Presentation of the unit
This new series of industrial chillers has been designed to meet the air conditioning requirements of
medium-large systems in the industrial, service and business sectors. Suitable for outdoor installation, they
are built for various types of system and to comply with the needs of highly qualified planning engineers.
The complete series for use in hydronic systems includes 8 sizes with refrigerating power ratings ranging
from 136 to 299 kW and heating output ratings ranging from 165 to 350 kW. When the units were desi-
gned, particular attention was also paid to sound emission in our endeavour to comply with the increasingly
more restrictive laws governing acoustic pollution: all the sizes are therefore available in both the basic and
silenced versions, to choose depending on the noise level required.
All the units can produce cold water at a temperature between 5 and 10C (summer operating mode) and
hot water from 35 to 55C (winter operating mode). As part of the standard supply, they are pre-enginee-
red for summer/winter operation at low/high outdoor air temperatures thanks to use of a condensation/eva-
poration monitoring system through continuous control of the fans by steps. All the units are equipped with
2 independent chilling circuits, each of which has two Scroll compressors. This allows the power genera-
ted by the unit to be modulated from 25% to 100%, thus adapting to the heat load of the system supplied.
All the units are equipped with a thermal barrier plate type evaporator protected by means of a differential
water pressure switch and electric antifreeze heater, coils with extended surfaces and extensive heat
exchanging areas formed by copper pipes and notched aluminium fins, electric fans with scythe-shaped
vanes to reduce the sound emission, electric panel for adjustments and controls, controller with micropro-
cessor.
The standard supply can also be integrated with a vast range of electrical and mechanical accessories. The
Water Storage Tank and Pumping Module with 1 or 2 Pumps are particularly important accessories. If both
are chosen, the tank is configured for storage on the delivery to the system or for storage on the return part of
the system, or for storage pre-engineered for the primary and secondary circuit, depending on the type of
Pumping Module selected.
The chillers have been designed for use with R407C environment-friendly refrigerant.
All the units are accurately built and tested individually. Installation only requires electrical and wet connections.

Hydraulic and chilling circuit components
13. 4-way cycle reversing valves. Reverse the direction in which the refrigerant flows when the operating mode changes
(Cooling mode or Heating mode).
14.Refrigerant safety valve. (Conforms to the Directive governing pressurized vessels -PED). Installed on the delivery pipe of
the compressors. It acts if critical service faults should occur.
15.Fluid cock -Gas cock. Allow all the refrigerant in the coils to be pumped and then stored so as to carry out servicing work
or to replace all the components of the chilling circuit without having to drain it.
16.Dehydrator filter. Of the removable cartridge type. Retains impurities and traces of moisture in the circuit.
17.Fluid and humidity indicator. Signals when fluid passes through the circuit, indicating that the refrigerant charge is correct.
The fluid indicator also changes colour to show the amount of moisture in the refrigerant.
18.Low pressure switch. With fixed setting. It is installed on the intake pipe and blocks the compressors of the circuit in que-
stion if the operating pressures drop below the tolerated values. It automatically resets as the pressure increases. If it activa-
tes frequently, the circuit in question will block and can only be restarted by resetting via
the user interface terminal.
19.High pressure switch. With fixed setting. It is installed on the delivery pipe and blocks both the compressors of the circuit if
the operating pressures exceed the tolerated values. If it activates, the circuit will block and can only be restarted by resetting
via the user interface terminal.
20.Electric resistors to heat the compressor oil. Belt type, one per compressor. They activate when the compressor turns
off. Their task is to keep the temperature of the oil sufficiently high so as to prevent refrigerant from migrating during these pau-
ses.
21.Fluid receiver. One per circuit. They are plenum tanks that account for the refrigerant charge variations required by the
machine as the operating modes change (Cooling mode or Heating mode).
22.Fluid separator. One per circuit, installed on the intake part of the compressors to protect against backwashing.
23.Fluid solenoid valve.One per circuit. They shut off when both the compressors of the circuit switch off, preventing liquid refri-
gerant from flowing towards the evaporator during periods at a standstill.
One-way valves. Make the refrigerant obligatorily pass through the appropriate heat exchangers, depending on the operating
cycle.
Thermostatic valve. With external equalizer.Its task is to supply the evaporator correctly, keeping the selected degree of super-
heat at a steady level.
High temperature thermostat. One per compressor, installed on the delivery pipe to protect the compressor if the end of com-
pression temperature exceeds 130° C.
Differential water pressure switch. This is standard supply and is installed on the connections between the exchangers water
inlet and outlet. It blocks the unit if it activates.
Pressure taps: 1/4 “ SAE (7/16” UNF) type with air pump. Allow the operating pressure of both the circuits to be measured in
3 main points: compressor delivery, flow-restricting component inlet, compressor intake.

