Indoor CO2 sensor that supports efficient ventilation indoors.
CWL (Wall-mounted type) CDL (Duct-mounted type)
Approximately 30% reduction in cooling load achieved! Measuring indoor CO2 concentration and enhancing heating and cooling effectiveness through ventilation control!
This product accurately measures the indoor CO2 concentration. By utilizing this data for ventilation control, it maximizes the effectiveness of heating and cooling. It detects changes in concentration according to fluctuations in the number of people indoors, preventing excessive intake of outside air. There has been a record of approximately 30% reduction in cooling load! 【Features】 - Accurately detects indoor CO2 concentration! - Combines with ventilation control devices to enhance heating and cooling effectiveness! - Demonstrates significant energy-saving effects! - Maintenance-free for long periods due to patented self-calibration function. *For more detailed specifications, please download the catalog or contact us directly. ★We are currently seeking sales agents.
