Close air-conditioning means not only compliance with the severest environmental
parameters but also with the specific requirements of the site, such as EFFICIENCY,
FLEXIBILITY, OPERATING RELIABILITY AND RESPECT FOR THE ENVIRONMENT,
which today’s products must satisfy. ACCURATE has been created to meet all these
requirements, exploiting the renowned capacity to supply total quality airconditioning systems
EFFICIENCY
MOST OF ALL
COOLING?
SENSIBLE!
Nowadays efficiency is no longer considered as just energy
saving in respect of the single unit, but takes into account
both the PERFORMANCE of the whole system and its
COMPLETE RELIABILITY and MODULARITY over the years.
As is known, electronic equipment develops solely SENSIBLE
heat loads and therefore needs dedicated air conditioning to
deal with this.
In offering ACCURATE as a solution to technological cooling
problems, we have been concentrated on the use of known
quality parts and integration with BMS (building management
systems).
Standard solutions
- SCROLL compressors
- Thermostat valve with internal pressure equalisation
- Electronic thermostat (optional)
- Standard centrifugal fans
- High efficiency EC INVERTER ventilation (optional)
- Standard condensation control (DX versions)
- Electric reheat or with hot water
- Immersed electrode humidifying system
- Intelligent dehumidifying system with
constant airflow
- Semi-graphic control display
- Connection to traditional BMS
That is why ACCURATE has been made; to ensure maximum
SENSIBLE cooling capacity to the detriment of the LATENT
capacity, which would be a sheer waste of energy in these
applications.
This is of basic importance for transforming all the supplied
energy into a real room temperature control.
The result is a high SHR, minimum of 0.9 and a maximum of
1, in order to have the utmost SENSIBLE and not latent type
of cooling.

Cooling Capacity (kW)
It is a known fact that the set loads (W/m2) in
technological applications are continuously increasing.
This is mainly due to the increase in data traffic, giving rise
to new equipment with an increasingly greater capacity of
transmission, which in turn develops a higher heat load to
be dispersed.
kW / m2
This requires ever better performance from the airconditioning system that should, however, take up as little
space as possible, leaving it for the transmission
equipment.

Total versatility
All-round flexibility seen as a service offered for any type of system.
ACCURATE comes with capacities from 7 to 100 kW in the direct expansion version
with air cooling (AXO-AXU) and water cooling (AWO-AWU), from 7 to 221 kW in the
TYPES OF COOLING
AXO/AXU
DIRECT EXPANSION AIR COOLED
Refrigerant for heat transfer is used in these direct expansion units. The air in the room is
therefore treated in the evaporating coil containing the refrigerant.
The condensation heat is dispersed to a fresh air condenser that comes in the standard
supply with speed control to optimise the condensation pressure even in adverse temperature
conditions.
AWO/AWU
DIRECT EXPANSION WATER COOLED
Refrigerant for heat transfer is used in these direct expansion units. The air in the room is
therefore treated in the evaporating coil containing the refrigerant. The condensation heat is
dispersed in an internal plate-type exchanger connected in turn to a water circuit. The water of
condensation may come from a well, local water mains or closed circuits such as cooling towers
or dry coolers.
NB: for negative External T values antifreeze fluids must be used to protect the system
ACO/ACU
CHILLED WATER
Water coming generally from a chiller is used in these units to transfer the heat.
The flow of liquid through the unit water coil is controlled through an internal 2 or 3-way valve.
NB: for negative External T values antifreeze fluids must be used to protect the system
AIRFLOW CONFIGURATION
OVER
The versions called OVER with air
outflow from the top generally have
the air intake at the front, rear or
bottom of the unit, according to
customer choice, and the outflow
from the top is along ducts behind
suspended ceilings or front delivery
plenums.

RESPECT FOR THE ENVIROMENT
ACCURATE is totally in line with the known policy of full respect
for the environment in which we live and for human health and
safety. The use of recyclable materials and eco-compatible
refrigerants (R407C - R410A) to current standards and
legislation, make ACCURATE a state-of-the-art product in this
sense.
NOISELESS COLD
Modern telephone applications in residential areas must satisfy
increasingly severer requirements in terms of noise pollution.
ACCURATE then propose a large range to satify such requests,
often customized base on customer requests and site
conditions.
Main systems are:
-
MAINTENANCE
The design of the new ACCURATE models was based on the
need to simplify routine and extraordinary maintenance work
carried out during the lifetime of the product.
The refrigerant circuit area is completely separate from the fan
area, thereby allowing routine maintenance to be carried out also
with the unit in operation.
All servicing operations, even the most critical ones, can be
accomplished by a full front access.
That is why all the front panels are openable and can even be
removed thanks to simple hinges.

UNIT DESCRIPTION
Ductable close control air-conditioners with capacities ranging from 7 to 90 kW for vertical installation and cooling only, with
optional heating by means of heating element or hot water, optional humidifier and dehumidifier for precise temperature and
humidity control.
Particularly suitable for air-conditioning technological, server and CED rooms and all technological applications in general.
Units fitted with centrifugal fans with airflow from the top & from bottom and built-in water-cooled condenser.
External dry cooler.
Power supply 400/3N/50 (all models).
STANDARD UNIT COMPOSITION
Unit for installing inside or outside the room to be
air-conditioned.
Maximum resistance to rust thanks to galvanised sheet
metal structures and panels with powder-coated paint
finish. The panels are lined with sound-insulating material.
The microprocessor controls the compressor activation
times with FIFO logic, thereby regulating the cooling
capacity; it also controls the operating alarms with the
possibility of interfacing to supervisor and remoteservicing systems.
The reliability and functionality of the compressor and all
the other components are guaranteed by partners who are
world leaders in their sector.
Electrical box under IEC 204-1/EN60204-1 rules.
Double-inlet centrifugal fan units, directly coupled and
suspended on vibration-isolation mountings.
The fans are of the forward-bladed type for maximum
efficiency and low noise.
Condensation control for maximum low noise
(standard).
16
Standard G4 filtering section, F5-F8 optional, under
CEN-EN 779 rule with the separation degree 90,1%
ASHRAE. The filter is autoestinguishing type.
Refrigerant circuit consisting in the standard version of a
thermostat with external valve for internal pressure relief,
solenoid valve, high/low pressure safety pressure switch,
liquid indicator light and dehydrating filter.