Mechanical accessories
GM (M) Pressure gauge unit. Consisting of 4 pressure gauges that display the pressure of the refrigerant fluid on the intake and
delivery of the compressors of both circuits..
GP (M) Protective grilles. Consisting of metal grilles that protect the coils with extended surfaces.
AVM (F) Spring vibration dampers. Consisting of 4 spring vibration dampers to install under the unit. They reduce the mechani-
cal vibrations generated by the compressor and fans during their normal operation, and that are then transmitted to the bearing
surface of the machine. The insulation degree provided by the vibration dampers is about 90%.
SAA (M) Water storage tank. Made of adequately thick painted sheet metal, this reduces the number of compressor start-ups
and fluctuations in the temperature of the water conveyed to the users. It is insulated with thermal barrier material to prevent the
formation of condensation and heat exchanges towards the outside. The accessory is inclusive of water safety valve, air vent,
water drain and antifreeze heater connection. In conjunction with the Pumping Module accessory, it can be supplied in 3 different
configurations: Storage on the Delivery, Storage on the Return, Storage pre-engineered for the Primary and Secondary circuit.
Pumping module with 1 o 2 Pumps (The second pump, installed in parallel to the first, allows to have one workable
pump to use if the first doesn't work).:Besides the pumps, this accessory is equipped with all the hydraulic components (water
filter, expansion tank, on-off valves, water pressure gauge) required for complete installation and easy maintenance.
Different water accumulation tank configurations are therefore available in combination with the pumping module accessory:
MP-AM : Storage on the water supply plant Delivery(1):The pump draws water from the supply plant, sends it to the plate
type heat exchanger and then to the inertial storage tank. In this configuration, when the pump operates in its nominal condi-
tions, it is able to supply the circulating water with a residual head of about 140 to 220 kPa in the Cooling mode (from 13 to 20
m.w.c.) and from 80 to 150 kPa in the Heating mode (from 14 to 22 m.w.c).
MP-AR: Storage on the water supply plant Return(1):The pump draws water from the inertial storage tank, sends it to the plate
type heat exchanger and then to the system. In this configuration, when the pump operates in its nominal conditions, it is able to
supply the circulating water with a residual head of about 140 to 220 kPa in the Cooling mode (from 13 to 20 m.w.c.) and from
80 to 150 kPa in the Heating mode (from 8 to 22 m.w.c).
MP - PS: Storage pre-engineered for the primary and secondary circuit. The pumps sole task is to allow water to circulate
around the primary circuit: this circuit includes the storage tank and plate type heat exchanger (chillers water circuit). Assembly
of the pumping section for the secondary circuit is at the installers charge and includes the storage tank (with pre-engineered
wet connections) and the system to be supplied.
KT - Pipe kit, consists of two steel pipes insulated with heat barrier material. If the Pumping Module accessory is not installed,
the pipe kit is obligatory to be taken.

