Carrier 30HXC - Compressor Electrical Data 30 HXC + Option 150;150 A

16
The 30HXC 080-375 units for high condensing temperatures are
directly derived from the standard models. Their application
range is the same as that of the standard units, but permits
operation at condenser leaving water temperatures up to 63°C.
The PRO-DIALOG control offers all the advantages of the
standard units, plus control of the condenser leaving water
temperature.
The main modications are:
• Use of high lift compressors (example: 06NA2300S5N
instead of 06NW 2300S5N).
• Modication of electrical components to operate with
compressors for high condensing temperatures.
• Modication of heat exchangers to meet pressure code
requirements (if necessary).
Option 150
These units are designed for traditional applications for water-
cooled units, but for higher condender leaving water temperatures
than 50°C.
Like the standard units they are equipped with condenser entering
and leaving water sensors.
It is possible to control the machine at the condenser water outlet,
requiring a factory conguration change and the use of a heating/
cooling inlet reversing device.
Option 150A
These units are designed for water-to-water heat pumps.
They are factory congured as heat pumps (heating/cooling control
as a function of the remote reversing device). The condenser
incorporates thermal insulation that is identical to that of the
evaporator.
Technical information
All information is identical to that of the standard 30HXC units,
except for the following paragraphs.
Selection
There are no nominal conditions for this unit type. The selection
is made using the current electronic catalogue.
Dimensions
These are identical to those of the standard 30HXC units. The
only difference is in the diameter of the incoming eld wiring
connection, described in the chapter “Recommended selection”.
Refer to the dimensional drawings for these units, before
proceeding with the wiring.
Compressor
See table in chapter 4.5.
Options and accessories
All options available for the standard 30HXC units are compatible,
except low-temperature option 5 for the evaporator available in
the special unit.
ATTENTION: If units have two different operating modes - one
with high condensing temperature and the other with low
condensing temperature - and the transition is made with the
unit in operation, the temperature must not vary by more than
3K per minute. In cases where this is not possible, it is
recommended to go through a unit start/stop switch (remote
start/stop available for standard units).
