GENERAL SPECIFICATIONS
Presentation of the unit
This new series of industrial chillers and heat pumps has been designed to meet the demands of global markets in the small medium
power industrial 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 (IR) and heat pumps (IW, IP) water cooled, suitable for indoor installation;
if equipped with painted structure and panels (option) they are suitable for outdoor installation too. This series is composed of 11
models and two sizes with nominal cooling capacity from 70 to 240 kW and thermal capacity from 78 to 268 kW.
The heat pump units can be supplied for commutation between "COOL- HEAT" obtained by managing the hydraulic circuit (IW
units) or reversible on refrigerant side (IP units): the IP unit, compared with the IW unit, allows a reduction of installation space, a
simplification of the hydraulic circuit so achieving a cheaper and quicker installation. The units produce cold water from 5 to 20°C (in
cooling mode) and hot water from 25 to 55°C (in heating mode).
The units can be supplied for brine production (BR, BW, BP) that allow brine production from -10 to 5°C.
The development of the unit has mainly based on the selection of heat exchanger to obtain high efficiency at full and partial load. To
increase the seasonal efficiency index (ESEER) and so further containing power input and operation cost the units can be supplied
with electronic expansion valve (as standard for IP and BP units).
These features allow a compressors working with low compression ratios so increasing the reliability level and the operation life.
Great attention has been dedicated to achieve low 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) or Extra low noise unit (AX), The low noise unit (AS)
provides sound attenuation thanks to panels with sound absorbing insulation. The extra low noise unit (AX) provides a further sound
attenuation thanks to panels with sound absorbing and acoustic jackets for compressors.
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 exchangers (depending on unit type completely insulated and protected on water side with a differential
pressure control), electrical panel complete with electronic controller and display, phase presence and sequence control device (as
standard).
The basic unit (AB) is an essential structure made by sheet metal with anti-corrosion treatment (not painted) and without any closing
panels so suitable ONLY for indoor installation. As option the unit can be selected with painted structure (epoxy powders RAL 7035).
For low noise (AS) and extra low noise (AX) units, the painting is extended to all closing panels, so ensuring for the electrical panel
a protection degree IP54 and the maximun protection against adverse weather conditions: with this features the unit is suitable for
outdoor installation. A variety of other accessories are available to extend the capabilities of the units. Among various the unit can
be equipped with Pumping Module (MP) with 1 or 2 pumps with Standard (STD), High (HP1) and very High (HP2) available head.
This module- full integrated inside the unit- can be asked for the water circulation on the plant echanger, and/or for the water circulation
on the source echanger. So it is possible to order units equipped with maximum 4 pumps: max 2 for plant side, max 2 for source side.
The modules are equipped with all components necessary for a correct and easy installation so reducing the installation, space and
cost for hydraulic connections.
Note that with this accessory the total length of the unit increases (see the section “dimensional data”).
The electronic controller is able to manage different condensing control systems as modulating valves (2 or 3 way, available as
accessory too) or pumps driven by inverter.
Note that IW/BW units can be equipped with pumping module complete of electrical panel, but the controller is not able to manage
the pumps for the 2 operation modes (cooling and heating).
The units can be coupled with dry coolers, cooling towers, geothermal probes, or uses as cooling water city water, well-water, lakewater, etc.
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.

NOISE LEVEL
The noise levels refer to units operating in the nominal conditions (water temperature: inlet:
12°C - outlet: 7°C, Condenser water temperature: inlet: 30°C - outlet: 35°C).
The acoustic pressure levels are measured 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).
Open field
Q=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,
which is therefore the only binding acoustic specification (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 (Q=2) and the units operating in nominal
conditions in the cooling mode.

WATER PRESSURE DROP
Applications with city water, well water
Note for the calculation of pressure drop for the Source heat exchanger using city water or well water
Unit IR
Cooling Mode
The water entering to the Source heat exchanger is at a temperature usually in the range 10.15°C. The water entering to the
exchanger is controlled by a 2 way valve /ex accessory VDV) or a pump driven by inverter to have a leaving water temperature in
the range 30:40°C (ΔT water in the range 15 : 20°C) : so the water flow rate is roughly 1/3 ¼ of the source water flow rate in nominal
condition.
To get the pressure drop of the source heat exchanger use the diagram of this section (Source Heat Exchanger with well water)

To get the pressure drop of the source heat exchanger use the diagram of this section (Source Heat Exchanger with well water)
Heating Mode
The water entering to the Source heat exchanger is at a temperature usually in the range 8.15°C. In this case to achieve water leaving
temperature between 4 and 10°C (not dangerous for exchanger freezing) the water flow rate has to ensure a DT between 4 and 8°C:
so the water flow rate is roughly the same as in nominal condition.
To get the pressure drop of the source heat exchanger use the diagram Source Heat Exchanger with Tower Water
