The heart of the CarboMaster unit is the patented CO2 Injector. This injector injects liquid into the gas in preference to the traditional method of injecting gas into liquid. This achieves faster dissolution and the CO2 is tightly bound to the beverage. The requirement for long pipe runs, low temperatures and high pressures is significantly reduced.

Furthermore the injector can be cleaned using standard CIP procedures as an integral part of the cycle. The rate of CO₂ addition can be monitored with a CO₂ measuring instrument. This can be used to control the dosing set-point, but the accuracy of the system is improved by the use of mass flow measurement for the gas. This gives a level of accuracy, which is better than the measuring instrument, typically +0.1 g/kg CO₂ in the beverage. The standard capacity range spans 5,000 - 70,000 l/h.
