(Brushless) for continuous operation as a chiller up to -15°C outdoor air
temperature
FIAP - Condensing control with over-pressured fans with EC motor
(Brushless) and available static head according to the following table:
Available static head
Single fan absorption
Average increase in noise of the unit
SFS – Soft Starter compressors.
CR - Power factor correction capacitors
IM - Unit with circuit breaker switches protecting compressors and fans
FDL - Forced Download Compressors Compressor status management
(forcing them to OFF or limiting them) to limit the power and absorbed
current

or time band management) - See specific section for more information
GM - Refrigerant circuit high and low pressure gauges.
RQE - Electrical panel resistance (recommended for low outdoor air
temperatures)
RA - Evaporator antifreeze resistor to prevent the risk of ice formation
inside the exchanger when the machine is switched off (as long as the
unit is not disconnected from the power supply).
RDR - Antifreeze electric heater for desuperheater / heat recovery (DS
or RC100), to prevent the risk of ice formation inside the recovery
exchanger when the machine is switched off (as long is the unit is not
disconnected from the power supply).
RAE1 - Electric pump antifreeze heater (available for P1-P2 set ups);
used to prevent the risk of the water inside the pump from freezing
when the machine is switched off (provided the unit is not disconnected
from the power supply)
RAE2 - Antifreeze heater for double electric pumps (available for DP1-
DP2 set ups); used to prevent the risk of the water inside the pump from
freezing when the machine is switched off (provided the unit is not
disconnected from the power supply)

the DSP accessory).
CMT - Control of minimum and maximum values of power voltage.
BT – Low temperature of water produced.
SS - RS485 interface for serial communication with other devices
(proprietary protocol; Modbus RTU protocol)
EEM – Energy Meter. Measure and display values of the electrical units
FTT10 - LON interface for serial communication with other devices
(LON protocol).
RPB - Coil protection networks with accident prevention function (to be
used as an alternative to the FMB accessory).

PTL - Side damping panels within an aesthetic, accident prevention and
anti-intrusion function (to use as an alternative to the RPB accessory
and only for chiller models).
DVS – High pressure double safety valve with exchanger tap (the valve
is only on the outlet branch. In the case of options, such as DS/RC100
recovery units or tube and shell heat exchangers, please contact the
Pre-Sales department for a quotation and feasibility of the additional
double valves).

Guide to choosing the MCXHE accessory

The aluminium alloys used in MCHX are the best available. However,
even the best aluminium alloy needs further protection against
corrosion in corrosive environment.
The purpose of this document is to guide our customers in choosing the
MXCHE accessory. To do this, attention is required to the classification
of different environments in relation to pollution and corrosion of the
metal.
