PRODUCT DESCRIPTION
Air-cooled outdoor chiller designed to meet air conditioning needs in residential/
commercial complexes or industrial applications.
They are outdoor units with axial fan scroll compressors, microchannel batteries
and plate exchangers.
In the unit with desuperheater, it is also possible to produce free-hot water.
The base, the structure and the panels are made of galvanized steel treated with
polyester paint RAL 9003.
ACOUSTIC EFFICIENCY
This product range does not consider the energy class as the only selection param-
eter. Chillers can be chosen between different noise levels that do not affect the
energy class but maintain the best energy efficiency status.
The different versions have been designed to identify the unit according to the in-
tended use of the system.
The NRB range excludes any compromise in technological choices, as efficiency and
silence can coexist perfectly.
MAXIMUM ADAPTABILITY
To obtain a solution that allows you to save money and to facilitate installation.
These units can be configured with an integrated hydronic system.
The kit contains the main hydraulic components, and is available in various con-
figurations with a single pump or a standby pump and with various heads. (see
configurator)
EXTENDED OPERATING RANGE
This range can work at full load with outdoor temperature up to + 50°C. This occurs
in the high efficiency versions and also, for example, in versions with silent oper-
ation. Therefore, their natural location is in urban centres, where environmental
requirements are strictly related to noise.
Furthermore, versions A-E-U-N can produce water cooled to -10°C.
CONTROL
The controller with liquid crystal display is supplied as per standard with all the
units. It has a multilingual user interface, which is available also in remote version
(accessory) to be connected to the unit with serial connection.
The presence of an internal clock allows you to program the operation in time pe-
riods in order to improve the system efficiency and reduce consumption during
periods of non-use.
This option (Night Mode) is perfect for night operation, since it guarantees greater
acoustic comfort in the evenings, and a high efficiency in the time of greater load.
Night Mode for standard versions is mandatory DCPX accessory (stand-
ard on all low noise versions) or "J" inverter fan.
Systems consisting of two chillers allow the unit to be adjusted via (Master/Slave),
supplied as per standard. In case of several chillers through the Multichiller_EVO.
The supervision is possible thanks to different options, with proprietary devices or
by integrating other systems via ModBus, Bacnet, LonWorks etc. protocols.
VERSION WITH DESUPERHEATER OR TOTAL RECOVERY
Cooler complete with a desuperheater / total recovery section.
In this configuration a coolant/water heat exchanger is added on the gas flow line.
The exchanger is set i series before the condenser and is appropriately sized to
guarantee the recovery of all or part of the heat produced, for the free production
of hot water at a medium-high temperature for domestic or other uses.
Each exchanger is protected by an anti-freeze resistance.
DUAL-CIRCUIT UNIT
Unit with 2 refrigerant circuits designed to provide maximum efficiency at full load,
ensuring high efficiency at partial loads also and ensuring continuity in case one of
the circuits stops.
ALUMINIUM MICROCHANNEL COILS
The microchannel condensing aluminum coils ensure high levels of efficiency, re-
duced quantities of refrigerant and lower unit weight. The treatment "O" available
as configurator it ensures high resistance to corrosion even in the most aggressive
environments.
ELECTRONIC EXPANSION VALVE
The possibility to use electronic expansion valve, offers significant benefits, espe-
cially when the chiller is working with partial loads, increasing the energy efficiency
of the unit.
It is standard in all sizes from 1805 to 3600.
