Autonomous air-cooled direct expansion air
conditioners, designed for installation on the
outside wall of the air conditioned room. They are
particularly suitable for air conditioning of prefabricated
buildings, shelters and containers. The
materials and construction of the units are
designed for installation outdoors.
The condenser is incorporated in the unit which
is pre-charged and tested in the factory.
Installation and connection to the power supply
can be done by non-specialised staff.
Units are designed to allow maintenance from
the outside only, without needing access to the
air conditioned room. All essential components,
including the condenser fan, can be inspected
and removed from the front of the unit. In multiple
installations the units can therefore be installed
side by side.
GENERAL DESCRIPTION
SELF-SUPPORTING CABINET in galvanised
steel complete with flange for fixing to the
external wall of the air conditioned room.
EXTERNAL PANELS in 1.2 mm steel painted
with epoxy powder and lined with scratchresistant
self-extinguishing sound absorbing
insulating material.
ANTI-TAMPER SCREWS to protect against
unauthorised access to the internal components
of the unit.
FILTER in self-extinguishing material with EU2
efficiency (Eurovent 4-5) fitted in rigid metal
cage.
Double inlet CENTRIFUGAL FAN(S) in
galvanised steel with forward-angled blades
keyed directly to the motor shaft.
The free cooling cycle consists of the introduction
into the environment of external air when this is
sufficiently cold to absorb the thermal load of the
environment.
The unit is fitted with a butterfly grille and two air
intakes:
• recycled air intake (on right hand diagram);
• external air intake (on left hand diagram);
A. NORMAL FUNCTIONING (Fig. a)
During normal functioning, the damper is
positioned to take in only air from the conditioned
environment (grey arrow on the right), closing the
external air intake.
The air taken in is sent by the fan towards the
cooling coil and then re-introduced into the

REFRIGERANT CIRCUIT including:
• filter and flow sight glass
• thermostatic expansion valve
• high- and low-pressure pressostats (with
manual reset)
mPW CONTROL MICROPROCESSORS; this
control, standard on version F, includes ambient,

environment. Cooling is via the cooling cycle
(starting the compressor) and commanded by the
thermostat.
B. FREE COOLING (Fig. b)
As soon as the external air is of a low enough
temperature to maintain the temperature in the
environment at the desired level, the damper
changes position, taking in and discharging into
the environment external air instead of recycled.
The discharging of air (obviously in the same
quantities as that taken in) is via a vent, opened
by the damper, between the recycled air intake
and the outside (see fig. B below left)
During free cooling function, the compressor is
off.

USER TERMINAL for the setting and
visualisation of unit function parameters
INTERNAL HUMIDITY SENSOR for activating
the dehumidification cycle.
CONDENSER FAN VARIABLE-SPEED
CONTROL with:
• thermostatic sensor for versions with freecooling
cycle and optional mPW
microprocessor control
• pressostatic sensor for all other versions, for
external temperatures down to -20°C.
HOT GAS RE-HEAT for controlling ambient
temperature during the de-humidification phase
with low sensible load without using the electrical
re-heat., thereby reducing installed power and
energy consumption. This device is not available
on size WM*0121.
INTAKE AND DISCHARGE GRILLE FOR
DISTRIBUTION OF AIR IN THE
ENVIRONMENT with two rows of slats.
FRESH AIR INTAKE with metal pre-filter and
grille to regulate the quantity of air intake
(included with free-cooling units).
BLOCKED FILTER ALARM SENSOR
consisting of a dirty filter control pressostat
ELECTRICAL POWER FACTOR
CORRECTION CONDENSERS for maintaining
the electrical power factor (cos. ϕ) over 0,9.
CLOCK BOARD for the management of time
and date events
RS422 SERIAL OUTPUT for the transmission of
data to a centralised supervision system
DOUBLE ELECTRICAL POWER SUPPLY for
normal function with mains power and
emergency UPS for the fan and the opening of
the external air vent.
C. MODULATED FUNCTION (fig. c)
When the external temperature falls further, the
introduction of 100% external air would cause
excessive cooling.
The control system therefore changes the
position of the damper to mix external and
recycled air to maintain the temperature in the
environment at the required level.
In any case, the temperature of the air taken in is
maintained above a pre-set minimum.
MINIMUM QUANTITY OF FRESH AIR
It is possible to pre-set a minimum opening
position on the damper to allow the taking in of a
proportion of fresh air in any operating mode.

I livelli di pressione sonora, eseguiti con un fonometro BRUEL & KIAER mod. 2235 - conforme alle norme IEC 651 classe II - con filtri d'ottava mod.
1625, sono riferiti a condizioni di campo aperto, senza l'effetto di riverberazioni ambientali.
Il livello sonoro ponderato A, espresso in dB(A), è ottenuto secondo la normativa ISO R 226-1961. L'indice NR è conforme alle curve di riferimento
secondo la normativa ISO R 1996-1971.
The noise pressure levels, measured with a phonometer BRUEL & KIAER mod. 2235 - according to IEC 651 norms, class II - fitted with octave filter
mod. 1625, refer to free field conditions, without the effect of ambient reverberation.
The A-weighted noise level, given in dB(A), is measured according to ISO R 226-1961 standard. The NR index complies with ISO R 1996-1971
standard.