Electrical accessories
CR - Remote Control. This device consists of a remote control
which allows all the control and monitoring functions of the control
unit on the machine to be controlled up to 100 meters away from the
actual machine itself. It has been specially designed for installation
on a wall inside the building. Use a threepole. The transmission line
must be routed in a dedicated duct, separate from any electric
powering lines (230/400 V). It has four keys used to select the con-
trols on the controller installed on the machine, the only difference
being that the scroll-up and scroll-down functions have been sepa-
rated from the mode and on-off keys in order to make the control
easier to use.
During normal operation, the operating temperature (or the temperature read by the probe on the exchanger inlet) in
degrees centigrade appears on the LCD display or the alarm code, if at least one is activated. The temperatures read
by the other probes can be read by means of a few simple operations.
If faults occur during normal operation, the controller stops the machine and displays the code of the alarm in question.
After the alarm has been checked and its cause eliminated, the controller can be reset by pressing the on/off key.
The remote control has the following keys:
The controller has five LEDs on the left-hand side of the interface, that display the status functions of the machine:
•LED of compressors 1 and 2 (circuit 1).
•LED of compressors 3 and 4 (circuit 2).

SWL = Sound power levels, with reference to 1x10-12 W.
The Total sound power level in dB(A) measured in compliance
with ISO 9614 standards, is certified according to the Eurovent
certification program.
Eurovent certification (E) exclusively refers to the Total Sound
Power in db(A), which is therefore the only binding acoustic spe-
cification (the values of the Octave bands in the table are indicati-
ve).
SPL = Sound pressure levels, with reference to 2x10-5 Pa.
The sound pressure levels are values calculated by applying the
ISO-3744 relation (Eurovent 8/1) and refer to a distance of 1
meter away from the external surface of units operating in the
open field with directivity factor 2 and the units operating in nomi-
nal conditions in the cooling mode.

SWL = Sound power levels, with reference to 1x10-12 W.
The Total sound power level in dB(A) measured in compliance with
ISO 9614 standards, is certified according to the Eurovent certifi-
cation program.
Eurovent certification (E) exclusively refers to the Total Sound
Power in db(A), which is therefore the only binding acoustic speci-
fication (the values of the Octave bands in the table are indicative).
SPL = Sound pressure levels, with reference to 2x10-5 Pa.
The sound pressure levels are values calculated by applying the
ISO-3744 relation (Eurovent 8/1) and refer to a distance of 1
meter away from the external surface of units operating in the open
field with directivity factor 2 and the units operating in nominal con-
ditions in the cooling mode.

HOW TO SELECT THE UNIT
1) The Standard Performances tables in the Technical data and standard performances chapter give the
Useful output capacity in the cooling mode and Heating output in the heating mode values with the relative com-
pressor input power values of each unit in standard conditions. The data can be interpolated but not extrapola-
ted.
2) The Technical data and standard performancestables in this technical handbook refer to use of R407C refri-
gerant, as shown by the titles in the reference section and depending on the unit in question.
3) The tables under the Standard Performances values give the operating temperature limits of the outdoor air
that may enter the coils.
4) The power input values in the Standard Performances tables refer to the compressors alone. Consult the
Technical data of the unittables for the power input of the fans at their top rate.
5) The Standard Performances values refer to 5 C of ΔT of the water between the inlet and outlet of the plate-
type heat exchanger. Use correction values FcD given in Tab.3 for different values, in the case of operation in the
cooling mode. Corrective factor FcD is not considered in the heating mode as its influence is negligible. To ensu-
re the plate type heat exchanger operates in the correct way, comply with the limits to use given in the Loss of
head and Useful head sections.
6) The Standard performances values are based on a 0.44* x10 -4 m2C / W fouling factor of the heat exchanger
on the wet side. Use correction factor FcP indicated in Tab. 1 for different values.
7) The Standard Performances values refer to a unit installed in places at zero meters above sea level (Pb =
1013 mbar). Use Performances correction factor FcH indicated in Tab. 2 for operation at different altitudes.
8) The Standard Performances values in the case of operation in the heating mode refer to outdoor air with 87%
relative humidity. Use correction factor FcUr in tab. 4 for different values.
9) Consult the Loss of head section to determine the loss of head on the wet side through the heat exchanger. If
the units are equipped with the Pumping Module accessory with storage on the water supply plant delivery, the
useful head of the unit can be determined by means of the diagram in the Useful head section. Remember that
the curves refer to the useful head calculated as difference between the pump head and the loss of head of the
components (filter, on-off devices, pipes, tank, plate type heat exchanger) installed in the hydraulic circuit of the
unit.
10)Use the Noise levelstables to check the acoustics.
11)If the version with the Pumping Module accessory is being evaluated (standard type with storage on the delivery
or storage pre-engineered for the primary or secondary circuit), check the capacity of the surge chamber in the
system in the Maximum water volume section.
Example of how the unit is selected:
The unit must be able to supply an 160 kW capacity in the following conditions:
- Outdoor air temperature = 40C
- Temperature of the cold water outlet by the machine = 6C
- Inlet/outlet temperature difference of the water Δt = 5 C
- The unit must also be able to provide a 200 kW heating output, working in the following conditions:
- Outdoor air temperature = 5C
- Relative humidity of the outdoor air = 70%
- Temperature of the hot water outlet by the machine = 50 C
- Inlet/outlet temperature difference of the water Δt = 5 C
Also consider:
- a 0.88x10-4m2C/W fouling factor on the wet side of the heat exchanger
- unit installed in a place at 900 meters a.s.l.
Solution:
The reversible refrigerating power must first be chosen by selecting the machine that meets the required values
in the cooling mode and by then checking that the machine selected is able to provide the power required in the
heating mode.
Selection for operation in the cooling mode:
In view of the operating specifications required, a basic version of the unit can be chosen as there are no parti-
cular limitations concerning acoustic emission.

