1- General characteristics and nominal output
The T series is the viable alternative to air handling units in the 3000 - 20000 m3/h
capacity range, when filtering, cooling and/or heating applications only are required in
civilian or industrial installations.
T series units can be integrated into a ducting system, and can be fitted with a various
types of delivery and return accessories.
Units can be installed horizontally or vertically, with air delivery and intake in several
directions.

5- Enclosure
The unit enclosure comprises a frame with insulating panels.
The sandwich type panels are composed as follows:
- outer wall: plastic coated galvanised sheet metal, powder blue colour;
- internal wall: galvanised sheet metal;
- insulation: polyurethane foam;
- total panel thickness: 25 mm;
- delivery plenum with sound absorbent lining.
The aluminium alloy frame (with natural aluminium finish) features black nylon corner
joints.
Panels are fixed to the frame by means of self-tapping screws with nickel washers.
6- Modularity and orientation

- Fan section.
- Containment section for heating coil and filter.
- Containment section for cooling coil, condensate collection tray and filter.

-Heating coil section + fan section + delivery plenum
-Return plenum + heating coil section + fan section
-Return plenum + heating coil section + fan section + delivery plenum
Cooling only or heating/cooling with twin-application coil:
-Cooling coil section + fan section
-Cooling coil section + fan section + delivery plenum
-Return plenum + cooling coil section + fan section
-Return plenum + cooling coil section + fan section + delivery plenum
Cooling e post-heating:
-Cooling coil section + heating coil section + fan section
-Cooling coil section + heating coil section + fan section + delivery plenum
-Return plenum + cooling coil section + heating coil section + fan section
-Return plenum + cooling coil section + heating coil section + fan section + delivery
plenum.

6.2 Orientations
The fan and cooling sections of the unit have been designed to allow selection of orientation by simply
switching the position of the intake panel and the air passage partition between the two sections. The coils
may be turned for connection on left or right side, as desired. The connection side is the one when facing the
unit with the fan motor on the left: The connection side is left when connectors are on the same side of the
motor.
All possible configurations with the two different orientations are shown below.
When defining the code, orientation refers to the unit without delivery and return plenums; account
also for the intake side of the first coil in the direction of air flow. For example, in the case of a unit
comprising heating coil, cooling coil and fan section, orientation will be defined by choosing between those
shown for fancoil units (see following pages).
N.B. Units in which the heating section is the first component must not be placed directly on the floor surface
when vertically oriented (1xx e 2xx).

7- Fans and motors
Fans
Centrifugal twin-intake fans with forward curved blades.
Sizes 6 and 7 are equipped with twin fans.
Motors
Motors are UNELMEC standard (protection category IP 55, insulation class F).
Transmissions
Fixed (on fan) and variable (on motor) Taper-Lock pulley and vee belts type SPZ or SPA
(depending on unit size).
Anti-vibration mounts
Elastomer anti-vibration mounts beneath motor-fan cradle and on upper side of fan. Fan
outlet makes seal with the panel by means of an elastic gasket.
8- Filters
Units are fitted with class G3 corrugated synthetic filters.
The filters are mounted on guides both in the cooling coil and the heating coil sections. In
the case of units complete with cooling and post-heating sections, filters are fitted in the
first section only.
Filters are removed by sliding them laterally through the opening on the connection side
panel by means of the tool supplied.
For quantity and dimensions of installed filter cells, refer to the technical specifications
table.

13- USEFUL PRESSURE FOR DUCTED UNITS
The graphs below show the useful external pressure supplied by the fan at max.
(continuous line) and min. (broken line) speed permitted by the variable pulley, according
to capacity, of the configurations listed in decreasing order of useful static pressure:
A : filter + 2 row heat exchange coil
B : filter + 3 row heat exchange coil
C : filter + 4 row heat exchange coil
D : filter + 6 row heat exchange coil
E : filter + 6 + 3 row heat exchange coils
Example:
Unit: T 1
Capacity: 2800 m3/h
Components: filter + 6 row coil
The point of intersection between a capacity of 2800 m3/h with continuous curve D (motor pulley completely
closed) and with broken curve D (motor pulley completely open) gives the value of useful pressure:
Maximum useful static pressure: 133 Pa
Minimum useful static pressure: 10 Pa

15- Heat exchange coils
Design:
- frames 1-2-3-4-5 : P2519
- frames 6-7: P6030.
Version
- Copper-aluminium
Type:
- water
Access:
Lateral removal after removal of screws securing coil to unit frame.
N.B. To invert the heating coil section and connections, simply rotate the entire section.
Condensate collection trays:
Made of peraluman with side drain.
Rows:
Coils are available with 2, 3, 4 and 6 rows.
Heating and cooling coils are identical, and may be housed in the cooling section (2-3-4-6
rows) or the heating section (2-3-4 rows).
Output:
