The patent describes apparatus for preventing frost from forming on cold components in a moist atmosphere. The apparatus includes: a housing to enclose the cold components on which frost is to be prevented from forming, with the housing having an inlet and an outlet; a honeycomb mesh fixedly positioned across the entire outlet; a source of cold dry nitrogen connected to the housing inlet; and valving means, between the source of nitrogen and the housing inlet, to control the flow of the cold dry nitrogen from the nitrogen source to the housing.
