A trap system for cryogenic environments, which brings a gas to a body of the same material in liquid form, allows the liquefied material in the gas bearing tube to pass through a submerged trap combining the newly condensed liquid with that in the reserve. With this apparatus, for example, pure cold Nitrogen gas can be condensed and recycled in a system requiring cryogenic liquid Nitrogen to start the process. This trap system can also be applied to other gaseous materials stored cooled beyond the condensing temperatures. The trap system brings the newly condensed material into the vessel of already condensed material. The gas that has not condensed into liquid, in the case of Liquid Nitrogen, will release into the atmosphere. It is expected that all the gas of the other material will liquefy and be part of the stored liquid because it is stored below its liquefaction temperature—here using Liquid Nitrogen chambers surrounding the vessel of the liquefied material. Also included are means to maintain a clean reservoir of cryogenic liquids providing means to remove debris on the surface, floating within the liquid and at the bottom of the reservoir. And yet more, keeping the liquid form of material is protected from the gas state material to prevent more rapid evaporation.
