Carbon Dioxide (Co2) Generators
by Green Air Products
Green Air Carbon Dioxide Generators are unsurpassed in low cost CO2 generation. Available in both natural gas and liquid propane versions, Green Air CO2 Generators produce air fertilizing carbon dioxide for less than 20 percent the cost of bottled CO2. 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. A constant burning pilot is used to ignite the gas when the generator is turned on. A thermocouple is used to monitor the pilot flame. If the pilot flame is lost, a safety valve will close so that unburned fuel will not be released into the enclosure. CO2 Generator operations may be automatically functioned according to actual ambient values when installed in conjunction with the CDMC-2. This control device continually samples the level of carbon dioxide in the growing area and functions the generator whenever CO2 levels do not meet your predetermined values. Generators are easily installed, dependable and efficient. Transformer included. Operates on 110 VAC.
Heavy-duty anodized aluminum housing will withstand all types of elemental exposure to insure years of uninterrupted use. A wide variety of models ranging from the hobby level CD-3, which generates sufficient carbon dioxide levels to enrich 3,000 cubic feet of growing area, to the commercial sized CD-36, capable of generating increased carbon dioxide levels in greenhouses up to 20,000 cubic feet.
The chart below will give you minutes of operation required for areas and models shown. The top row of the chart represents the cubic feet of the area (Length x Width x Height) in the hobby greenhouse or growing enclosure. Left column is model size. Model numbers represent maximum CO2 output per hour in cubic feet (CD-3 = 3 cu feet per hour). As an example, a CD-6 will take 10 minutes to produce a carbon dioxide level of 1m000 parts per million (ppm) in a 1,000 cubic foot hobby greenhouse or other controlled environment garden.
Large greenhouses logically require longer charge times and as such, multiple units may be necessary for optimum results. The CD-36 takes 1.66 minutes per 1,000 cubic feet of area. Therefore a 20,000 cubic foot area would take 33.2 minutes (20 X 1.66 = 33.2) to charge to 1,000 ppm. For most applications, this may be an acceptable charge time. Ideally, the area should be enriched with carbon dioxide as quickly as possible for maximum advantage. Charging the atmosphere quickly insures that the rapid photosynthesis process will not be interrupted. For most applications, strive for a five to ten minute per hour charge time. Try not to exceed twenty minutes per hour when possible, although this is not always practical in very large spaces. Your microclimate will need to be recharged every one to four hours using a 24 hour timer, depending on how much atmosphere is lost due to natural convection or plant usage.

Each model includes all necessary connections including your choice of a natural gas or liquid propane regulator and 25 feet of hose that runs from the gas source to the generator.