HOW TO SELECT THE UNIT
Beginning with the refrigerating power required by the given conditions of use and having checked the Standard
performancestable, model IP 205 VB AB 7M5 can be selected as it provides a standard refrigerating power of
(171.4 kW).
The effective refrigerating power provided by the machine in the real conditions of use will be:
Where: Pf= refrigerating power provided in the real operating conditions (kW)
Pf s = refrigerating power provided in standard conditions (kW)
FCH = correction factor for the height above sea level
FCP = correction factor for the fouling factor
FCD = correction factor for the temperature difference
The available data and tables 1, 2, 3 can be used to determine the values of correction factors FCH = 0.97, FCP =
0.98, FCD = 1, after which the refrigerating power supplied in the real operating conditions can be calculated, i.e.:
In the given conditions of use, the selected unit provides a 163 kW refrigerating power, which meets the cooling
requirements.
The flow rate of the water that passes through the evaporator will be:
with c = 4.186 kJ/kg C specific heat of the water.
A 27 kPa loss of head is given in the Loss of head graph, on a level with the determined water flow rate and the
curve of the selected model. This value is acceptable since it is within the limit values given in the Operating limits.
A 177 kPa useful head is given in the Useful head graph, on a level with the determined water flow rate and the
curve of the selected model.
Calculation of the maximum volume of water must also be used, as shown in the table of the maximum water volu-
me reference section, and the procedure for calculating the volume of the additional surge chamber adapted if
necessary (if the real volume of water in the system exceeds the maximum volume of the actual system itself).
Verification for operation in the heating mode:
With the data available for operation in the heating mode and considering the previously selected reversible unit IP
205 VB AB_7M2 , the standard heat output in the heating mode is Prs = 222.1 kW.
Considering the real conditions in which the machine is operated and using tables 1, 2, 4 (Tab.3 does not
apply in the heating mode), it is possible to calculate the values of corrective factors FCH =0.97, FCP=0.98,
FcUr =0.96 and, thus, the value of the heat output in the heating mode in the real conditions of use, i.e.:
As it exceeds requirements, this heat output value confirms that the selected unit is a valid choice: The flow rate of
the water that passes through the exchanger-evaporator will be:
which corresponds to a 41 kPa loss of head, thus within the limits of the exchanger.
A 144 kPa useful head is given in the Useful head graph, on a level with the determined water flow rate and the
curve of the selected model.
