  • Publication number: 20130305745
    Abstract: A system for dispensing cryogenic liquid to a use point includes a bulk tank containing a supply of cryogenic liquid and a pressure builder that is in communication with the tank via a pressure building valve. The pressure builder uses heat exchangers to vaporize a portion of the cryogenic liquid as needed to pressurize the bulk tank. The pressurized cryogenic liquid is dispensed through a dispensing line running from the bottom of the tank. A vent valve also vents vapor from the tank to control pressure. Operation of the vent and pressure building valves is automated by a controller that receives data from sensors. The controller determines the required saturation pressure for the tank and varies the tank pressure to match and provide a generally constant outlet pressure depending on conditions of the cryogenic liquid.

  • Patent number: 8584473
    Abstract: The invention relates to a cooling apparatus, especially for cryogenically preserving biological samples, comprising a duct (5) for delivering a coolant (3) to a cooling chamber (1), a heater (6) that has an adjustable first heating performance (P2) for heating the coolant (3) delivered to the cooling chamber (1), a first temperature sensor (8-10) for measuring the temperature (T2-T4) in the cooling chamber (1), a second temperature sensor (7) for measuring the temperature (T1) of the coolant (3) delivered to the cooling chamber (1), and a regulator (11) for regulating the temperature. Said regulator (11) is embodied as a multiple regulator which detects several temperatures (T1-T4) as control variables and/or adjusts several heating performances (P1, P2) as manipulated variables. The invention further relates to a corresponding operating method.

  • Publication number: 20130232997
    Abstract: Described herein are systems and methods for cryogenic fluid delivery. The systems may include a pressure vessel containing a cryogenic fluid formed of liquid and vapor that is connected to a use device via a withdrawal line. The withdrawal line connects to the cryogenic fluid in the pressure vessel via two routes, a liquid tube and a vapor line. The vapor line may include a back-pressure regulator that opens the vapor line depending on pressure in the system. The withdrawal line may include a pressure relief valve that exerts pressure on the liquid tube. A bypass line may connect the withdrawal line to the liquid tube. The bypass line has a check valve that permits free flow of cryogen from the withdrawal line to the liquid tube via the bypass line while prohibiting cryogen flow from the pressure vessel through the bypass line. The methods employ the systems described herein.

  • Publication number: 20130205804
    Abstract: A handler includes a storage tank which stores liquid nitrogen, supply channels which supply refrigerant from the storage tank to inner passages of a first shuttle, a valve which opens and closes the supply channel, and a heat exchanger which has vaporization chambers with larger flow path cross-sectional areas than those of the supply channels to vaporize liquid nitrogen within the vaporization chambers. According to this structure, the respective vaporization chambers are filled with nitrogen gas produced by preceding vaporization. Thus, pressure fluctuations produced by successive vaporization of liquid nitrogen can be reduced. Moreover, nitrogen gas is supplied to the respective inner passages. Accordingly, excessive cooling for part housing pockets can be prevented.

    Abstract: A method for maintaining a subcooled bottom state or the natural convection current of a liquefied natural gas in a storage vessel by the use of an external heat exchanger. The liquefied natural gas is removed from the storage vessel and cooled in the external heat exchanger by a cryogenic fluid such as liquid nitrogen. The cooled liquefied natural gas is reintroduced back into the storage vessel thereby maintaining a subcooled bottom layer or natural convection current in the storage vessel.

  • Patent number: 8468839
    Abstract: A portable liquid oxygen (PLOX) unit and method of filling. The LOX unit includes a LOX container. An inlet line communicates LOX from a LOX supply to an the LOX container, and an outlet line communicates LOX from the LOX container ultimately for consumption by a user. A vent line communicate the interior of the LOX container to ambient atmosphere. A vent valve is coupled to the vent line to selectively communicate the LOX container to the ambient atmosphere. An auto shutoff assembly is associated with vent line to substantially block the vent line when the LOX in the LOX container reaches a predetermined level. A reset element associated with the auto shutoff assembly causes at least a portion of the auto shutoff assembly to unblock the vent line for subsequent filling.
