Identifying prefix of the Mercury family
Air discharge
U = Upflow (upwards discharge)
D = Downflow (downwards discharge)
Operating typology
C = Chilled water units
A = Air cooled direct expansion units
W = Water cooled direct expansion units
Fan typology
V = Radial Electronically Commutated fans
B = Radial fans
MODELS
The code which distinguishes the models is composed of 9 characters:
IDENTIFICATON PLATE
The units can be identified by the identification plate which is placed in the electrical panel of the machine. The model and
any eventual accessories which are installed are indicated by an "X" in the corresponding box
The plate carries the following data:
Model and series number of the machine.
Type of power supply.
Power absorbed by the unit and the single components.
Current absorbed by the unit and the single components.
The set points of the cooling circuit pressostatic valve and safety valve.
Type of refrigerant.
Loading or pre-loading of each cooling circuit.
Indicative cooling capacity
Number of compressors installed
Number of cooling circuits
Power supply voltage
A = 400 V / 3Ph (+N) / 50 Hz

AIR COOLED DIRECT EXPANSION UNITS (DXA)
The air cooled DX units extract heat from the room and transfer it to
the outside using air cooled refrigerant heat exchangers (condensers).
The room unit and external condenser form an autonomous sealed circuit
once installed. The TRANE remote condensers used with MERCURY
units include a precise electronic system to regulate the fan speed to
ensure trouble-free operation throughout the year under a wide range of
external air temperatures. Special attention has been paid to the acoustic
design of the condensers to minimise noise levels. A wide range of
combinations is available to meet different site requirements.
WATER COOLED DIRECT EXPANSION UNITS (DXW)
In the DX water cooled units, the heat extracted from the room is
transferred to water via a stainless steel brazed plate exchanger within
the unit.
The cooling water may be fed from the mains supply, a cooling tower or
a well (open circuit), or recycled in a closed loop cooled by external
coolers.
In the latter case, an anti-freeze mixture of water and ethylene glycol is
normally used.
The water cooled units have the advantage that the refrigerant circuits
are charged and sealed in the factory. This makes installation extremely
simple, eliminating the need for any site-installed refrigerant pipework.
