Anyone ever haul CO2? I have hauled chemicals and sand and beer, never co2. It seems like a scary commodity to haul and transfer. Any one with experience?
Its not that bad. If you can understand basic plumbing. Follow the liquid line from the tanker to the tank your filling and then the vapor line back to the tanker, making sure you have you valves set right. Most have gone to hydro pumps. Older trailers had either a gas or diesel pony motor to power the pump. Once you get it going just watch the pressures.
