5.1. CHILLER CIRCUIT
SCROLL COMPRESSORS
High efficiency scroll-type hermetic compressors, as-
sembled on elastic antivibration supports, driven by a
2-pole electric motor with internal thermal protection.
of the electric heater casing included as standard. The
heater is automatically powered when the unit stops,
provided that the unit is kept under tension.
WATER SIDE HEAT EXCHANGER
Of the plate-type (AISI 316), externally insulated with
closed cell material to reduce thermal dispersion.
Fitted, as standard, with antifreeze heater.
5.1.1. WATER FEATURES
SOURCE SIDE HEAT EXCHANGER
Made with copper pipes and aluminium louvered fins
blocked by mechanical expansion of the pipes. Provi-
ded with protective grid.
DESUPERHEATER / TOTAL RECOVERY
Unit with (AISI 316) heat plate, insulated externally
with closed cell material to reduce heat loss.

and hygroscopic material, able to withhold impurities
and any traces of humidity present in the cooling
circuit.

Allows the passage of the refrigerant in just one
direction.
MECHANICAL THERMOSTATIC VALVE
The mechanical valve, with external equaliser positio-
ned at the evaporator inlet, modulates the flow of gas
to the evaporator, according to the heat load, in order
to ensure a correct heating level of the intake gas.
SOLENOID VALVE
The valve closes when the compressor turns off,
preventing the flow of refrigerant gas towards the
evaporator.
INDICATOR FOR LIQUID PASSAGE WITH HUMIDITY

Used to check the refrigerant gas load and the eventual
presence of humidity in the cooling circuit.

ELECTRICAL ACCESORIES
• AER485: RS-485 interface for supervision systems with
MODBUS protocol.
• AERWEB300
Accessory AERWEB allows remote control of a chiller
through a common PC and an ethernet connection over
a common browser; 4 versions available:
AERWEB300-6: Web server to monitor and remote con-
trol max. 6 units in RS485 network;
AERWEB300-18: Web server to monitor and remote con-
trol max. 18 units in RS485 network;
AERWEB300-6G: Web server to monitor and remote con-
trol max. 6 units in RS485 network with integrated GPRS
modem;
AERWEB300-18G: Web server to monitor and remote
control max. 18 units in RS485 network with integrated
GPRS modem;
• AER485P1: RS-485 interface for supervising systems with
MODBUS protocol.
• PGD1: Simplified remote panel. Allows control of basic
unit functions and alarm notification. Remote mounted
up to 500 m away with TWISTED PAIR SCREENED cable
and TCONN6J000.
• DCPX: Low ambient device for cooling operation below
10°C down to -10°C. The
• DRE: It allows the reduction of peak power necessary for
the machine during start-up phase.
Accessories can only be fitted in the factory.
• DUALCHILLER: Simplified control system to switch on and
off, and command, two chillers (using Aermec GR3 com-
mand) in a single system, as if they were a single unit.
• MULTICHILLER:
Control system to switch the individual chillers on and off,
and command them, in a system in which several units
are installed in parallel, always ensuring a constant delive-
ry to the evaporators.
• PGS: Daily/Weekly Programmer.
Allows you to programme two time bands per day (two
switch on/off cycles) and to have differentiated program-
ming for each day of the week.
• PRM1-PRM2 FACTORY FITTED ACCESSORY. It is a manual
pressure switch electrically wired in series with the exi-
sting automatic high pressure switch on the compressor
discharge pipe.
MECHANICAL ACCESSORIES
•AVX: Sprung anti-vibration supports. Select the AVX
model from the compatibility table.
•VT: Group of anti-vibration, to be installed under the
base.
• GP: Protection grille, protects the external coil from acci-
dental knocks.
For more information please contact us.
Versions with Total Recovery and Condensing Units
are equipped with GR3 electronics (standard remote panel)
All the other versions have pCO5 electronics
(remote panel available as accessory)

ATTENTION
If the unit is installed in particu-

providing for windbreak to avoid
malfunctioning.
The units, in standard configuration, are not suitable
for installation in salty environments. For functioning li-
mits, please refer to the diagrams below, valid for AHRI
standard conditions.
Wind breaks should be implemented if the unit is
installed in particularly windy areas, to prevent a
malfunction of the unit.

CITY "STANDARD VERSION"/ "HEAT
PUMP VERSION IN COOLING MODE"
The cooling capacity efficiency and electrical input
power in conditions differing from normal conditions
are obtained by multiplying the nominal values (Pf, Pa)
by the respective corrective co-efficients (Cf, Ca).
The following diagrams show how to obtain corrective
coefficients to use for units in their various versions
in cooling mode; external air temperature, to which
reference is made, is shown in correspondence to each
curve.
KEY:
Cf: Corrective coefficient of the
cooling capacity.
Ca: Corrective coefficient of the
input power.
