Hot water heating system

Hot water is produced in a central boiler and is usually pumped through the greenhouse. An advantage of the hot water system is that if the boiler fails, the hot water in the hotwater storage andpipes acts as a heat reservoir for a period of time. The systems include water delivery pipes, heat exchangers and circulation pumps for each cycle, electrical valves, railway heating pipes.

Hot air generator

In these types of heaters, the fuel is combusted in a fuel box, and the hot exhaust is passed through thin-walled metal tubes (heat exchangers). Heat is transferred to the metal, and the exhaust is removed from the greenhouse through an exhaust stack. The hot air may be blown directly into the greenhouse or forced through a polyethylene tube (jet tube) that runs the length of the greenhouse. These systems may use kerosene, liquid propane, or natural gas as a fuel source. The system is designed to reach the ΔΤ required by the crop. This method of circulating the air assures: Uniform temperature throughout the greenhouse

CO units

Carbon dioxide (CO2) is an essential component of photosynthesis (also called carbon assimilation). CO2 increases productivity through improved plant growth and vigor, expressed in earlier flowering, higher fruit yields, reduced abscission, and improved stem strength and flower size. CO2 distribution depends mainly on air movement within the greenhouse. When a single source of CO2 is used for a large surface area or several connecting greenhouses, it is recommended to install a distribution system for even distribution of CO2 , especially when flue gas CO2 or liquid CO2 is used. Air circulation using horizontal airflow fans or fan-jet systems provide uniform distribution by moving large volumes of air within the greenhouse when top vents are closed or exhaust fans are not operational.

Air recirculation fans

Air recirculation are used to move the air in the greenhouse, disperse humidity and spread heat evenly.

Sulfur evaporators

Sulfur evaporators are an effective method for controlling powdery mildew in the greenhouse. It is recommended to use sulfur evaporators as a preventative   measure.
