The heating system in greenhouses is fully automated and divided into 5000-6000 m2 sectors. Separately mounted heating collectors are installed on separate sectors. The heating system consists of floor heating circuit, a crop heating circuit and a top heating circuit. Boiler burners can run on natural gas, diesel fuel and fuel oil materials. In addition, CO2 generated from natural gas is used to feed plants. The CO2 supply system is also installed at the request of our client. To implement a CO2 system based on a greenhouse project, the installation of a hot water tank (buffer tank) is important. As a result of using this system, productivity increases by 10-15%.
