General
SYSCROLL AIR EVO has R410A refrigerant. As near azeo-
tropic mixture it behaves like a homogeneous substance
(reduced service problems in case of leakage or re-charge)
with negligible temperature glide.
Units with EER/COP values higher than 3.1/3.2 (energy
efciency class A).
With except for the fans, all the versions keep the same
conguration of the base units (same structure, electri-
cal board, compressors and coils).
Easy upgrade of the units in stock or on the eld.
Electronic expansion devices on all units: superheating
value controlled by microprocessor, simple and acces-
sible refrigeration system especially for heat pump ver-
sions with reduction of brazing points and than possible
leakage.
New Microchannel coils for Cooling only version.
Compressors box (less sound proong) always installed
- additional compressors jackets only for S version (easy
upgrade of the units in stock).
Inverter Fans Version (EC) developed for high seasonal
efciency (SEER higher than AC version) and wide op-
eration limits with large diameter electronic brushless
type fans motor. EC fans are standard for sizes 140-170.
Special version (HPF) for high external static pressure
(max. 120 Pa) with inverter fans (electronic brushless
type motor). Axial fan of large diameter. These fans are
the same as those used on EC units.
New microprocessor: 4 times greater RAM memory
compared with previous version, ash memory card and
compressors envelope curves put inside, 3 times faster
than previous control.
Hydro kits with or without buffer tank 350 liters 140-
170 and 500 liters 230-360 tted on board.
One or two water pumps are available: standard pres-
sure (100 kPa) or high pressure (200 kPa). The water
pump has a sound proof box for S version.
For service operation, special valves dedicated to R410A
are supplied on the refrigerant system. These valves, of
5/16” are SAE type, are mounted on the liquid line, dis-
charge, suction line and on the gauges manifold of the
unit.
