Device for cool drying a gas that consists of a closed cooling circuit (2) with a compressor (3), and which further in the direction of flow (M) of the coolant successively contains a condenser (5), an expansion means (7) followed by an evaporator (8), that constitutes the primary part of a heat exchanger (9) with a secondary part (10) through which the gas to be dried is guided, and whereby there is a bypass pipe (17) in the cooling circuit (2) that can be closed by means of a bypass valve (18) with a valve element (23) and a pressure-sensitive element (30) acting on it that is exposed to a local control pressure in the cooling circuit (2), whereby the control pressure pipe (38) is connected to the closed cooling circuit (2) upstream of the outlet of the evaporator (8). |
