Abstract
A mobile CO2 filling system selectively fills onsite CO2 storage and dispensing systems with CO2. The system includes a mobile platform; a tank holding liquid CO2 mounted on the mobile platform; a flexible dispensing hose couple to the tank and configured to be selectively coupled to the filling inlet of an onsite CO2 storage and dispensing system; a pump selectively coupled to the tank; and a controller for controlling the filling of an onsite CO2 storage and dispensing systems with CO2 from the tank, wherein the controller is selectively designated by the user to operate in at least one pump assisted filling state and at least one gravity feed filling state.

A method for filing an onsite CO2 storage system comprising at least one gas CO2 storage cylinder, at least one liquid CO2 storage cylinder, a diverter valve, and a filling inlet, comprising the steps of:
- providing mobile CO2 filling system, the system comprising:
- a tank adapted to hold liquid CO2, the tank interconnected to a vehicle;
- a pump interconnected to the tank;
- a dispensing hose comprising a first end and a second end, the first end coupled to the tank;
- a fill gun interconnected to the second end of the hose, the fill gun configured to be selectively coupled to the filling inlet, the fill gun comprising a valve with a fill position and a venting position, and a vent for selectively venting CO2 from the hose while the fill gun is coupled to the filling inlet;
- a pressure sensor adapted to detect the pressure in the onsite CO2 storage system;
- and
- a selectable controller for controlling the filling of the onsite CO2 storage system with CO2 from the tank, the selectable controller interconnected to the pump and to the pressure sensor;
- wherein the selectable controller includes a plurality of pump assisted filling states to be selected by a user;
- and
- wherein the selectable controller is adapted to shut off the pump when a desired pressure within the onsite CO2 storage system is detected;
- coupling the fill gun to the filling inlet;
- selecting a pump assisted filling state using the controller to activate the pump and build pressure in the tank;
- selecting the fill position of the valve of the fill gun to deliver liquid CO2 to the liquid CO2 storage cylinder;
- deactivating the pump upon detection by the pressure sensor of a desired pressure within the onsite CO2 storage system;
- selecting the vent position of the valve of the fill gun to vent CO2 from the hose while the fill gun is coupled to the filling inlet;
- and
- disconnecting the fill gun from the filling inlet.
