PRODUCT DESCRIPTION
The TA is a compact thermoventilation unit designed to guarantee high static pressures in small or medium sized rooms. Suitable for both
vertical and horizontal installations, it is available in two versions: the rst features a hot or cooled water 4 or 6 rows copper-aluminium coil,
the second features a direct expansion copper-aluminium coil with R410A. The machine is equipped with high static pressure centrifugal fans,
double intake, forward blades and electric motor coupled directly to multiple speeds three of which are selectable. In addition, the unit, both
in vertical and horizontal conguration, is equipped with an inner and aluminium alloy isolated condensate drain tray. Wide range of remote
controls and accessories to meet dierent needs such as 1 and 2 rows post-heating coil, G4 air lter, ow and intake grid, mixing chamber, ow
anges with circular vents.
This unit is designed for a maximum amount of outdoor air of 10% of the total declared airow
Structure
Made in galvanised steel sandwich panels with 15 mm thick polyu-
rethane insulation (45 kg/m³ density). The intake and ow panels are
equipped with anges to couple to any air canals or to the accesso-
ries provided. Specic brackets supplied with the unit make it easier
to secure it to the wall.The galvanised steel condensation drip tray is
provided with a drain tting threaded on both sides and is suitable
both for horizontal and vertical installation of the unit.
Electric fan unit
This consists in high performance double intake centrifugal fans
with blades facing forwards. The electric motor is coupled directly to
the fans.
Heat exchange coil
Made of copper piping and aluminium louvers locked by the
mechanical expansion of the pipes.The threaded sleeves for the
hydraulic connections and the air bleeding valve are supplied.The
water heat exchanger coil is also available in direct expansion oper-
ating with R410A refrigerant uid. It is made with the same materials
of the water coil.
Air lter
Air is ltered by class G4 eciency 50 mm thick synthetic lters
(according to the EN 779 standard) positioned on the intake. The
lters are easily accessible for servicing and cleaning. For the VFR
accessory, ltering is carried out through F6 degree of ltration soft
bag lters. For higher degrees of ltration, please contact our Sales
Technical Department.

Below are the diagrams representing the different ways of coupling the
accessories to the base units. The selection of a intake/flow accessory
module precludes the choice of otheraccessories in the vertical direction
but not in the horizontal. For example: if the “SAS” accessory is provided
in intake, that accessory will not be compatible with the accessory “S2Z”
but it can be combined with the“SSL” and “FTP” accessory. The diagrams
respectively represent a horizontal and vertical configuration of the unit.
The diagrams may not be exhaustive of available combinations: however,
we recommend to follow the rules set-out and possibly contact the
AERMEC Sales Technical Dept.

VENTILATION CURVES
The following diagrams show the ow rate-useful static pressure curves (at vent) of the units, with 4-row coil and with a 0% clogging degree of
the G4 lter.
For units with dierent congurations or accessories, reduce the useful static pressure with the pressure drop values of the added components. The
values of these pressure drops can be found on the tables below the charts.
