Accessories & Options
SYSCROLL AIR EVO Delivery Abbreviation Description & Benet
Set point timer/Clock card Std CLK
To schedule 4 different interval time with different active water T
setpoint.
Back light display Std User Display panel mounted. Suggested for outdoor installation.
Digital pressures and temperatures reading Kit Std
Pressure Transducers & Sensors to show the Discharge and
Suction pressure and temperature during running condition.
High pressure control on capacity Std
Functions able to protect multistage circuit from High discharge
pressure values. Circuit is partloaded whenever the Discharge pres-
sure is too high to prevent HP tripping.
Sequence phases control Std PHC
It allows to check the correct sense R-S-T of electric supply phases
for 400/3/50 units.
Electronic expansion valves Std EEV
It is the device able to control the refrigerant ow on suction line
trough a stepper motor in order to keep the superheat as constant
as possible.
Control circuit transformer 400V/230V Std TRF
Voltage transformer to provide correctly the separated voltage to
the auxiliary line.
Data logger Std DL
Record continuously the essential thermodynamic operating
parameters, during the last hours. This facilitates debug and service
activity on eld.
Power supply without neutral
Std
3PH
Unit to be supplied with 400/3/50. No need of Neutral cable.
Hour meter Std
Total running hours recorded for each compressors and for total
unit. Also record of total scroll compressors starts.
Main switch Std
Front operated switch-disconnector with direct mounted handle to
cut the power Supply Line according CE standards.
Differential pressure switch Std
Prevents the operation of the unit if the circulating chilled uid is
insufcient. Checking water differential pressure.
Antifreeze electric heater kit
Std
EEH
Electrical Heater protects the plate exchanger.
Compressor Jacket Std SLN CJ Jacket for each compressors in order to reduce the sound of its.
Remote On/Off control Accessory
It enables the operator to power on the unit when it is in standby
mode, to display alarms and switch over cooling–heat pump. Maxi-
mum length: 50mt.
