Carbon dioxide generators operate by burning carbonaceous fuels such as propane or natural gas. The burners used in Green Air Products CO2 generators are specially designed to maximize the production of CO2 and minimize heat as a by-product. Green Air Products generators provide CO2 far more economically than any other means of enrichment. Carbon dioxide enrichment equipment and methods have improved as experience and the understanding of atmospheric control and plant physiology have advanced. Plant metabolism and growth rate are dependent on the available atmospheric CO2. Plants are keenly sensitive to CO2 variations; optimum values must be constant and precisely controlled. The method, timing, and size of equipment must be properly determined to provide maximum benefits and economy. Carefully follow the operation charts to choose the proper size generator for the cubic foot area. Keep the recharge times to a minimum for best results. Do not undersize the generator or optimum results may never be achieved. Operates on 110 VAC.
