The aim was to provide a wide range of thermal and flow regimes necessary for experiments on HeII hydrodynamics and heat transfer as well as to test the realistic cryogenic equipment. The cryoblock is added to the 300 W / 4.5 K helium refrigerator to fulfil this task. This cryoblock contains series
