Unit description
This new series of industrial chillers has been designed to meet the demands of global markets in the small-medium power indu-
strial and commercial plants. Units are compact and highly configurable, built to fit different types of plants so to meet the needs
of highly qualified engineers.
Units are water chillers condensed in air with axial fans suitable for outdoor installation: the structure and panels are robust, made
of galvanized and painted steel; all fasteners are made of stainless steel or galvanized steel, the frame containing the electrical
equipment and all the components exposed to weather have a minimum IP54 degree of protection.
This series is composed of twelve models divided in four sizes with nominal cooling capacity from 53.5 to 200 kW.
The units product cold water from 5 to 25°C and as standard they are equipped with continuous adjustment of axial fans rota-
ting speed in order to allow the units to operate with low outdoor temperature in cooling mode as well as to reduce noise emis-
sions.
All the units are equipped with 2 scroll compressors arranged in pairs (tandem) on 1 circuit operating with environmental
friendly R410A gas, brazed plate heat exchanger completely insulated and protected by water side with a differential pressure
control and with an antifreeze electrical heater, coil heat exchanger made of louver aluminum fins and copper tubes, axial fans
with profiled blades to contain noise and with thermal protection built-in, on-board electrical control panel equipped with control
system to manage the main functions.
During the design of the units particular attention has been given to achieve high system efficiency, to reduce overall energy con-
sumptions and sound levels in order to meet the increasingly restrictive laws in terms of noise. Upon request, you can choose
for a Standard Unit (AB) or Low noise unit (AS) which provides sound attenuation thanks to sound absorbing insulation in com-
pressors area, sound jackets on compressors and reduced speed axial fans, or a Extra low noise unit (AX), which provides in
addition slower axial fans and more powerful finned coils.
All units are accurately build in compliance with the existing standards and are individually tested in factory. Only electrical and
hydraulic connections are required for installation.

unit includes: a soundproofing jacket for the compressors, an acoustic cladding around the compartment where they are hou-
sed, to reduce noise level, and reduced rotating speed of axial fans; AX unit integrates batteries with condensing surface increa-
sed and rotating speed of axial fans further reduced. All units are equipped with two compressors connected in parallel (1 sin-
gle cooling circuit) which can operate at the same time (100% cooling power) or individually (50% of the cooling power), thus
adapting to the different thermal loads of the system supplied.

Hydraulic and cooling circuit components
8. Safety valve. Installed on the delivery pipe of the compressors, this operates if extreme faults should occur in the plant.
9. Fluid tap. Ball type, this allows the gas flow on the fluid line to be turned on and off. Along with the tap on the compressor
delivery, it allows the components of the fluid line to be subjected to extraordinary maintenance work and the compressors to be
replaced if necessary (without discharging the coolant from the unit).
10. Compressor delivery tap. Ball type, allows the gas delivered to the compressors to be turned on and off.
11. Dehydrator filter. Mechanical type. Retains impurities and traces of moisture in the circuit. Hermetic type for models 50÷80;
cartridge type for models 90÷200.
12. Fluid and humidity indicator. Signals when fluid passes through the circuit, indicating that the coolant charge is correct.
The fluid indicator light also indicates the amount of moisture in the coolant by changing colour.
13. High pressure switch (n°2). With fixed setting. Are is installed on the delivery pipe and blocks the compressors if the ope-
rating pressures exceed the tolerated values. If it activates, the unit will block and can only be restarted by resetting via the user
interface terminal.
14. Water differential pressure switch. This is standard supply and is installed on the connections between the water inlet and
outlet of the exchanger. It stops the unit if it activates.
15. Pressure taps: 1/4 " SAE (7/16" UNF) type with flow regulator. Allow the operating pressure of the system to be mea-
sured: compressor delivery, lamination component inlet, compressor intake.
16. Pressure taps: 5/16 " SAE type with flow regulator. Allow the charge/discharge of the gas from the system, precisely from
compressor outlet an expansion valve inlet.
17. Electrical heating elements to heat the compressor oil. "Belt" type. These activate when the compressor turns off and
keep the temperature of the oil sufficiently high so as to prevent coolant from migrating during these pauses.
- Low pressure switch (N°1). With fixed setting. It is installed on the suction pipe and blocks the compressors if the operating
pressures drop below the tolerated values. Automatically resets as the pressure increases. If it activates frequently, the unit will
block and can only be restarted by resetting via the user interface terminal.
- Thermostatic valve. With external equalizer, this supplies the evaporator correctly, keeping the selected overheating degree
at a steady level.

NOISE LEVELS
The noise levels refer to units operating in the nominal conditions (water temperature: inlet:
12°C - outlet: 7°C, Outdoor air temperature 35°C), due to a change of external air tempe-
rature noise levels may change to ensure proper functioning of the unit within operating
range.
The acoustic pressure levels are calculated 1/ 5 / 10 meters away from the outer surface of
the unit operating in the free field and resting on a reflecting surface (directional factor of 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 and it is the only mandatory value
(the values of octave band 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 (Q=2) and the units operating in nominal
conditions in the cooling mode.
