Recover initial costs within an average of 2 years. Achieve energy savings through the visualization of CO2 and automatic ventilation control! We also support pre-implementation effect verification.
The "CO2 Sensor Controller" measures and displays indoor CO2 concentration, temperature, and humidity, maintaining a comfortable indoor environment while enabling automatic ventilation control based on CO2 levels, which can reduce electricity costs (energy savings). It is an integrated system for measurement, display, and control, making it easy to install and maintain as an add-on. Ventilation is necessary for maintaining indoor comfort, but excessive ventilation can lead to increased air conditioning load. By implementing automatic ventilation control based on CO2 concentration, energy savings can be achieved. The CO2 Sensor Controller can be connected to various ventilation devices and supports ON/OFF, high/low, and airflow control operations. By providing information such as drawings, we can assist in creating installation plans and conducting simple calculations of energy-saving effects. 【Recommended for the following people!】 ■ Those in small to medium-sized facilities considering easy-to-implement energy savings ■ Those considering CO2 control in new buildings ■ Those interested in "visualizing" indoor environments 【Benefits of Implementation】 ■ Improvement of indoor environment (realization of a comfortable space) ■ Reduction of electricity costs (energy savings) *For more details, please refer to the PDF materials or feel free to contact us.
