The heating system of greenhouses is fully automated and divided into sectors (which can not be more than 5000 – 6000 m2 ). Each sector has a separate heating collector. The heating system consists of bottom plant and top heating for protecion during snow and frost. The boiler burners can work on gas, diesel fuel and oil. For additional fertilizing of plants with carbon dioxide Gas (CO2), at the request of the customer, a CO2 system is installed. Istalled Buffer tank with different dimensions is mounted outside the greenhouse. By using co2 system in greenhuses fertilization can be increased up to 10- 15%.
