3 - Receiver Height Above Ground = 0.0 ft
Estimated Sound Power levels - dB re: 1 picowatt
Estimated Sound Pressure levels - dB re: 20 micropascal
Estimated sound levels given above are assumed to originate at the acoustic center of the chiller.
Sound pressure level data used to develop this program was determined in accordance with AHRI Standard 575 for water chillers in a
free field and ANSI/AHRI Standard 370 for air cooled chillers.
Calculation methods used in this program are patterned after the ASHRAE Guide; other ASHRAE Publications and the AHRI Acoustical
Standards. While a very significant effort has been made to insure the technical accuracy of this program, it is assumed that the user
is knowledgeable in the art of system sound estimation and is aware of the tolerances involved in real world acoustical estimation.
This program makes certain assumptions as to the dominant sound sources and sound paths which may not always be appropriate to
the real system being estimated. Because of this, no assurances can be offered that this software will always generate an accurate
sound prediction from user supplied input data. If in doubt about the estimation of expected sound levels in a space, an Acoustical
Engineer or a person with sound prediction expertise should be consulted.

a30-5347
Copyright 2012 Carrier Corporation
Carrier’s AquaSnap chillers feature a
compact, all-in-one package design that
installs quickly and easily on the ground
or the rooftop. The optional pump and
hydronic components are already built
in; this costs less than buying and installing the components individually. The
chiller’s fully integrated and pre-assembled hydronic system installs in minutes.
No other chiller in this class installs so
easily and inexpensively. The preassembled and integrated hydronic module utilizes top-quality components and pumps
to ensure years of reliable operation.
Use of the optional fluid storage tank,
available on size 010-060 models, reduces installation costs and ensures sufficient fluid volume is available for closecoupled and process cooling applications. The AquaSnap unit’s high efficiency keeps costs down.

Features/Benefits (cont)
AquaSnap® chillers make
noise in the marketplace, not
the workplace.
The AquaSnap chiller’s low-sound
AeroAcoustic™ fan produces up to half
the sound level of propeller fans. Much
of the noise reduction is in frequencies
where noise is most annoying, which
makes AquaSnap chillers ideal for
sound-sensitive environments. When
lower ambient temperatures allow part
load operation or during scheduled
nighttime operation, the units operate
with fewer fans and become even quieter. AquaSnap chillers are quiet during the day and even quieter at night.
The savings will continue to
mount
Besides costing less to buy and install,
AquaSnap chillers are also more affordable to operate. Carrier’s Aqua
Series chillers are our most efficient
air-cooled models. The AquaSnap
chiller provides full load EER (Energy
Efficiency Ratio) up to 10.5 and IPLV
(integrated part load value) up to 15.9.
AquaSnap chillers use ultra-quiet, highefficiency rotary scroll compressors,
operated in single (sizes 010 and 015)
tandem (sizes 018 to 060), and tandem or trio (sizes 070 to 090) per independent circuit for greater efficiency
at partial loads.
Electronic expansion valve (EXV)
allows for precise control through all
operating ranges, resulting in higher
efficiency and improved reliability.
Proven reliability that’s built in
Thousands of AquaSnap chillers are
already in service around the world.
Table of contents
This field-proven design is backed by a
12-month warranty that includes the
hydronic system. The compressors are
maintenance-free and protected by an
auto-adaptive control that minimizes
compressor wear. Unit sizes 035 and
up have two independent refrigerant
circuits. Year-round operation is
standard, from –20 F (–29 C) (with
optional cooler heater, low ambient
control, and wind baffles) to 120 F
(50 C).
Rotary scroll compressors provide
smooth, quiet and reliable operation.
• Pressure/temperature taps
• Isolation valves for dual pump
systems
• VFD available on sizes 070 to 090,
and VFD compatibility on all models
The factory-installed and tested hydronics package provides faster, simpler and less expensive installation.
Digital scroll compressors are
available as a factory-installed option.
These allow for incremental unloading
with capacity modulation to better
match building load when compared to
standard scroll compressors.
All-in-one package
Environmentally sound
AquaSnap chillers provide the most
comprehensive chilled water circuit
available for any air-cooled chiller.
Included is a brazed plate direct
expansion cooler that may be remotemounted. The cooler is also completely
drainable with factory-installed vents
and drains.
Electronic thermal-dispersion
flow switch is included with the cooler. The switch is factory installed and
tested and contains no moving parts
for high reliability.
Optional integrated hydronics
package is more than just a pump, it
is an entire chilled water system,
including:
• Single/dual pumps up to 15 hp
and 160 ft head
• Regular strainer
• Cleanout strainer
• Flow regulator
• Freeze protection to –20 F (–29 C)

