A method for controlling a compressor that includes a compressor element, whereby during a transition from full load or partial load to zero load, a process A is followed that involves: (1) reducing the inlet pressure; and (2) reducing the speed and/or the drive torque. During a transition from zero load to part load or full load, a process B is followed that involves: (3) increasing of the speed or drive; and (4) increasing the inlet pressure.

Method for controlling a compressor

Method for drying compressed gas using a dryer with pressure vessels. The method having the steps of guiding a first part of the gas to a cooler via a regulating valve, and of subsequently drying this first part of the gas in the drying pressure vessel; and of heating a second part of the gas so as to regenerate the regenerating pressure vessel. When the temperature in the regenerating pressure vessel rises above an upper limit value, the regulating valve will be gradually moved in the direction of the shut position and, when the temperature in the regenerating pressure vessel drops under a predetermined bottom limit, the regulating valve will be gradually moved in the direction of the entirely open position, which adjustment allows to set the compressed gas at a desired temperature.

Method for drying a compressed gas

Device for drying a compressed gas which consists of a compressed gas supply (), two pressure vessels (and) which are provided with an input (, respectively) and an output (respectively) and a take-up point () for users of compressed dried gas, whereby at least two layers of desiccant (and) are provided in the pressure vessels (and), a first layer () made of a waterproof desiccant and a second layer () which is not necessarily made of a waterproof desiccant respectively, and whereby the pressure vessels (and) are provided with a second input (respectively) for the supply of compressed gas to regenerate desiccant from the first layer ().

Device for drying compressed gas and method applied thereby

Device for drying a compressed gas in a non-dissipative manner, which mainly consists of a compressed gas supply (), at least two pressure vessels () with an input () and an output (), and a take-off point (), whereby the device () is additionally provided with a first distribution device () and a second distribution device () which is provided with one or several coolers () and whereby the device () can be controlled by means of nine or ten cut-off valves (-and).
