4 - TECHNICAL SPECIFICATIONS
4.9 OPTIONS
4.9.1 PRE and post-heating electric coil - PRE-DX
The electric heater contains a filament-type element, which limits pressure drop. Safety thermostats and control relay
are included.
The
PRE-DX pre-heater is installed inside the unit in fresh air stream , after the filter and performs a pre-heating of
the outdoor air when the fresh air temperature is less than a sattable value (default -5°C). This arrangement ensures
the maximum humidity efficiency, avoiding frost on the exhaust air stream.
The technical characteristics are shown in the following table.

4.9.2 Purifying system - BIOX-DX
The BIOX-DX technology is constituted by a special condenser made by a cylinder of quartz and by special metallic
net and it is feeded by a monophase alternate tension, low power consumption.
The electric field generated among the particular plate of the condenser,
gives place to the “liberation” of little negative
ions of oxigen and of positive ions, which easily unit as “cluster” or molecular ions, characterized by elevated oxidizing
power.
The constant use of the BIOX-DX device guarantees a considerable improvement of the quality of the air in indoor
places, like this: chemical composition, bacterial activity, electrostatic balance, assence of fine dusts and
unpleasant smells, with positive consequences in rooms for the health and the well-being of people.
Benefits for people:
• reduction of infection risks caused by bacterial proliferation
• improvement of the function and reduction of the dis eases of
the respiratory system
• reduction of anxiety, stress, sleepiness and intolerance of rooms.
Benefits for rooms:
• elimination of moulds which damage ceilings, walls and corners not much aired
• elimination of smells without the use of chemical products dangerous for health
• drastic reduction of mites
• elimination of electrostatic charge
With the BIOX-DX system , the indoor air is constantly healthy and deodorized as required by EEC regulation in
force concerning safety and health.
The system is installed inside the unit, before the supply fan (see picture 3). It starts to work when fans are
switched on; the maximum power consumption is 40W.
