Carbon Dioxide Transmitter, Monitor and Controller

Carbon dioxide (CO2) is the second main gas responsible of the greenhouse effect and the major gas discussed during environmental summits. It is mainly used, according to its state:

• Under its solid state, carbon dioxide (CO2) is used as a cool pack.
• Under its gaseous state, it is used in the beer brewing and the wine growing
• Under its liquid state, carbonic gas is used to charge efficient extinguishers against any type of fire.

It is the result of complete combustions, both natural (volcanic eruptions, fire, etc.) and anthropogenic (car engine combustion, industry combustions, etc.)

Naturally present in the atmosphere at low concentration, carbon dioxide (CO2), also known as carbonic gas, remains hazardous. As it is essential for photosynthesis, it can be found in greenhouses to increase plant growth.

EFFECTS OF CARBON DIOXIDE ON HEALTH

FEATURES OF CARBON DIOXIDE

The carbonic gas is colourless in the visible light but absorbing in the infrared spectrum, and such is responsible of the greenhouse effect.

Odourless, non-flammable and non-toxic, carbon dioxide (CO2) is produced in the body and eliminated in the lungs.

Nevertheless, the carbonic gas features asphyxiating properties. As it is heavier than the air it is present in the poor ventilated locations (confined spaces) like tanks, sewers, holes…

GasAlarm CO2 GAS DETECTOR

Fixed gas detection systems are able to measure the carbon dioxide variations.

• GasAlarm CO2 gas detector like the GAS-CO2-XXX allows percentage by volume measurements of the carbonic gas variations in the atmosphere.
• To monitor an area where several people work together like maintenance works in confined spaces.
• The fixed GasAlarm CO2 gas detection systems come with the following features:

Importance of CO2 Measurment Inside Metting Rooms, Classrooms, Offices etc

CO2 has been a hot topic for a number of years mainly in relation to climate change and government policy. Leaving all of that aside, monitoring and controlling indoor levels of CO2 is important for everyone to consider for health, safety and even energy efficiency.

CO2 is a known indoor pollutant affecting performance in the workplace, at school, and even at the gym. Extreme levels of CO2 can lead to death, particularly in enclosed spaces such as laboratories, some hospital rooms, and breweries. CO2 can have a number of effects on home and workplace health and safety.

Controlling CO2 can also improve building energy efficiency, saving costs by up to 80%, and is even considered in the scoring of Green Star Ratings in building design.

Here, we outline reasons why you should be measuring carbon dioxide levels inside buildings.

1.      CO2 can kill you
Outside air has a CO2 concentration around 400ppm and each human breath contains around 30,000ppm. CO2 concentrations greater than 20,000ppm cause panting; above 100,000ppm (10%) CO2 can cause tremors and loss of consciousness; and values above 250,000ppm (25%) can lead to death. CO2 can be hazardous in one of two ways: by displacing oxygen in the blood or acting as a toxin.

2.      CO2 can decrease productivity
In the office and classroom, elevated levels of CO2, in the range between 1,000ppm and 2,500ppm, have been found to decrease information utilisation, increase headaches, decrease performance, and increase rates of absenteeism. Generally, CO2 concentrations at 1,000ppm can lead to a statistically significant decrement in decision making performance. CO2 concentrations at 2,500ppm, on the other hand, lead to large and highly significant decrements in decision making performance.

Although CO2 is not the only factor, elevated levels can lead to that feeling of lethargy and tiredness often associated with office workers. Studies have shown that performance, associated with lethargy induced by elevated CO2, can decrease by up to 10% for adults and over 20% for schoolchildren.

3.      CO2 can increase rapidly in poorly ventilated rooms
Figure 1 shows how rapidly levels of CO2 can increase in a poorly ventilated office. For example, in a 3.5-by-4-metre sized office with a single occupant, CO2 increased from 500 ppm to over 1,000 ppm within 45 minutes of ventilation cessation.

 

 Generally, where large numbers of people gather then CO2 will increase rapidly and lead to poor indoor air quality and pollution. In offices, this could be meeting rooms where a number of staff gather for extended periods in confined spaces.

