Cryogenic capacities and tanks intended for oxygen and others cryoproducts require in reliable degreasing. The unit used now has a number of shortcomings. The new unit «UOR-80-141b» is created for its replacement. The methods of an intensification of heat exchange are used for increase of its productivity and simultaneous maintenance of admissible performance of weight and clearance characteristics. In unit is applied ozone-nondestructing solvent R141b.
