The VCG generators are the safest and most advanced CO2 generators available today. Propane or natural gas, electronic ignitions eliminate the open pilot flame. Safety shut off in the event of a fall and dual redundant low-voltage solenoid valves add to safety. Clean & consistent burning. Variable CO2 output from 6-27 cu ft CO2/hr 12 ft hose/pressure regulator included Comes with: Comes with 2 clean burning brass burners pre-installed and the appropriate regulator & hose Electronic ignition controlmodule that eliminates the open polit flame some units use for safer operation. 2 brass burners have been designed to burn cleaner and produce a consistent blue flame. Tip-over switch automatically shuts off the entire unit in the event the unit fall or tips over. Dual solenoid valves provide redundant safety not found on most CO2 generators. Benefits: One of the most advanced CO2 generators available today.
