Dennerle Magnetic Valve

The Dennerle CO2 solenoid valve is a valve for automatic CO2 control in combination with CO2 fertiliser systems in freshwater aquariums.

The solenoid valve can be screwed directly onto the CO2 valve. The solenoid valve operates extremely quietly, is energy-saving and has only a low heat development. Controlled by a timer, the de-energised, closed CO2 solenoid valve interrupts the CO2 supply and can thus save 50% of the CO2 consumption. Since plants do not consume CO2 at night, the solenoid valve should, therefore, run synchronously with the light control of the aquarium. In conjunction with a pH value control, the CO2 supply is optimised because the aquarium is dosed with exactly the amount of CO2 that is consumed.

With the Dennerle Solenoid Valve Pro, you can adjust the CO2 supply exactly to the needs of your plants and also save electricity and CO2!