Other places, such as gyms, shopping centres, cafes with soft drink vending machines, or libraries, are increasingly being recognised as indoor environments with elevated CO2 leading to poorer performance.

4.      Some locations have naturally high CO2 levels and need to be monitored
There are certain locations where indoor CO2 in an enclosed room or area can potentially reach extreme and life threatening levels.

Any enclosed or poorly ventilated location where CO2 cylinders are stored or used will potentially have harmful levels of atmospheric CO2. Examples of such locations include laboratories and hospitals.

Other spaces where CO2 is regularly used in the manufacturing or work process are also potential areas of harmful levels of CO2. Breweries are potentially extremely hazardous. Pockets of high CO2 can form in tanks and cellars and can quickly lead to death. Even bars, clubs and pubs, where CO2 cylinders are stored in a room, are increasingly required to monitor CO2 levels for workplace safety.

Using CO2 sensors for ventilation control can assist in these cases. However, other systems with audible and visual alarms, such as the  can be installed (Figure 2) warning workers and occupants of dangerous levels of CO2. The sensor is installed in the space with the CO2 source and an alarm indicator is placed outside.

5.      The novelty factor
Measure indoor levels of CO2 is new to most people. In fact, most people would not have a clue what the CO2 levels in their room are, what they should be, and how they change throughout the day with various factors.

Monitoring CO2 levels with a data logger is interesting, or having a wall-mounted or desktop LCD read-out, showing real-time CO2 levels, is also interesting. Informing your guests that you are controlling the ventilation in your building with a CO2 detector will certainly raise a few eyebrows!

In conclusion, a work or learning place designed for optimal productivity leads to better performance and, ultimately, is better for the bottom line. Monitoring and controlling CO2 levels is one approach to a healthier workplace environment by using cutting edge MSR Germany CO2 sensor range detectors.

Monitoring CO2 in Breweries

CO2 is extremely hazardous as it is completely odourless and colourless and there is no physical indication of danger until it is usually too late.CO2 is a hazard throughout the brewing process, right through to packaging and bottling because as it is heavier than air, it collects at the bottom of containers and confined spaces such as tanks and cellars and can even spill out of fermenting tanks and sink to the brewery floor, where it forms deadly, invisible pockets. To avoid the hazards associated with CO2, Monitoring CO2 in Breweries is quite essential.

The majority of Carbon Dioxide gas in beverage industry is used during carbonating process. It is also used in fermentation and refrigeration.

During the bottling process a high volume of Carbon Dioxide can be emitted into the plant room. Also during transport or storage of Carbon Dioxide, there is always a risk of unnoticed gas leakage. Exposure to elevated levels of CO2 can cause headaches, drowsiness or even sudden death. Hence facilities where there is a possibility of Carbon Dioxide reaching to the dangerous level, an accurate and reliable CO2 control system should be installed to maintain a healthy work-place.

Carbon Dioxide is also released during fermentation process. To achieve and maintain high operational safety the level of CO2 should be controlled in fermentation rooms by continuously monitoring CO2 Breweries fermentation rooms.

At ALVI we offer innovative sensors and controllers to identify and immediately display the life threatening CO2 gas. These products are based on years of experience and were compiled with a lot of know-how and tailored to individual customer application.

Gas Alarm Indoor/Outdoor Ambient Air Quality Monitoring Sensor PM 2.5/P.M10

ALVI – India (http://www.alviautomation.com)  in association with Gas Alarm Systems – Australia (http://www.gasalarm.co.au) take pride to offer Gas Alarm Indoor/Outdoor Ambient Air Quality Monitoring Sensor PM 2.5/P.M10

Particulate matter (PM) is a particle pollution, which is produced in a great number of ways that can be classified into either mechanical or chemical processes. Traditionally, the environmental sciences have divided particles into two main groups PM10 and PM2.5. PM10 is particles between 2.5 and 10 microns (micrometers) in diameter (a human hair is about 60 micron in diameter). PM2.5 is particles smaller than 2.5 microns. PM2.5 and PM10 have different material compositions and can come from different places. The smaller the particle the longer it can remain suspended in the air before settling. PM2.5 can stay in the air from hours to weeks and travel very long distances because it is smaller and lighter.
