2. TECHNICAL CHARACTERISTICS
2.1 Introducon
Any occupied room requires the correct supply of fresh air and, at the same time, the control of the internal thermo-
hygrometric conditions, through the recovery of energy from the air extracted from the room, by means of static counter-
flow heat recoveries, the level of well-being of the occupants is guaranteed, both in summer and winter.
For buildings that require air changes and are not equipped with dedicated air conditioning systems, the installation of such
units allows the supply of primary air at controlled temperature without substantially changing the internal conditions in the
occupied spaces. These units also make it possible to guarantee support for the air conditioning system in the intermediate
seasons using free-cooling or free-heating modes.
These units, if installed on existing buildings, guarantee the energy requalification of the system through the management of
the air change without additional charges; in the case of new installations, instead, the air change is completely carried out
allowing to reduce the size of the main air conditioning system.
In the intermediate seasons the building will benefit from free or partially-generated cooling from these units, which during
the partial load phases allow the main system to operate with higher efficiency.
The units are available in 10 sizes, with nominal air flow rates from 1000 to 21500 m3/h.
The heat recovery units are available in H1 and H2 configurations with their CONTROL BASIC, CONTROL EVO COP, CONTROL
EVO CAV versions.
2.2 Structure
The structure of the units can be realized in two versions:
VERSION 1:
Profiles 50 x 50 mm in self-supporting extruded anodized aluminium, with mechanical strength requirements in accordance with
EN 1886: D1 (M). 50 mm thick double-walled sandwich type paneling with exterior in pre-painted RAL 9010 galvanized sheet steel
and interior in hot-dip galvanized sheet steel with interposed insulation made of polyurethane foam with a density of 40 kg/m3.
This structure has a seal class L1 while the thermal transmittance and the thermal bridge characteristic is class T3/TB4 according
to EN1886.
VERSION 2:
Thermal break profiles 60 x 60 mm in self-supporting extruded anodized aluminium, with mechanical strength requirements in
accordance with EN 1886: D1 (M). 63 mm thermal break sandwich-type double-walled sandwich type panels with exterior in
pre-painted RAL 9010 galvanized sheet steel and interior in hot-dip galvanized sheet steel with interposed insulation made of
polyurethane foam with a density of 40 kg/m3. This structure has a seal class L1 while the thermal transmittance and the thermal
bridge characteristic is class T2/TB2 according to EN1886.
Safety microswitches are applied to the inspection doors to allow internal access to the various compartments of the unit only when
the unit is completely switched off. The main access and inspection panels consist of inspection doors with perimeter hinges made
of non-corrosive polyamide and handles.
All units can be supplied in both monobloc and modular sections for on-site assembly when required.
The units are supplied as standard in a MONOBLOCK conguraon, in case of mul-secon units, they are
available in special execuon. Please contact the Company for further details.
2.3 Heat recovery
The units are equipped with an aluminium counter-flow heat exchanger used to transfer heat from the exhaust air to the
fresh air. The heat exchange takes place in counter-flow with efficiency higher than 80% in dry air. The spacing between
the fins is optimised in order to reduce air-side pressure drop and fan power consumption. In some conditions of low
outside air temperature and high humidity, the exchanger may start to frost. The units are equipped with a defrost
system required in case of very low ambient conditions. The defrost system can either be electric or by hot water. The
heat recovery is also equipped with an additional by-pass damper for the management of the free-cooling and free-
heating mode. The heat exchanger participates to the Eurovent Certification program and it is sized according to the
ECO Design specification.

13
EN
2.4 Air lters
ePM1 ≥ 50% (F7) rigid bag lters in fresh air. Both types of lters are mounted on slides equipped with gaskets to ensure eec-
ve sealing. Their posion, upstream of the internal components, also guarantees their protecon.
2.5 Fans
The units are equipped with high eciency plug-fan type fans with built-in brushless EC motor. In this way it is possible to
guarantee an accurate regulaon of the airow both in the supply and extract secon, ensuring that all regulatory requirements
such as SFP are met with. The airow rate of the fan is managed through the integrated electronic control system thus
ensuring, according to the needs of the system, that the correct operaon of the unit is maintained with consequent saving
of the energy absorbed by the unit.
The fans are xed to the frame by means of selfcentering brackets to ensure the correct distance between the impeller and
the nozzle, thus opmizing performance.
2.6 Test
Units are fully assembled and wired at the factory and subjected to a complete funconal test before shipment. They are
manufactured in compliance with the safety standard of the Machinery Direcve 2006/42/EC, the Low Voltage Direcve
2006/95/EC, and the Electromagnec Compability Direcve 2004/108/EC and therefore complies with the "Health and
safety requirements" prescribed. Units are provided with CE markings, cercate of conformity, user and maintenance
manual.
2.7 Packing
Units are supplied on thick wooden feet and wrapped in plasc lm to protect against impacts during transport and handling
on site.
3. VERSIONS
3.1 Version CONTROL BASIC
CONTROL BASIC: complete with air temperature sensors installed on the fresh air intake and on room return air. The control
allows to select, in stepless mode, the supply and return fan speeds and automacally manages the heat recovery by-pass
damper through the motorized On/O control, summer/winter seasonal change over, and programming for daily me zones.
An oponal hot water or cold water coil may also be managed, controlled by a 3-way modulang valve through the room
return air sensor.
The oponal electric post-heang coil is also managed in modulang mode (always via the room return air sensor). The

