GENERAL SPECIFICATIONS

The available special versions are described below:

VB: Standard unit.
VD: Version with Desuperheater (available forboth IR units and IP units)

Produces cold water in the same way as the standard version plus hot water from 30 to 70°C at the same time. This is achieved by installing a

water-refrigerant gas heat exchanger between the compressor and coils in order to recover 20 to 25% of the heating capacity that would otherwise
be dispersed in the air.
It helps to remind that hot water production is possible only in combination with cold-hot water production in the main heat exchanger and it is
subordinated by it.

VR: Total Heat Recovery version
Produces cold water as in the standard version plus hot water at a temperature of 35 to 55°C at the same time. This is achieved thanks to a water-

refrigerant gas heat exchanger that totally recovers the heating capacity that would otherwise be dispersed in the air. The total heat recovery
function is enabled and disabled by means of a valve on the compressor delivery of each circuit: when the temperature of the water that enters
the recuperator drops, the valve switches the hot gas flow from the condensing coils to the recovery heat exchanger. On the other hand, when the
temperature of the water reaches the set-point, the valve shuts off the heat recuperator and switches the hot gas flow to the condensing coils.
It helps to remind that hot water production is possible only in combination with cold water production in the main heat exchanger and it is subor­dinated by it.

versions and set-ups.

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 medium-big
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 and heat pumps 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 seven models divided in 6 sizes with nominal cooling capacity from 351 to 625 kW and thermal capacity
from 370 to 658 kW.

The units product cold water from 5 to 25°C (in summer) and hot water from 30 to 55°C (in winter) and as optional they are equipped

with continuous adjustment of axial fans rotating speed in order to allow the units to operate both with low outdoor temperature in

cooling mode and with high outdoor temperature in heating mode as well as to reduce noise emissions.
All the units are equipped with 5/6 scroll compressors arranged in tandem/trio on 2 circuits 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, electronic expansion valve, 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.
Hydronic group (MP) composed of fittings and connections is available as an accessory with 1 or 2 pumps and also with high

available head pumps; the accessory Water Storage Tank (SAA) is completely insulated and available on delivery side or for primary-

secondary hydraulic circuit (Victaulic connections already in place) depending on the kind of plants to serve.
A variety of other accessories are available to extend the capabilities of the units.
During the design of the units particular attention has been given to achieve high system efficiency, to reduce overall energy
consumptions 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) a Low Noise Unit (AS) which provides sound attenuation thanks to sound absorbing insulation in compressors

area, sound jackets on compressors, a head pressure control to reduce axial fans speed or an Extra Low Noise Unit (AX), which

provides in addition slower axial fans, more powerful finned coils and activation logic of the compressors in saturation.
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.

Tw= Outlet water temperature °C kWf = Cooling capacity (kW). kWa = Compressor power input (kW)
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at
nominal or maximum speed. A 0.44 x 10-4 m2 K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).

The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).

(1) : at these temperatures the fans are at maximum speed.
(2) : ATC (Advanced Temperature Control) function may occur.
