CRA/Y 221÷802
Aircooled liquid chillers and heat pumps with
radial fans, semi-hermetic compressors and
shell and tube exchangers.
FROM 49 kW TO 165 kW.
UNIT DESCRIPTION
The indoor water coolers and heat pumps of the CRA/Y 221÷802 series
use the refrigerant HFC R134a, with minimum O.D.P. value, which allows
for significant energy savings in respect of the environment. These units
are particularly intended to satisfy the needs of medium/large-sized service sector or industrial rooms with particular difficulty in positioning units
outside the building.
They are used, combined with terminal units, for the air conditioning of
the rooms or to remove the heat developed during industrial processes;
they can be supplied with RS 485 ModBus connection to integrate, if
necessary, the innovative monitoring and control system CLIMAFRIEND
that allows to program up to 30 different environments in order to obtain
an optimal level of comfort intuitively and efficiently.
Equipped with centrifugal fans, semihermetic compressors and tubebundle exchangers, even in the version with high head fans, these units
can be completed by a hydraulic circuit with tank, with pump, or with tank
and pump. A wide range of accessories, factory-assembled or supplied
separately, complete the outstanding versatility and functionality of the
series.
