CO2 emissions in the environment and the theory of global warming.

If emissions are not reduced according to the agreements of Kyoto Protocol, the threshold level will  be exceeded in around 2030. According to the most reliable forecasts, exceeding the threshold would increase the average  earth temperature by 2 ° C, raising the sea level at least one meter by 2040. Less likely studies, foresee a temperature increase up to 6 ° C with catastrophic consequences.

The people can notice the increase of extraordinary weather events in recent years.

Italian Legislative Decree 152/2006 indicates the implementation of all the most appropriate measures to reduce polluting emissions into the atmosphere, in order to achieve the objectives deriving from the Kyoto Protocol. CO2 is one of them!

CO2 emissions in the environment

The major pollution problems occur in the winter months and are due to civil and industrial heating, but he production departments of the mechanical industries are increasingly air-conditioned, in the summertime, too. The external expulsion by a centralized filtration system without the possibility of an internal recirculation makes  ineffective for environmental protection and extremely expensive. In fact, a filtration system with external expulsion generates a continuous air exchange, with heavily affects on heating/air conditioning costs and contrasts with the intentions proposed by the Kyoto Protocol.

Let’s take the amount of money, considering some dimensional typologies of mechanical companies. We are trying to evaluate the environmental impact of AR Filtrazioni purification systems in every aspect.

THE AIR PURIFIER SENSITIVE TO ENVIRONMENT PROBLEM

AR FILTRAZIONI oil mist collectors, with very high efficiency Hepa filters up to H13 according to the European Norm EN 1822 , have reached highest levels of purification, allowing the re-introduction of purified air inside the workshop. This important goal avoids the creation of fireplaces for external expulsion and guarantees low management costs, flexibility, safety, energy saving and environmental protection.

Some key results:

1 – Safety performances
Residual concentrations of pollutant outgoing from the air cleaner:
➢ Less than 0.05 mg / m3, 100 times lower than the Italian TLV limit and 10 times lower than the more restrictive TLV ACGIH limit (0.5 mg / m3);
Residual concentrations of pollutant in the workshop:
➢ Less than 0.2 mg / m3 (very often around 0.1 mg / m3). Obtained with dozens of working machine tools and in the winter months.
Equal and often improved result if compared with suction systems with external expulsion of the filtered air!

2 – Economic savings:
➢ re-condensation and recovery of the oil directly in the machine tool for reuse (even 6/7 liters per day for an average of € 3 liter).
We have to consider that the oil expelled into the atmosphere settles on the roofs and at the first rain it is washed and transported to the aquifers creating further damage.
➢ with the re-introduction of the purified air inside the work environment without expelling outside, the customer is NOT required to build any chimney and the annual analysis of emissions.

3 – Benefits in terms of savings on heating/air conditioning costs:
➢ Recycling heated air in winter and conditioned in summer is a source of significant energy savings, which translates into an annual Savings of € 415.00 per single air cleaner, with 1700 mc / H air flow rate.

4 – Performance in terms of environmental protection: 
➢ Zero exhaust emissions; 
➢ The savings on heating/air conditioning allows reduction of:
– 1.96 kg CO2 emissions of CO2 for each cubic meter of methane burned to heat the expelled air;
– 0.53 kg of CO2 for each kWh consumed for the refrigeration, which results in a containment of CO2 emissions of 9,000 kg per year, for each plant installed.

The calculations were carried out considering one shift, for 2 or 3 working shifts the values ​​increase proportionally.

For example: In Italy, each kWh of electricity generates 0.53 kg of CO2 (ENEL sources).
