In the chemical or electrochemical coating process which works at reduced pressure, the electrolyte fluid flows from an electrolyte vessel (1) via a lock appliance (8) and a three-way valve (6) optionally to a smaller (2) and a larger process chamber (3). The gases and vapours usually produced in electrolytic coating processes are effectively prevented by the reduced pressure from escaping into the environment. The appliance operates at a pressure of approximately 0.8 atm and, in order to maintain an optimum electrolyte temperature, contains heat exchanger devices (7, 20, 21). <IMAGE>
