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
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 install-
ing the components individually. The
chiller's fully integrated and pre-assem-
bled hydronic system installs in minutes.
No other chiller in this class installs so
easily and inexpensively. The preassem-
bled and integrated hydronic module uti-
lizes top-quality components and pumps
to ensure years of reliable operation.
Use of the optional fluid storage tank,
available on size 010-060 models, re-
duces installation costs and ensures suffi-
cient fluid volume is available for close-
coupled and process cooling applica-
tions. The AquaSnap unit's high effi-
ciency keeps costs down.
