DESCRIPTION

The FE (L) model has been, thanks to our experience, built upoin the reliability and the success of the FE SYSTEM. In the applications of particular food-agricultural processes, we have been able to conceive and develop the FE (L) SYSTEMS range. This is a new range of active electrostatic filters with built-in electronics, specifically for oil and oily vapour applications. The FE (L) SYSTEM represents a revolutionary development, and a valid alternative to traditional filters. It was conceived to facilitate the use of electrostatic oil filters for specific filters as well as to facilitate the use of electrostatic oil filters for specific processes. Its use in agricultural-food plants, ensures consistent filtration efficiency. Thanks to high separation and oil accumulation capabilities, because of low load losses, it also provides important energy savings. Its multipole connection system means that several of these filters can be connected at the same time but this does, of course, depend on the air flow and filtration requirements. In addition, electrostatic filters can be installed and removed by simply sliding them across the equipment filter frame support. The built-in electronic power input circuit is equipped with LED to notify the user that the filter is working correctly. It is furthermore also available to a customized range of electrostatic filters (for oil and oily vapour applications) without built-in electronics.

CHARACTERISTICS

FE (L) filters are particularly suited for the abatement of polluting substances such as oily vapours and mists, with and without particulate matter. The main distinguishing characteristic of this filter is the botton section of the capture blades, the shape of which has been purposely conceived to enable the dripping of high quantities of oily pollutants, with reduced formation of electric discharges between the plates. In addition, the special mechanical construction ensures, also in the presence of emulsifying oils, that no electric discharges occur on the insulator, therefore providing high reliability in the long term. The open bottom part makes it possible to collect (in appropriately conceived containers) the condensation formed during the filtrationprocess. The high separation performance together with a high capability of capturing particulate, also makes it possible to obtain compact abatement systems with low load losses virtually consistent across time and with high levels of efficiency. It is therefore possible to obtain a reduction in electric consumption when compared with other systems using mechanical filters. From an operating point of view, the FE (L) 600 filter is capable of condensing hundreds of grams of oil every day and this filter is furthermore certified for the Ozone emissions, which is significantly lower than the maximum set by the legislation.

In the electrostatic filter the initial pressure drop increases only a small part while the filter gets dirty. This characteristic, combined with the extraordinary capacity of pollutants accumulation, allows the filter to have a long duration of use between one maintenance and the other. In a traditional rigid pocket filter the initial pressure drop is higher than in an electrostatic FE (L) filter and it increases considerably during its clogging. The bag must be replaced when it has reached the maximum pressure of 450 Pa. WHen we compare the FE (L) filter with two other different filtering systems operating at the same contaminated indoor air conditionsand at the same air flow capacity, we can observe that FE (L) filter has a pressure drop that grows very slowly, while in a F6 filter it reaches the max pressure drop of 450 Pa before the filter even is saturated. It means that maintenance is required to replace the filter F6. Even more evident is the durability of a filter F9 that need to nearly three substitutions in the same period of operation than a filter FE (L). A higher flow restriction means merely higher energy consumption for the pocket filters. Compared with an electrostatic filter FE (L), we can estimate a double energy consumption using an F6 and three times more using an F9.

COMPLETELY REGENERBLE

The electrostatic filter FE (L) is embedded with a rigid rugged aluminum frame which gets dirty by attracting and holding airborne particles of pollutants which remain accumulated on collector plates. When the filter is saturated, it can be easily washed with detergent and high pressure water to remove dirtiness and put it back as new. If the washing operations are done properly and carefully the filter can last for almost 15 years. The electronic circuit permts to generate the necessary voltage directly in the filter. Through the multipolar connectors PSC, JC, FCC, it is possible to carry the power supply to the filter with power voltage of 230V-50Hz, combine multiple filters in a row and give out alarm signal. Efficient watertight solutions allow the electronic box to be bathed with the filter during the maintenance instead of being removed.
