A process is provided for production of a refrigerating circuit comprising non-evaporable getter material, wherein said getter material, previously introduced into the same circuit, is heated to a temperature of at least 200° C. during or immediately after the circuit evacuating step, at a residual atmospheric gas pressure of not less than 10 mbar, before introduction of the mixture of cooling fluids and before the circuit sealing. Preferred is the use of zirconium-based getter alloys.
