Abstract: A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.

Abstract: Dryer for compressed air including at least one cooling unit (28), able to cool a refrigerant fluid circulating in at least one drying unit (22), provided with an air inlet (11) and an air outlet (13) and also comprising at least one circuit (18) inside which air to be treated circulates from said air inlet (11) to said air outlet (13). The dryer for compressed air comprises, along the circuit (18), at least one cooling apparatus (12), configured to cool the compressed air to positive temperatures, a few degrees above zero and near to freezing temperature, and at least one freezing apparatus (14), disposed downstream of the cooling apparatus (12) and configured to cool the compressed air to abundantly negative values.

Abstract: Cooling plant for a “cooled” fluid, able to cool and/or dry the fluid by means of cooling substantially to a pre-established temperature, the plant comprising a heat exchanger (17), to cool the fluid, by means of heat exchange with a “cooling” fluid inserted in a cooling unit (11) comprising a cooling circuit (13) able to feed the cooling fluid to the heat exchanger (17), the cooling unit (11) comprising at least a condensation device (15), able to take the cooling fluid to within desired parameters of pressure and/or temperature. The plant also comprises regulation means (19) able to detect the temperature of the fluid to be controlled, and to act on the condensation device (15) in order to vary the parameters of pressure and/or temperature of the cooling fluid.
