CO2 Generators operate by burning carbonaceous fuels such as propane or natural gas. The burners used in Green Air Products CO2 generators are specifically designed to maximize the production of CO2 and minimize heat as a by-product. Through the use of a constant burning pilot and equipped with a safety valve to avoid the loss of fuel should the pilot light go out, Green Air Products generators provide CO2 far more economically than any other means of enrichment. The generators may be controlled with timers, are easily installed, dependable and efficient. Transformer included. Operates on 110 volt AC.
