Passivated Flash Vaporizer

KEY BENEFITS

• Rugged, compact, SilcoTek® passivated Liquid CO₂ flash vaporizer–pressure regulator (VPR) designed to properly perform routine ISBT/CGA/EIGA sampling functions. SilcoTek® passivation prevents wall-adsorption or thermo-catalytic decomposition problems that can be experienced with volatile sulfur compounds and other important LCO₂ impurities.

• The VPR-HF series is used for several routine No-Haz sampling applications (e.g., flash-vaporized sample transfers into gas sampling bags or minicylinders) or to supply vaporized sample gas from large storage containers to analyzer systems via transfer lines.

• VPR-HF models can be equipped with 1/4″ or 3/8″ compression (tube) inlet ports, or special male high-flow quick-connect fittings. All models include an internal flow-control orifice, 1,900 psig (13,100 kPag) pressure relief assembly, thermal core insulation, protective heat-shield case, passivated pressure regulator, and outlet ball valve.
