<p>Device for cool drying gas includes a heat exchanger whose primary part is the evaporator of a cooling circuit. The gas to be dried is guided through the secondary part of the heat exchanger to cool the gas and to condense water vapour out of the gas. At least one bypass pipe is provided with a control valve which is controlled by a control unit as a function of signals received from a measuring element for measuring the lowest gas temperature (LAT) or the dew point of the gas in the secondary part of the heat exchanger. The measuring element is positioned directly inside the secondary part of the heat exchanger. Also provided is a measuring element for measuring the temperature of the coolant in the evaporator.</p>
