Green Air CO2 Generators 

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 generators provide CO2 far more economically than any other means of enrichment. A thermocouple monitors the pilot flame. If the pilot flame is lost, a safety valve closes so that unburned fuel will not be released into the enclosure.

Operations may run automatically when installed in conjunction with the CDMC. The CDMC continually samples the level of carbon dioxide in the growing area and functions the generator whenever CO2 levels do not meet your predetermined values.

The method, timing, and size of equipment must be properly determined to provide maximum benefits and economy. Do not undersize the generator or optimum results may never be achieved.

Green Air CO2 generators are easily installed, dependable and efficient. Transformer included. Operates on 110 VAC.
