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 carbon dioxide sources.
Importance of CO2 Enrichment
Increased CO2 concentration decreases the oxygen inhibition of photosynthesis and increases the net photosynthesis in plants. This is the basis for increased growth rates caused by carbon dioxide 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 greenhouse CO2 enrichment 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 carbon dioxide 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 grow room CO2 enrichment system can easily be integrated to achieve elevated carbon dioxide levels in the environment.
BioTherm systems pull carbon dioxide directly 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 enrichment system, there is no need for large bulk tanks or individual carbon dioxide burners. These systems can be used in indoor and greenhouse operations.
