  • High flow rate transportable UHP gas supply system
    Patent number: 6614009
    Abstract: A high flow rate, transportable, ultra high purity gas vaporization and supply system is provided which includes a vessel suitable for carrying large quantities of a liquefied gas, valves to operate with liquid or gas phases, a loading/unloading unit disposed on the vessel for loading and unloading the liquefied gas to be supplied, and a heater containing heating elements permanently positioned on the vessel to supply energy into the liquefied gas. The heater causes the liquefied gas to be supplied through the loading/unloading unit as a gas. A heater controller is also provided which uses process variables feedback for regulating the heating elements to maintain and regulate gas output.

  • Bulk vessel heater skid for liquefied compressed gases
    Patent number: 6025576
    Abstract: A skid with built-in heating elements for heating and supporting a compressed-gas dispensing bulk vessel, or cylinder, while allowing for manipulation and transportation of the cylinder and skid assembly. The skid incorporates all of the features necessary for handling a cylinder while also providing a means for heating the cylinder in a controlled manner. The heater skid comprises a framework for receiving the cylinder and one or more heaters coupled to the framework so that the received cylinder is proximate to the heaters, thus, allowing the heaters to heat the cylinder. A control system for the heaters is also disclosed.
