A CO2 solenoid is an electromagnetic device that controls the flow of carbon dioxide in a closed system. It consists of a solenoid and a solenoid valve and is used in applications involving photosynthesis. The solenoid converts electrical energy into mechanical energy, releasing a certain amount of gas based on a timer or sensor. It is unnecessary in applications that require a constant level of CO2.
A carbon dioxide (CO2) solenoid is an electromagnetic device that functions as a switch to control the shutoff and flow of carbon dioxide in a closed system. It is a small but crucial component that is used with devices that release a controlled amount of carbon dioxide into places such as garden rooms, chambers or tanks. A CO2 solenoid commonly consists of two parts: a solenoid and a solenoid valve.
The first solenoid was invented by a French physicist named Andre-Marie Ampere in the 19th century. Since then, the apparatus has become more sophisticated in its construction, accuracy and applications. There are many other types of solenoids that all have a general relationship to their function, such as open frame solenoids, self-locking solenoids, tubular solenoids, and various sizes of push-pull solenoids. A push-pull solenoid works much like the CO19 solenoid. This is preferable for CO2 solenoids because they can take up less space and still have enough force to control varying amounts of carbon dioxide release.
Within the CO2 solenoid, the role of the solenoid is to convert electrical energy into mechanical energy and the role of the solenoid valve is to use that energy to release the flow of gas from one part of a closed system to another. In horticulture, a certain amount of carbon dioxide is transferred from the CO2 tanks, through the regulator, through the CO2 solenoid and then into the garden area.
At one end, the solenoids are connected to a timer or carbon dioxide sensor that tells it when to release a certain amount of gas. The timer sends an electrical impulse to a spring inside the solenoid which controls the flow of gas to the solenoid valve. The pulse acts as a command to create an opening between the regulator and the solenoid, which is at the other end. This allows a certain amount of CO2 to be released from the system. The exact amount of gas that is released is controlled by the regulator that the CO2 solenoid is connected to.
CO2 solenoids are most frequently used in applications involving photosynthesis. In applications that do not involve photosynthesis and require a constant level of carbon dioxide, a CO2 solenoid is unnecessary because a regulator alone will control CO2 levels. CO2 solenoids are needed in plant applications because plants use varying amounts of carbon dioxide throughout the day. Therefore, a CO2 solenoid with a built-in sensor will know how much CO2 an aquarium or greenhouse needs based on the consumption of the plants. This feature also prevents the wastage of carbon dioxide within a contained area.
