30RA010-055
Air-Cooled Chillers
10 to 55 Nominal Tons
(25 to 200 kW)
The AquaSnap chiller is an effective all-
in-one package that is easy to install
and easy to own. AquaSnap chillers
cost less to purchase and install, and
operate quietly and efficiently. Value-
added features include:
• Scroll compression
• Low profile construction
• Quiet AeroAcoustic™ fan system
• Easy to use ComfortLink™ controls
• Integrated hydronic pump package
• Accessory fluid storage tank

Features/Benefits

Carrier's superior chiller
design provides savings at
initial purchase, at installa-
tion, and for years afterward.
Costs less right from the start
Only Carrier's AquaSnap chillers fea-
ture a compact, all-in-one package de-
sign that installs quickly and easily on
the ground or the rooftop. The option-
al pump and hydronic components are
already built in; this costs less than buy-
ing and installing the components indi-
vidually. The chiller's fully integrated
and pre-assembled hydronic system in-
stalls in minutes. No other chiller in
this class installs so easily and inexpen-
sively. The preassembled and integrat-
ed hydronic module utilizes top-quality
components and pumps to ensure
years of reliable operation. Use of the
optional fluid storage tank reduces in-
stallation costs and ensures sufficient
fluid volume is available for close-cou-
pled and process cooling applications.
The AquaSnap unit's high efficiency
keeps costs down.
