ABSTRACT: "Refrigerator". The invention relates to a refrigerating device with a primary and a secondary refrigerating system, which are in heat exchanging contact with each other. The secondary refrigerating system is connected to a reservoir containing a control gas getter which can be heated for varying the amount of free control gas in the secondary refrigerating system, so as to control the temperature of the secondary refrigerating system. It is proposed to close the reservoir with a breakable seal, so that a getter container in the form of a cartridge is obtained. After the cartridge has been mounted on the secondary refrigerat- ing system the breakable seal is ruptured by raising the pressure.
