A fluid spray device system () that maintains a resultant fluid discharge, or a material onto which the resultant fluid is discharged, within a predetermined range of a set-point temperature by regulating the flow rate of a throttling gas using a proportional valve (). The resultant fluid has throttling gas and cryogenic fluid components. Both the throttling gas and cryogenic fluid are preferably supplied from a single tank () and the cryogenic fluid supply is pressure-regulated and includes a triaxial delivery hose () having a return line with a back-pressure regulator ().
