Features and
Benefits
General
Sophisticated Reliability
Horizon controls meet specifications for
stand alone or hybrid chiller control.
UCP2 adaptive controls are critical to
reliable operation. Trane controls are
compatible with Integrated Comfort
™
Systems (ICS), and are easily integrated
into the Tracer
®
family of flexible chiller-
plant system controllers with a single
twisted-pair communications cable.
Ideal for Process and Commercial
Applications
With Horizon chillers, the application
possibilities for the absorption machine
are expanded. Capabilities such as lower
tower flow, variable evaporator flow,
lower chilled-water temperatures and
advanced control capabilities make the
single-stage Horizon absorption chiller
ideal for both process and comfort
applications.
When Long-lived Reliability
Is Important
Trane has been a long-time proponent of
the use of high-quality materials in
absorption chiller designs. The lithium
bromide temperatures and water
refrigerant, typical of all absorbers, can
more quickly corrode lower-grade metals
in the presence of air. Trane recommends
and uses industrial-grade materials to
provide long-lived, reliable cooling.
A Global Network of
Absorption Expertise
When you specify a Trane Horizon
chiller, you’re getting the knowledge,
expertise and assistance of a pool of
experts that have decades of absorption
expertise. Making The Trane Company
part of your management team gives
you access to refrigeration, air
conditioning and facility control-system
applications specialists, and a unique
breadth of innovative solutions to satisfy
your facilities needs for today and
tomorrow.

Absorption Cooling —
A Sound Decision
Life-cycle costing has become a primary
concern for chiller buyers who have
long-term investment opportunity in
mind. Changes in the distribution and
pricing of electricity have made the
absorption water chiller a popular choice
when alternative energy use makes
sense. Ask your local Trane
representative for a comprehensive
analysis of your facility, and the energy-
saving opportunities Trane offers for the
design of Heating, Ventilating and Air
Conditioning systems and controls.
