquid coolant. The compressor device further includes a housing cooler control means for individually controlling the cooling flow through the housing cooler, and a cooling control configured to actuate the housing cooler control means in such a way that the coolant flow is controlled by the housing cooler independently of the cooling flow through the oil cooler.

Abstract: A compressor installation includes a compressor for compressing gas to generate a compressed gas, and a cooling installation having an oil cooler for cooling oil heated by the compressor, a compressed gas cooler for cooling the gas completely or partially compressed to the compressed gas, and a housing cooler for cooling a housing or part of the housing of the compressor. The oil cooler, the compressed gas cooler, and the housing cooler are each prepared to achieve the cooling by a coolant flow from a liquid coolant. In each case, the coolant flow of the oil cooler, the coolant flow of the compressed gas cooler, and the coolant flow of the housing cooler is an individual, actuatable control means to individually control each of the coolant flows such that a cooling output in each case is individually controllable for the oil cooler, the compressed gas cooler, and the housing cooler.

Abstract: The invention relates to a dry-compressing or oil-free compressor for generating a compressed gas and a method for oil separation for a dry-compressing compressor (1). The compressor has a compressor housing (4), a compression chamber (5) and at least one oil chamber (19a, 19b), in which an oil-lubricated bearing (18a, 18b) of the rotor bearing (16) is accommodated, as well as a shaft seal arrangement (10a, 10b), which is arranged between the oil-lubricated bearing (18a, 18b) and the compression chamber (5). The shaft seal arrangement (10a, 10b) has an outer seal (17a, 17b) facing the oil-lubricated bearing (18a, 18b) and an inner seal (12a, 12b) facing the compression chamber (5), wherein at least one sealing gas chamber (13a, 13b, 13c, 13d) for receiving sealing gas is formed between the outer seal (17a, 17b) and the inner seal (12a, 12b).

Abstract: A compressor system for compressing gases in a multistage compression includes a next-to-last compressor in a flow direction and a last compressor which are connected in series, one or more intercoolers between the next-to-last compressor and the last compressor, and an adsorption dryer connected downstream of the last compressor and designed as a rotation dryer having a rotating adsorption chamber. An inside of the adsorption chamber includes a regeneration sector and a drying sector. The regeneration sector is connected to the last compressor such that the compressed gas stream output from the last compressor is guided in a full stream principle through the regeneration sector. A bypass line which bypasses the intercoolers is situated between next-to-last compressor and last compressor, and includes a setting element to set the gas stream guided via the bypass line and therefore the regeneration entry temperature of the compressed gas in the regeneration sector appropriately.
