Abstract: 
With the purpose of hardware support of long-term research experiments at temperatures 1.6÷350 or 77÷350 К cost-effective universal temperature-controlled cryosystem, working both with liquid helium and with liquid nitrogen more than 48 hours and characterized by the temperature stabilization up to ±0,05 K precision without modification of its construction is created. It is shown that the cons truction provides operation in a necessary temperature range with the accuracy up to ±0,05 К at minimum con sumption of cryocoolant.
Keywords: cryosystem, helium, long-term experiment, nitrogen, temperature stability, thermal control
