A CO.sub.2 gas delivery valve is fluidly connected to a delivery outlet of the CO.sub.2 tank to regulate release of CO.sub.2 therefrom. The CO.sub.2 tank includes a pressure sensor for measuring a CO.sub.2 tank pressure. The controller is configured to control operation of the acid and carbonate pumps, and the CO.sub.2 gas delivery valve according to a user command signal, the CO.sub.2 tank pressure, or both.

An apparatus for applying carbon dioxide (CO.sub.2) in solid form to a target comprises an aggregated body production chamber for producing individual solid bodies of CO.sub.2 with defined shape using an endless type conveying member which carries a plurality of receptacles for receiving CO.sub.2 snow and allowing the same to harden therein to form the individual bodies during movement of the receptacles along the upper run before being discharged upon transition to the lower run. The apparatus includes a snow production chamber for producing CO.sub.2 snow, which is in communication with a discharge of the aggregated body production chamber and which comprises its own downstream outlet such that the CO.sub.2 snow acts to convey the individual bodies released from the discharge of the aggregated body production chamber and towards the target.
