Hermetic scroll compressors, low vibration and low sound
level
High efficiency plug fan for indoor installation with
ducted air intake and discharge. Optional EC plug fan for increased
external static pressure up to 400 Pa for improved capacity
modulation and energy savings.

heater
Electronic expansion valve
Microprocessor-based controller to manage unit on/off mode,
operating mode setting and parameters setting
Casing and
panels in galvanized and painted steel
Full compliance with
EU Regulation 2016/2281 for comfort chillers
Customer benefits
Compact dimensions allow for flexible installations in both
new and existing buildings
Maintenance operations are easy
thanks to the location of the components
Excellent acoustic
comfort levels
Digital Defrost is a self-adaptive
defrosting system able to intervene only in case of a consistent
thickness formation of ice on the coils’ fins
Dynamic Logic
Control manages the differential of the inlet water temperature on
the basis of the speed of its variation. Thanks to the DLC the
number of the compressor starts decreases ensuring economic and
energy savings
Dynamic Set Point function allows changing
the setpoint simultaneously to always achieve the conditions of best
comfort and maximum energy savings.
Perfect for large variety of buildings and applications
Building roof curved or not large enough
Floor-by-floor AC system with individual metering /
billing
Easy installation
of customized duct silencers satisfying
Specific noise
requirements
Allows isolating the machine
room from low outdoor air temperature
Examples:
Theaters/Hotels/Office buildings in (old) city centers
Areas with heavy air pollution. Indoor
installation protects unit against corrosion. Apply good
quality coating on condenser coil

Setpoint
arbitration is the strategy used to select final, authoritative
values from multiple input sources:
External inputs are
“hard wired“ directly to the local chiller controller with low
voltage binary (On/Off or Cool/Heat Mode)
External
setpoint with 4-20mA analog signals or double setpoint with
digital input. In this case it is necessary to order the iPRO
unit controller
BMS Inputs (Optional) are Building
Automation Systems which can talk to the chiller controls over
network serial links including Modbus, Lon Talk and BACNet. The
last two are available only with I-Pro.
