Features and Benefits
Reliability
• The Trane helical rotary compressor is a proven design resulting from years of research and
thousands of test hours, including extensive testing under extraordinarily severe operating
conditions.
• Trane is the world’s largest manufacturer of large helical rotary compressors, with more than
240,000 compressors installed worldwide.
• Direct drive, low-speed compressors—a simple design with only four moving parts—provides
maximum efficiency, high reliability, and low maintenance requirements.
• Suction gas-cooled motor stays at a uniformly low temperature for long motor life.
• Electronic expansion valve, with fewer moving parts than alternative valve designs, provides
highly reliable operation.
High Performance
• Advanced design enables chilled water temperature control to ±0.5°F (0.28°C) for flow changes
up to 10 percent per minute, plus handling of flow changes up to 30 percent per minute for
variable flow applications.
• Two minute stop-to-start and five minute start-to-start anti-recycle timer allows tight chilled
water temperature control in constant or transient low-load applications.
• High compressor lift capabilities for use with heat recovery and waterside heat pump
applications allows highly efficient system design with minimal operational concerns.
• Tight water temperature control extends to operation of multiple chillers in parallel or series
configurations, offering further system design flexibility for maximum efficiency.
• Optional LonTalk/Tracer Summit communications interface provides excellent, trouble-free
inter operability.
Life Cycle Cost-Effectiveness
• Precise compressor rotor tip clearance ensures optimal efficiency.
• Condenser and evaporator tubes use the latest heat transfer technology for increased
efficiency.
• Electronic expansion valve enables exceptionally tight temperature control and extremely low
superheat, resulting in more efficient full-load and part-load operation than previously
available.
• Chilled water reset based on return water temperature is standard.
• Electrical current-limiting is available as an option.
