Portuguese The interest in CO2 enrichment has risen and declined several times throughout this century. During the last few years this interest has strongly increased, mainly due to a better scientific understanding of how CO2 affects plants and due to the introduction of non-polluting CO2 sources.
Importance of CO2 Enrichment
CO2 enrichment decreases the oxygen inhibition of photosynthesis and increases the net photosynthesis in plants. This is the basis for increased growth rates caused by CO2 at low as well as at high light levels. Elevated CO2 concentrations also increase the optimal temperature for growth.
With the right condensing boiler system in place, a BioTherm CO2 System can easily be integrated to achieve elevated CO2 levels in the greenhouse environment.

CO2 Enrichment Systems
Centralized C02 Distribution
CO2 levels are naturally low in a greenhouse environment as plants use available CO2 as part of the photosynthetic process.
Increasing CO2 levels above ambient conditions promote increased plant growth and health. With the right condensing boiler system in place, a BioTherm CO2 System can easily be integrated to achieve elevated CO2 levels in the greenhouse or indoor growing environment.
BioTherm systems pull CO2directly from the boiler’s exhaust gases and distribute them uniformly into the growing environment while ensuring other harmful gases are kept at a safe level.
With a BioTherm CO2 System, there is no need for large bulk tanks or individual CO2 burners. These systems can be used in indoor and greenhouse operations.