Carrier’s Puron® refrigerant (R-410A)
enables you to make a responsible decision in the protection of the earth’s
ozone layer. Puron refrigerant is an
HFC refrigerant that does not contain
chlorine that is damaging to the ozone
layer. Puron refrigerant is unaffected
by the Montreal Protocol. Puron refrigerant is a safe, non-toxic*, efficient and
environmentally sound refrigerant for
the future.
Durable construction
The 30RAP chillers have a structurally
sound base that can be point-loaded,
therefore, no perimeter base rail is required. All 30RAP units have weatherized cabinets constructed of heavy-duty
galvanized steel with exterior panels
painted with corrosion-resistant baked
enamel. Inside and outside surfaces are
protected to ensure long life and good
appearance. The durable, galvanized
steel, painted components exceed the
requirements of the 500-hour salt
spray test per ASTM (American Society for Testing and Materials) B117.
ComfortLink controls speak
your language
The ComfortLink controls communicate in plain English, making it as easy
as possible to monitor and control
each AquaSnap chiller while accurately
maintaining fluid temperatures. The
large scrolling marquee display acts as
a window into the unit’s operation,
providing easy-to-read information
about chiller performance and over
15 diagnostic functions. Carrier 30
Series chillers’ ComfortLink controls
provide features such as chilled water
temperature reset, demand limiting,
compressor wear minimization and
protection, temperature and pressure
displays and diagnostic functions.
CH-1
These controls result in higher chiller
reliability, simplified training and more
productive service calls with correspondingly lower operational and
maintenance costs.
Carrier’s exclusive accessory handheld Navigator™ display provides convenience and powerful information in
the palm of your hand. The Navigator
display helps technicians to quickly
diagnose problems and even prevent
them from occurring.
All AquaSnap units are ready to
be used with the Carrier Comfort
Network® (CCN) system.
A BACnet† communication option
is also available for the i-Vu® Open
control system or a BACnet building
automation system.
data, the E-Cat program output will advise the appropriate coil to be used.
Other factors described in "Selection
Guide: Environmental Corrosion Protection, Novation Heat Exchanger with
Microchannel Coil Technology" catalog
number 04-581042-01 must also be
considered to determine if corrosion
protection is required.
Microchannel coils are more robust
than other coil types, making them
easier to clean without causing damage
to the coil.
Due to the compact all aluminum
design, microchannel coils will reduce
average unit operating weight by 25%
compared to the previous 30RA units.
The streamlined MCHX coil design
also reduces refrigerant charge by an
average of 60% compared to previous
30RA units.
AquaSnap units minimize the
impact on your footprint, as
well as your bottom line
The integrated hydronics and the
chilled fluid storage tank’s placement
under the chiller minimize the footprint, allowing easy installation almost
anywhere.
Novation® heat exchanger
technology
The Novation heat exchanger design
with microchannel (MCHX) condenser
coil is a robust, cost effective alternative to traditional coil design. These
coils are offered coated or uncoated to
match coil protection to site conditions. The Carrier Electronic Catalog
(E-Cat) can be used to determine
whether or not corrosion protection is
recommended for particular applications in coastal/marine environments.

determine whether or not corrosion protection is recommended for particular applications in coastal/marine environments. Following the input of the requested data, the ECat program output will advise the appropriate coil to be
used. Other factors described in "Selection Guide: Environmental Corrosion Protection, Novation Heat Exchanger
with Microchannel Coil Technology" catalog number 04581042-01 must also be considered to determine if corrosion protection is required.

Selection procedure
Carrier’s electronic catalog chiller selection program provides quick, easy selection of Carrier chillers. The program
considers specific temperature, fluid, flow requirements,
system pressure drop (for proper pump selection, when
required), as well as other factors, such as fouling and
altitude correction.
To select a 30RAP chiller, including optional pump
package when required, use the NACO (North American
Commercial Operation) Packaged Chiller Builder Program.
