Glen Rock, NJ-based PBI-Dansensor America has introduced the Total Gas Control Unit to safeguard the volatile organics that project flavor, aroma and taste of coffee. TGC is an electronically integrated system that automates the entire gas purging and monitoring process in a single unit. A combination of on-line gas analysis, off-line spot test analysis, electronic flow control of the gas supply and optional electronic controlled gas mixing maintains uniformity in gas packaging, reduces operator-dependent fault possibilities and reduces gas cost by avoiding wasteful overflushing. A pre-set program interfaces directly with the packaging machine to provide MAP parameters, gas blending ratios, gas alarm levels and the oxygen target level to be achieved in the package. The fully automatic TGC system requires no user interaction. Telephone: 201-251-6490; E-mail: sales.usa@pbi-dansensor.com; Web: www. pbi-dansensor.com
