The MiniGEN is a propane fueled CO2 generator that comes with a removable heat exchanger that allows you to use the MiniGEN with or without water cooling. Designed for use in small gardens (10′ x 10′ or less), the unit measures only 6″ x 7″ x 10″ and can be easily installed by wall mounting or by chain hanging. The 1,250 BTU/hr burner is operated by an electronic ignition with no standing pilot light. The unit has an anti-tip sensor and uses 12 volts to operate the ignition. The MiniGEN can be used with any CO2 monitor on the market, but when paired with the Hydro Innovations brand CO2 monitor, the result is a very safe, very cool, and very affordable alternative to CO2 bottles.
