Applications Options
Ice Making
The ice making option provides special control logic to handle low temperature brine applications
(less than 40°F [4.4°C] leaving evaporator temperature) for thermal storage applications.
Low Temperature Brine
The low temperature option provides special control logic to handle low temperature brine
applications (less than 40°F [4.4°C] leaving evaporator temperature) including part load conditions.
Low Ambient Option
The low ambient options adds hardware and unit controls to allow start and operation down to
ambient temperatures of 0°F (-17.7°C).
Extreme Low Ambient Option
The low ambient options adds hardware and unit controls to allow operation down to ambient
temperatures of -20°F (-28.9°C).
High Ambient Option
High ambient option consists of special control logic, compressor motors, and variable speed
drives to permit high ambient (up to 125°F [51°C]) operation. Low side ambient remains 32°F (0°C).
Wide Ambient Option
The low and wide ambient option combines the features of low and high ambient options for an
ambient range of 0 to 125°F (-17.7 to 51°C).
Electrical Options
Circuit Breaker
A HACR rated molded case capacity circuit breaker (UL approved) is available. Circuit breaker can
also be used to disconnect chiller from main power with a through-the-door handle. It comes pre-
wired from factory with terminal block power connections. External operator handle is lockable.
Harmonic Attenuation
Harmonic attenuation to comply with IEEE 519 is available. It is important to recognize that IEEE
519 as a guideline relates to the entire system, not specifically to any one load or product. IEEE 519
establishes requirements at the point of common coupling (PCC) where the building connects to
the utility system. The standard contains no specific requirements for the internal electrical loads.
Even though Trane AFD-equipped chillers will attenuate their own harmonics, other nonlinear
loads on the same system could still create harmonic problems. In buildings where harmonics
might be a concern, Trane recommends conducting a power-distribution system analysis to
determine if there is a need to further attenuate harmonics at the system level.
