A pressure control manifold then controls the gas pressure that is fed to the process or application. Vaporizers convert the liquid oxygen into a gaseous state. This space keeps heat away from the liquid oxygen held in the inner vessel. Between the vessels is an annular space that contains an insulating medium from which all the air has been removed. There is an inner vessel surrounded by an outer vessel. The cryogenic tank is constructed, in principle, like a vacuum bottle. A typical storage system consists of a cryogenic storage tank, one or more vaporizers and a pressure control system. Liquid storage is less bulky and less costly than the equivalent capacity of high-pressure gaseous storage. Oxygen is often stored as a liquid, although it is used primarily as a gas. The product also requires special equipment for handling and storage. Liquid oxygen has a boiling point of –297☏ (–183☌).īecause the temperature difference between the product and the surrounding environment is substantial-even in the winter-keeping liquid oxygen insulated from the surrounding heat is essential. Cryogenic liquids are liquefied gases that have a normal boiling point below –130☏ (–90☌). Vessels should be manufactured to American Society of Mechanical Engineers (ASME) codes and designed to withstand the process temperatures and pressures. Equipment used in oxygen service must meet stringent cleaning requirements, and systems must be constructed of materials that have high ignition temperatures and that are nonreactive with oxygen under the service conditions. Materials that burn in air will burn more vigorously in oxygen. Oxygen will react with nearly all organic materials and metals, usually forming an oxide. Although nonflammable, oxygen is a strong oxidizer. Liquid oxygen is pale blue and extremely cold. Oxygen is the second largest component of the atmosphere, comprising 20.8% by volume.

#CAIRE HELIOS H300 LIQUID OXYGEN TANK PORTABLE#
While other portable oxygen units have limited continuous flow operation, the HELiOS portable units feature multiple settings for continuous and demand flow modes. Whether they want to visit friends and family, shop, fish or golf-patients can have long lasting freedom without needing to refill their portable or bring along extra oxygen cylinders. CAIRE, Inc.'s HELiOS Marathon Portable Oxygen Unit gives oxygen therapy patients unprecedented freedom: It lasts up to 22 hours between refills yet weighs only 5.6 pounds fully filled! The HELiOS Marathon portable unit lets patients be out all day.
