Features/Benefits
ComfortLink control
Your link to a world of simple and easy to use
air-cooled chillers that offer outstanding
performance and value. The 30GTN,GTR,
GBN,GBR liquid chillers employ more than the
latest advanced microprocessor controls, they
utilize an expandable platform that grows as
your needs change. From stand-alone operation
to remotely monitored and operated multi-
chiller plants, ComfortLink controls can keep
you plugged in.
ComfortLink controls are fully
communicating, and are cable ready for
connection to a Carrier Comfort Network
(CCN). Occupancy scheduling, temperature
and pressure read-outs, and the ComfortLink
scrolling marquee clear language display
compliment the standard features, linking you
to a world of carefree comfort. The
30GTN,GTR,GBN,GBR chillers are built on
the legendary performance of the Carrier model
30G Flotronic™ chiller and share many of the
same time-proven features and technologies
providing easy operation, quick installation and
start-ups that save you money!
Superior temperature control equals
potential for greater productivity
Whether in the classroom, on the production
floor, or in the office, ComfortLink controls can
help you to adapt to changing weather and
business conditions. Accurate temperature
control provided by the Carrier ComfortLink
system helps to maintain higher levels of indoor
air quality, thermal comfort, and productivity
space.
While many air-cooled chillers use only
leaving fluid temperature control, the
30GTN,GTR,GBN,GBR chillers utilize leaving
fluid temperature control with a standard
entering fluid temperature compensation.
