Accessories & Options
SyScroll Air Delivery Abbreviation Description & Befenit
Sequence phases control Std PHC
It allows to check the correct sense R-S-T of electric supply phases
for 400/3/50 units.
Control circuit transformer 230V/12V Std TRF
Voltage transformer to provide correctly the separated voltage to
the auxiliary line.
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.
Low ambient kit
(pressostatic stepless fan speed control)
Std FSC
Electronic speed controllers are designed to control the speed
of fan motors in Air Cooled Chiller and Heatpump. Fan Speed
controlled by Condensing Pressure in cool mode or by Air Temp in
heat mode. Using variable fan speed controllers offers following
benets in commercial refrigeration or air-conditioning applications
High Efciency, Low Noise level, Low air temperature in cool mode
and High air temperature in heat mode.
Double set point Std DSP
Can manage two different applications (set point) selected by
remote dry contact.
Automatic circuit breaker Std ACB
ACB is an automatically operated electrical switch designed to
protect an electrical circuit from damage caused by overload
or short circuit. Providing Magnetic and Thermal protection to
Compressor motors.
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.
Compressor Jacket Option CJ Jacket for each compressors in order to reduce the sound of its.
Modbus protocol kit for BMS Option MBS
It permits the integration of the unit with BMS with Modbus
protocol trough RS485 port.
Softstarter for compressor Option SS
An electronic device that automatically starts up the compressors
gradually. The starting current can be reduced by up to 40% of the
direct on line value.
Power factor corrector capacitors Option PFC
The purpose of the power factor corrector capacitor is to minimize
the input current distortion and make the current in phase with the
voltage. Target is to keep Power Factor about 0.90 in any running
condition.
Mechanical gauges kit (HP and LP manometers) Option KM
Pressure gauges that display the operating pressure in the high and
low pressure sections of the refrigerant circuit.
e-coating AL/CU Option
It is a treatment fo AL/CU coil for medium level of pollution and for
marine atmosphere.
Coil Guards Option CG Grilles to protect the coils.
Desuperheater Option D
Additional exchanger in order to recover 20% of capacity for
Domestic Hot Water application.
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.
Maximum lenght: 50mt.
Remote keyboard panel Accessory
Makes it possible to control the unit through the remote terminal,
up to a maximum distance of 100mt of telephone cable.
Sequencer for up to 4 chillers installation Accessory SEQ
It can easily pilot up to 4 units, chiller or heat pumps, belonging to
the same family, tted in parallel, 50 metres apart maximum.
Flow switch Accessory FS
Prevents the operation of the unit if the circulating chilled uid is
insufcient. It is recommended to install a ow switch to ensure the
correct operation of the unit.
Water pressure switch Accessory
Mechanical water pressure switch to be mounted on the eld
installation on installation water piping to prevent very low Water
Pressure.
Water lter Accessory Filter to remove impurities from the water supply.
Valve in out Accessory
Ball valves makes it possible to insulate unit hydraulic circuit from
the rest of the installation.
Accessories are loosed and to install in the eld. Options are mounted in factory.
