KEY FEATURES & BENEFITS

Trane Ascend™ Platform:

• Premium air-cooled screw chiller platform engineered for superior efficiency, reliability, and serviceability
• Designed for large commercial and industrial applications requiring dependable chilled water production without the complexity of a cooling tower
• Backed by Trane's global service network and parts availability
• Factory-new condition — no deferred maintenance, no unknown service history

Exceptional Part-Load Efficiency:

• IPLV of 18.92 EER (Btu/W-h) — industry-leading part-load efficiency
• 22 VFD-controlled condenser fan motors allow precise airflow modulation to match ambient and load conditions
• Dramatically reduced energy consumption during part-load operation vs. fixed-speed fan designs
• Significant operating cost savings over the life of the equipment

Dual Independent Refrigerant Circuits:

• Two fully independent refrigerant circuits with separate compressors
• If one circuit requires service, the second continues to operate — maintaining partial cooling capacity
• Increased redundancy and operational flexibility for mission-critical applications
• R-513A low-GWP refrigerant — non-flammable, environmentally compliant, aligned with current and future regulations

VFD Condenser Fan Technology:

• All 22 condenser fan motors are VFD-controlled
• Stepless speed modulation from minimum to maximum airflow
• Quieter operation and reduced mechanical wear vs. fixed-speed fans
• Significant energy savings at ambient temperatures below design day

New, Never Installed Condition:

• Unit is factory-new and has never been put into service
• Still loaded on flatbed trailer — ready for rigging and transport
• Significant opportunity to acquire a premium chiller at a fraction of new equipment lead times (12–24 months for this capacity class)
• All factory documentation and specifications intact

Natural Applications:

• Large commercial office buildings and campuses
• Industrial manufacturing facilities
• Data centers and critical facilities
• Hospitals and healthcare campuses
• Universities and institutional facilities
• Any application requiring high-capacity, reliable chilled water production
