Features/Benefits

The externally geared 17EX
open drive centrifugal liq-
uid chiller features:

Single-piece factory package —

The 17EX chiller is completely
assembled in the factory and shipped
in one piece to the jobsite. This allows
each unit to be tested before delivery
to the customer. It also ensures that
every aspect of the unit meets stringent
quality standards specified by Carrier.
One piece shipment eliminates costly
and time consuming field assembly.

Modular construction —

The

cooler, compressor, condenser, and
economizer/storage vessel assemblies
are completely bolted together,
making the 17EX chiller ideally suited
for replacement projects where ease
of disassembly and re-assembly at the
jobsite are essential.
