RETROFIT: AIR QUALITY AND SUSTAINABLE COMFORT

The market for Air Handling Units (AHUs) and Rooftops is growing significantly, supported by more demanding requirements as per Laws and Regulations.

The efficiency of the components used inside the ventilation systems is improving although there are still immeasurable opportunities to make the AHU system more efficient in its entirety; opportunities that depend on the choice of fans, cooling and heating devices, humidifiers, shutters and in particular filters.

The use of obsolete filter media involves, year after year, a considerable waste of money, requires major maintenance and produces high emissions.

What does retrofit mean and why is it important to do so?

RETROFIT means adding new technologies or functionalities to an existing ventilation system; by extending its useful life, improving its quality and efficiency from an energy (energy requalification) and pollutants’ reduction point of view.

The reasons for which a plant should be subjected to RETROFIT are therefore manifold.

To choose the FE/FEL SYSTEM active electrostatic filters produced by Expansion Electronic, designed specifically to be implemented inside air handling systems, corresponds to considerably simplifying the upgrade of existing ventilation units.

RETROFIT becomes simple thanks to the standard dimensions of the electronic filters (according to the EN15805 standard) equal to those of the mechanical filters. This means that no structural changes to the system are needed.

The active electrostatic filters having been patented with built-in electronics, completely waterproof, can be installed in series through simple connectors. This significantly reduces the complexity and time spent on wiring and electrical connections which can be done without difficulty by an electrician.

It should be emphasized that an old ventilation system generates high operating costs due to an obsolete filtration technology which, in order to maintain its filtration capacities high, requires the replacement of the filter media at least 3 times a year as reported by the regulations in force (UNI EN ISO16890).
This is because, during operation, standard filtration systems considerably reduce their filtration capacity and as they become saturated, the pressure drops increase. High pressure drops translate into high energy consumption.

Proceeding with the RETROFIT by implementing the active electrostatic filters of Expansion Electronic allows to increase the efficiency of the systems up to ePM1 95% (depending on the air crossing speed on the filters and the characteristics of the ventilation unit) and, at the same time, to reduce energy consumption up to 30% per year in medium ventilation systems.

Furthermore, the active electronic filters being made of 100% aluminum, a regenerable and recyclable material, guarantee a significant reduction in the management and maintenance costs of the units. In fact, they require a simple cleaning with water and detergent and do not need to be replaced. Their life is equal to that of the systems in which they are installed.
The RETROFIT of the standard filtration systems with the active electronic filters of Expansion Electronic is increasingly requested by customers operating in different sectors, as the FE/FEL SYSTEM filters are highly adaptable and compatible with countless applications.

Advantages of RETROFIT with Expansion Electronic FE/FEL SYSTEM active electrostatic filters:

  1.  Certified filtration efficiency, high and constant over time
  2.  High and constant hygienic and antibacterial effect
  3.  Very low and constant pressure drops over time
  4.  Reduction of management costs (filter that can be regenerated by washing with water and detergent)
  5.  No replacement required
  6.  Energy consumption reduction up tu 30% per year
  7.  Long life cycle (equal to the machine itself)
  8.  Replacement of standard filtration systems simplified thanks to EN 15805 / ASHRAE standard dimensions
  9.  Easy installation thanks to built-in electronics and multipolar connection
  10.  Made of 100% aluminum (recyclable material)
  11.  Sustainable filtration
  12.  Respect for the environment due to the total reduction of plastic and other materials that are difficult to dispose of
  13.  Preservation of the planet for future generations
