The performances of devices with liquid nitrogen as working cryoagent are explored .Devices have following performances: " Rnge of a thermal control -80 - 300 K; " The consumption of liquid nitrogen - is no more 0,2 Ltr/h. Created cryodevices ensure the high relation "signal "/ noise" for photomultipliers and other types of photodetectors. The receivedperformances of cryodevices on such parameters as stability of temperature, cryoagent consumption exceed the best world) analogs. The designed gears are necessary for usage in exploratory works, which are conducted in Ukraine, and by a rating "price / quality" are competitive in the exterior market.
