Abstract
Provided is a novel system for delivery of a gas from a liquefied state. The system includes: (a) a cabinet having a first and second panel disposed therein; (b) at least one compressed liquefied gas cylinder corresponding to each panel disposed in the cabinet; (c) temperature and/or pressure sensors disposed on each the cylinder; and (d) a controller for monitoring and adjusting the energy input into each of the cylinders based on the temperature and/or pressure in each of the cylinders sensed by the temperature and/or pressure sensors.

A system for controlled delivery of a gas from a liquefied state, the system comprising:
- (a) a cabinet having a first and a second panel disposed therein;
- (b) at least one compressed liquefied gas cylinder corresponding to each said panel disposed in said cabinet;
- and
- (c) sensors selected from the group consisting of temperature sensors, pressure sensors and combinations thereof disposed on each said cylinder;
- and
- (d) a controller for monitoring and adjusting an energy input into each of the cylinders based on a value in each of the cylinders sensed by said sensors;
- (e) means for programming a low and a high temperature set point of said compressed liquefied gas cylinder disposed on a respective said panel;
- and
- (f) means for switching between said first and said second panel upon reaching either a low temperature set point or a high temperature set point in said at least one compressed liquefied gas cylinder.
A method for delivery of gas from a liquefied state from a gas cabinet at a continuous flow in a controlled manner, the method comprising:
- (a) providing a cabinet having a first and a second panel disposed therein;
- (b) supplying a compressed liquefied gas from at least one gas cylinder associated with one of said first or second panel;
- and
- (c) delivering a controlled amount of energy to said at least one gas cylinder associated with one of said first or second panel and thereby increasing the flow rate of the gas withdrawn from said cylinder.
