Features and Benefits |
Made in the USA
The new line of Trane Horizon™ two- stage
steam fired absorption water chillers is the only line
of two-stage absorption products designed and built
in the USA. Trane designs, tests and manufactures in an ISO9001 environment in
La Crosse, Wisconsin.
Leadership and Quality
Trane has been the market leader in absorption water chillers for over 35 years. The company has supported absorption
technology through the continuous application, design
and manufacture of absorption water chillers since 1959, with over 10,000 units built. Trane’s commitment extends
to the application of new product technology
development through extensive laboratory testing.
Factory-trained technicians provide start-up, maintenance and emergency service
support.
Efficiency
The Trane Reverse Series Cycle can be as much as 5-15 percent more efficient at full load than other cycles. But full load
is not the whole story. The Trane microprocessor based
control (UCP2) along with variable speed pumps optimizes the machines performance at partload conditions to provide significant
operating cost savings. IPLV values up to 1.35 at ARI
conditions.
Chilled water temperatures as low as 40 F (+4.4 C) can take advantage of lower HVAC equipment costs and reduced
operating costs. Low temperature chilled water systems
can improve IAQ by reducing the humidity in the occupied spaces. It also allows the designer to reduce distribution expenses
such as pumps, fans and ductwork.
Fully Automatic Purge System
Trane’s new purge system removes non-condensables from the machine continuously
and automatically while logging purge information
through the UCP2. This prevents damage to the machine while maintaining the machine’s
peak performance.
Automatic Crystallization Protection
When/Why it Occurs
Crystallization results from operating conditions that cause the solution to solidify forming salt crystals which precipitate
out and eventually restrict flow. This may result in a
chiller failure that is difficult to correct.
Concentration control maintains solution concentrations to avoid crystallization. And, in the event of crystallization, SDR is
an automatic corrective action process.
Concentration Control
The UCP2 concentration control adjusts the energy input for optimum solution efficiency. The strong solution concentration
is typically maintained 15 degrees F (-9.4 C) from
theoretical crystallization point. This is called the
low temperature heat exchanger (LTHX) margin. As strong solution concentration
is varied by the leaving water temperature solution
flow control, the theoretical crystallization temperature is changed. The control system adjusts the energy input to maintain
the LTHX temperature margin throughout the load range. |
