N/A Not available
The 30HXC 080-375 units for high condensing temperatures
are directly derived from the standard models. Their applicat-
ion 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 modifications are:
- Use of 30GX compressors
- Modification of electrical components to operate with
compressors for high condensing temperatures.
- Modification 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 45°C.
Like the standard units they are equipped with condenser
entering and leaving water sensors, installed on the piping.
It is possible to control the machine at the condenser water
outlet, requiring a factory configuration 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 configured 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 field wiring
connection, described in the chapter “Recommended selection”.
Refer to the dimensional drawings for these units, before
proceeding with the wiring.
Compressor
See 30GX compressor table.
Options and accessories
All options available for the standard 30HXC units are compa-
tible, except:
Option 5, brine unit Special unit
Option 25, soft start, 30HXC 200-375 units Not available
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 3 K
per minute. In cases where this is not possible, it is recom-
mended to go through a unit start/stop switch (remote start/
stop available for standard units).
