Certificates
Certifications guarantee yields and product performance and are a tool that drives companies to reliable and high-quality choices. To guarantee what said before and to demonstrate once again the reliability and the excellence of Expansion Electronic’s products, our active electrostatic filters were tested by independent and international authorities such as for example the Hygiene Institute of Air ILH of Berlin, Polytechnic of Turin and the Technical Research Institute SP of Sweden. These authorities released the following certifications:
-

RETROFIT FOR THE COMFORT AND ENERGETIC PERFORMANCE IMPROVEMENT
The retrofit action aims to improve the current condition, both in terms of energy performance and comfort, of the existing conditioning or ventilation plants with the consequence to have a new qualification of the building.
Retrofit operations, especially in the civil sector, predict the electrostatic filter’s application that ensure very high energy efficiency thanks to their technology construction, the increased filtration efficiency and the reduction of management cost. Usually the FE SYSTEM electrostatic precipitators are installed in AHUs or Rooftops.
Finally, thanks to the material with which were built (aluminium), the filters can be easily regenerate through a simple washing process and its life cycle is about 15/20 years.
Plants characteristics with Electrostatic precipitators (electrostatic filters):
• high efficiency, on the top of E class filtration according to EN 1822 (E10 - E11) till to 2 m/s of speed velocity on the electronic filter;
• low costant pressure drop, compared to the pocket filters currently in use;
• maximum performance linearity (efficiency, pressure drop) during the operative life;
• maximum extension of the operative life (high load capacity in terms of weight of retained pollutants).
These are the basic features, to which is added an extremely important plus: an efficient antifungal and antibacterial action, in order to avoid the proliferation of bacteria colonies and molds in certain favourable conditions of temperature and humidity, often encountered in typical treatment plants air. For these reasons, and in order to reduce environmental impact, Expansion Electronic has implemented a retrofit’s action that allows you to replace the normal mechanical filters with those of new electrostatic generation one.
The advantages are mainly two:
- The lower energy consumption, “energy saving” given by the lower pressure drop and then the re-sizing of existing ventilation fan systems. Thanks to this action is guaranteed a good reduction in CO2 emissions.
- A considerable reduction of the amount of non-recyclable material.
RETURN ON INVESTMENT
The active electrostatic filter is an high-precision filter, composed by noble materials and it is not designated to a “disposable” use. The higher initial cost will be amortized over time (around 2 years) due to:
• Lower energy consumption with an elevate Indoor Air Quality.
• Lower maintenance costs;
• No cost for the replacement of the filter.
We calculated the return of investment taking into account the two different filtration technologies, electrostatic filter and mechanical.
We used the international formula developed by Eurovent for the electric power (Kw/h). During the evaluation of the cost is easy to understand that there is a significant investment for using electrostatic filters than the mechanics one, but this investment is offset by the large energy savings resulting in lower cost of electricity and with consequently less maintenance costs/replacement of filters. Mechanical filters must be replaced at least three times per year and this means a big economic expenditure.
The range of FE SYSTEM electronic filters generates a saving on energy costs equal to 30%. Reliability and performance of Expansion Electronic filters ensure low operating costs throughout the entire life of the plant. We can guarantee a quick return on investment estimated at about 2 years.
APPLICATION FIELDS
the new range of electronic air filters FE SYSTEM, could be installed in:
- air handling units (electrostatic filter for AHU);
- rooftop (electrostatic filter for Rooftop);
- ventilation ducts.
