General description
SYSCROLL AIR EVO CO / HP units have been designed and
optimized to operate with R410A refrigerant and Scroll
compressors.
Thanks to multi-scroll technology and asymmetric design
in refrigerant circuits, it is possible to reach very high level
of full load efciency (EER up to 3,2 and COP up to 3,3)
and seasonal efciency (SEER up to 4,5 and SCOP up to
3,9), in line with Ecodesign requirements.
SYSCROLL AIR EVO CO units are available in 10 sizes, with
a nominal capacity range from 399 to 897 kW.
SYSCROLL AIR EVO HP units are available in 11 sizes, with
a nominal capacity range from 374 to 839 kW in cooling
mode and from 404 to 902 kW in heating mode.
Units from size 400 to size 670 are equipped with two
separated refrigerant circuits, each one equipped with 2
or 3 compressors (tandem / trio installation)
Units from size 750 to size 900 are equipped with four
separated refrigerant circuits, each one equipped with 2
compressors (tandem installation)
SYSCROLL AIR EVO can be supplied with 2 acoustic op-
tions:
Basic Low Noise (-): units are equipped with delta con-
nected fans and compressors box to reduce the noise
emission
Super Low Noise (S): units are developed on a longer
chassis to keep same level of performances as the basic
unit, with lower sound emission. CO units are equipped
with star connected fans, while HP units are equipped
with delta connected fans; in both cases fans are man-
aged by a speed controller setting the rotation speed to a
lower level. Units are also supplied with compressors box
and soundproof jackets on compressors
To increase application eld, SYSCROLL AIR EVO range is
available in four additional versions:
High Temperature (HT): units (CO version only) are de-
veloped on a longer chassis and they are tted with
brushless EC fan motors to ensure low energy con-
sumption and to operate on a wider envelope
High Pressure Fans (HPF): same equipment as the basic
version, but also tted with brushless EC fan motors so
as to provide external static pressure up to 120 Pa
EC: same equipment as the basic or Super Low Noise
version, but also tted with brushless EC fan motors to
ensure low energy consumption and low sound emis-
sion
Brine Cooling (BC): same equipment as the basic CO
version, with brushless EC fan motors and customized
refrigerant circuit to extend operating envelope to neg-
ative water set-point
Polar Heating (PH): same equipment as the basic HP
version, with brushless EC fan motors and dedicated
electrical and mechanical options to extend operating
envelope to negative outdoor air temperatures and to
simplify maintenance operation
Two heat recovery options are available:
Desuperheater: plate type heat exchangers tted on the
compressor discharge line, to recover about 20 % of the
total heat rejected to the condensers
Total Heat Recovery (TR): double circuit plate type heat
exchanger to recover the total heat rejected to the con-
densers. 4-way valves and eld installed control sensor
are also provided to ensure the cooling/heat recovery
mode changeover
Several hydraulic options are available in order to cover
a wide range of requirements in terms of pump available
static pressure, redundancy and inertia water side
The general operation status of the unit is steadily man-
aged by a microprocessor implementing a dedicated de-
veloped software, ensuring a total protection of compres-
sor inside its operating envelope and including parameter
customization according application eld.