Water control valve
It consists of a kit including the 3-way valve for the control of the water ow, to be combined with the hot and/or cold water
coil, and its modulang electric actuator. Connecon and ng devices not included (to be arrange for by the installer).
Hot water coil (internal)
The hot water coil is manufactured with copper pipes thickness 0,4 mm and aluminium ns thickness 0,11 mm. The pipes are
mechanically expanded in the aluminium ns to increase the thermal exchange rate. On request, it is possible to install coils
with dierent capacies from the standard ones, when previously agreed with the factory.
Cold water coil (internal)
The coil is manufactured with copper pipes thickness 0,40 mm and aluminium ns thickness 0,11 mm. The pipes are
mechanically expanded in the aluminium ns to increase the thermal exchange rate. On request, it is possible to install coils
with thermal performances dierent from the standard ones, when previously agreed with the factory. The cooling coil
secon is supplied complete with condensate drain pan with water discharge.

EN
Anfreeze electric coil (external)
The anfreeze system consists of an electric coil installed on the fresh air inlet. It is supplied in a dedicated secon external
to the base unit to be xed using an installaon kit supplied with it.
Defrost system (internal)
The automac defrost system consists of a self-regulang electric coil in PWM mode of the input power, installed on the
return air intake. The system is controlled by a special temperature probe posioned on the exhaust air and guarantees a
considerable reducon of the input power compared to the tradional systems available on the market.
Electric re-heang coil (internal)
All units may be equipped with an internal re-heang electric coil, made up of armoured steel electric heaters, supplied
complete with PWM control system, safety thermostat already wired and installed on board.
Air damper with actuator
This is installed on board the unit and operate to exclude the fresh air intake and/or the room return air ow. This opon is
parcularly useful in areas with very cold winter temperatures, where it is necessary to avoid dangerous self-induced cold
air ows by the installaon itself, during the stand-by period of the unit, with the risk of freezing the water contained in the
water coils, if any. The damper is controlled by On/O actuator for the opening or the closing, or with return closing spring.
Sound aenuator on return / supply side (external)
The sound aenuator is supplied in a dedicated secon external to the base unit, with the same sizes and features of the main
unit, to be xed using an installaon kit supplied with it.
The sound aenuator baes are made of mineral wool, thickness 100/200 mm, density 90 kg/m3, protected by a fabric veil
that prevents any risk of fraying of the mineral wool even at high air velocies.
The mineral wool is contained in a galvanised frame with a galvanised steel microstretched retaining mesh.
The sound-absorbing material is class M0.
CO2 probe
CONTROL BASIC version units can be equipped with air quality CO2 probe. This accessory is installed and wired in the factory.
If it's installed on the return air duct it allows to determine the quanty of carbon dioxide present in the environment,
increasing the quanty of external air to dilute its content.
ATTENTION: The CO2 probe is not available in CONTROL EVO COP and CONTROL EVO CAV versions.

7. OPERATING MODE
7.1 Winter operang mode
The return air from the room, with a higher thermal
load than the fresh air, crosses the plate heat exchanger,
where it gives up part of its thermal load and cools
down before being exhausted. The fresh air, with
a lower thermal load than the return one from the
room, crosses the plate heat exchanger in the opposite
direction and heats up before the introduction into
the room. The modulation of the airflow rate, through
variation of the rotation speed of the EC fans, will allow
a precise control of the supply air temperature. During
winter operation, in particular working conditions with
low external temperatures, the heat exchanger could
be subject to the formation of surface frost with consequent loss of efficiency.
To prevent this from happening, the unit provides for the controlled management of an automatic defrosting cycle, obtained by
means of a self-regulated electric battery in PWM mode, installed on the room air intake. The system increases the temperature
of the exhaust air thus avoiding the risk of frost on the heat exchanger. The system is controlled by a specific temperature probe
positioned on the air outlet and guarantees a considerable reduction of the power absorbed by the unit, compared to the traditional
systems on the market.
7.2 Summer operang mode
The return air from the room, with a lower thermal load
than the fresh air, crosses the plate heat exchanger,
where it takes part of its thermal load and heats up
before being exhausted. The fresh air, with a higher
thermal load than the room air, crosses the plate heat
exchanger in the opposite direction and cools down
before the introduction into the room.
The modulation of the airflow rate, by varying the
rotation speed of the EC fans, will allow a precise control
of the supply air temperature.
7.3 Free-Cooling operang mode
When the outdoor air temperature is lower than the
temperature of the room to be air-conditioned and if the
latter requires cooling, the unit operates in Free-Cooling
mode by opening the By-Pass damper positioned on
the plate heat exchanger and thus allowing the entry of
outdoor air without heat recovery.
