C.A.P. CO2 Generators 

Many greenhouses use CO2 generators to boost CO2 levels safely and economically. C.A.P. has developed some of the safest and most reliable CO2 Generators capable of producing between 3 and 26 cubic feet of CO2 per hour.

The GEN-1 is recommended for areas up to 15’ x 15’. The GEN-2 is recommended for larger areas up to 30’ x 30. Both feature a "two-stage" safety pilot valve, which will not allow fuel to flow to the burner unless the pilot is lit.

Both come with a standard "tip-over" switch will shut down the fuel to the main burner in the event the unit falls or tips over. The C.A.P. CO2 generators are constructed of powder coated steel enclosures that resist moisture, rust and discoloration.

Manufactured in the USA using AGA and/or UL listed components. Both models are expandable! This allows you to increase the unit`s capacity to produce CO2 simply by installing additional burners. Each burner adds approximately 3 cubic feet per hour.

C.A.P. GEN-1 comes standard with one burner, producing approximately 3 cubic feet per hour. You can add up to 3 additional burners, increasing capacity to approximately 13 cubic feet of CO2 per hour.

The GEN-2 comes standard with 5 burners, producing approximately 16 cubic feet of CO2 per hour. You can add up to 3 additional burners, increasing capacity to up to approximately 26 cubic feet of CO2 per hour.
