Abstract
A fluid spray device system (1) 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 (22). The resultant fluid has throttling gas and cryogenic fluid components. Both the throttling gas and cryogenic fluid are preferably supplied from a single tank (11) and the cryogenic fluid supply is pressure-regulated and includes a triaxial delivery hose (33) having a return line with a back-pressure regulator (54).
