Given the current coronavirus pandemic, we are in an unprecedented, exceptional situation. The current situation is changing our lives in all aspects and we face new challenges every day. People's health and protection are a top priority.
For this reason, the Government and companies are constantly looking for new ways to halt the global pandemic and to meet constantly changing conditions. WERMA Signaltechnik is making an important contribution to this: With the new CO2traffic light, the current carbon dioxide (CO2) concentration in the ambient air can be measured and made visible. The three traffic light colors clearly show whether ventilation is necessary or not.
This avoids high concentrations of CO2 and aerosols in the ambient air of any offices and conference rooms, restaurants, shops, theatres, doctor's practices, universities, gyms and all other public buildings and reduces the risk of transmission of COVID-19 to a minimum.
Green light indicates: Everything's OK!
An increased CO2concentration in the room can correlate with an increased bacterial concentration as well as increased infection and absence rates. In order to sustainably protect all persons staying indoors for a longer period of time from COVID-19 infection and other infectious diseases, it is necessary to ventilate regularly. Therefore, the Federal Environment Agency officially recommends ventilation from 1,000 ppm (ppm = parts per million, i.e. volume parts per million volume parts).
This is where WERMA's new CO2traffic light comes in: It continuously measures the current carbon dioxide concentration in the ambient air and shows precisely whether or when it is time for the next ventilation.
This is illustrated in a clear way with the help of the three common traffic light colors so that everyone easily understands:
The WERMA CO2 traffic light
WERMA's solution for CO2measurement in indoor air consists of a three-stage signal tower, which is immediately ready to use and very easy to install thanks to Plug & Play: Simply plug in the supplied power supply, wait until the self-calibration is completed and the traffic light is ready for use. The current CO2concentration in the ambient air is measured immediately and displayed using the three traffic light colors.
The traffic light is clear, easy to understand and does not require explanation. The signals are clearly visible from all sides thanks to the 360-degree illumination and the extremely bright LEDs guarantee that they are clearly visible even in direct sunlight and bright surroundings.
Ideally, the CO2 traffic light is placed in the middle of the room, i.e. not too close to the window and not higher than 2 meters from the floor. Since carbon dioxide is distributed fairly evenly throughout the room, a traffic light is sufficient for most rooms. Two traffic lights are recommended in larger conference rooms or sports halls.
High air quality - more important than ever
Thanks to WERMA's CO 2traffic lights, air quality in enclosed spaces can be improved in the long term, as high concentrations of carbon dioxide and aerosols in enclosed spaces are avoided through regular and effective ventilation. This not only achieves a more hygienic, but also more productivity-friendly and better indoor air. "We are delighted that the CO2traffic light is not a short-term investment for public buildings, offices and universities," says Manuel Schutzbach from WERMA Technical Sales. "Because a low CO2content in the room not only protects against infection, but also improves the concentration and performance of all those present."
Thanks to WERMA's new CO2traffic lights, this not only ensures the highest possible level of safety for employees, customers and visitors, but also promotes long-term productivity and performance.
