We are selling CO2 monitors that can be used as a guideline for ventilation at a special price. There are three types available, including models for large spaces and those with data loggers. During the season when air conditioning is used, some people may close windows and stop ventilating. However, neglecting ventilation can lead to an increased risk of infectious diseases, as well as decreased concentration and drowsiness, which can affect work efficiency. Generally, it is said that a comfortable air quality guideline is below 1000 ppm. Please consider this opportunity. *For pricing, please inquire.

We have released a promotional video for our CO2 controller. It clearly summarizes the mechanism, energy-saving effects, and implementation results, so please take a look.

We are pleased to announce that Sugunami Musical Instruments Machida Store and Machida Jorna Store, which operate the Yamaha Music School, have introduced our products. Models introduced: CO2 Monitor/Marvel 003, CO2 Controller/NMA-PR-R The CO2 concentration is visualized, providing a guideline for ventilation and achieving a comfortable indoor environment. Additionally, the controller contributes to energy savings through proper ventilation control. We hope to continue assisting in creating spaces where music can be enjoyed in a comfortable environment.

We would like to introduce the remote monitoring and control cloud service for indoor environments, 'Marvel IoT,' provided by CHC System Co., Ltd. Through smartphones and PCs, you can remotely monitor the indoor environment of facilities (CO2 concentration, ozone concentration, odor level, temperature, humidity) and remotely control equipment such as ventilation systems. You can remotely monitor the indoor environment, including CO2 concentration and temperature and humidity, in facilities located far away. Based on the accumulated data, we also propose improvements to the indoor environment. Additionally, we will be exhibiting at "HVAC&R JAPAN 2022 (the 42nd Refrigeration, Air Conditioning, and Heating Exhibition)" held at Tokyo Big Sight from February 1 to 4, 2022.
