Features and Benefits
Reliability
• Years of laboratory testing, including running the chiller at extreme operating conditions, have
resulted in optimized compressor and chiller systems reliability by confirming a robust design
and verifying quality each step of the way.
• Direct-drive, low-speed scroll compressors with fewer moving parts provide maximum
efficiency, high reliability, and low maintenance requirements. Suction gas-cooled motor stays
at a uniformly low temperature for long motor life.
• The third generation microprocessor control system provides improved control capabilities
with Adaptive Control™ to keep the unit operating even in adverse conditions. Advanced
microelectronics protect both the compressor and the motor from typical electrical fault
conditions like thermal overload and phase rotation.
• Standard factory-installed water strainer helps prevent system debris from affecting unit flow
or heat transfer.
• Flow switch is factory-installed at the optimum location in the piping for reduced chiller
installation cost and superior flow sensing, reducing the potential for nuisance trips.
• Exceptionally rigid condenser coil structure is manufactured with hairpin tubes which halves
the number of braze joints significantly reducing the potential for leaks.
• Innovative condenser pressure integrated fan control algorithms and variable frequency drive
on circuits’ lead fans provides more reliable operation at extreme temperature conditions.
Life Cycle Cost-Effectiveness
• Industry leading full- and part-load efficiency
• Electronic expansion valve and high speed suction temperature sensor enables tight chilled
water temperature control and low superheat, resulting in more efficient full-load and part-load
operation than previously available.
• Partial heat recovery available to save energy on pre-heat or reheat applications.
• Pump package features standard variable speed drive on the pump motors eliminating the
need for energy sapping chilled water system triple duty or balancing valves. Additionally,
system commissioning and flexibility is greatly enhanced. Chilled water supply reliability is
increased with the dual pump design, due to standard failure/recovery functionality.
Application Versatility
• Industrial/low temperature process cooling - Excellent operating temperature range and
precise control capabilities enable tight control.
• Ice/thermal storage - Utilities and owners benefit from reduced cooling energy cost.The
chiller’s dual setpoint control and industry leading ice energy storage efficiency assures reliable
operation and superior system efficiencyTrane’s partnership with CALMAC, brings a proven
track record of successful installations across many markets; from churches and schools to sky
scrapers and office buildings.
• Partial heat recovery -An optional factory-installed heat exchanger provides hot water for many
needs; water preheat and reheat for enhanced system humidity control are just two.This option
reduces operating costs associated with boilers/domestic hot water.
