The 20 to 120 ton air-cooled chiller model CGAM is factory assembled, charged and designed for outdoor use in ambient temperatures of 0 to 125 F. Chillers are equipped with compressors, condenser, fans, evaporator and controls.
The industrial-grade design is ideal for large office buildings and commercial/industrial facilities. They install easily and quickly on the roof or ground for comfort or process cooling applications.
Trane AquaStream Liquid Chiller Features:
- Integrated solutions ranging from 20-120 tons capacity
- Energy efficiencies that exceed ASHRAE 90.1 standards and the Advanced Energy Design Guide for K-12 schools
- Reduced HFC-410A refrigerant charge earns LEED EA credit 4
- 5-8 dBA reduction in acoustic levels compared with current designs
- Ability to generate up to 140F leaving temperatures for heat recovery applications
- Increased reliability via rigorous accelerated life cycle testing and production process capability improvements that eliminate up to 60 braze joints per unit
- Improved serviceability - most major components within 18" of edge
Controls for reliability, efficiency, and system monitoring
Trane unit controls and building automation solutions leverage our applications expertise to meet your critical requirements. Adaptive Control algorithms embedded in the factory-mounted CH530 controller on the AquaStream chiller use Trane proprietary strategies to respond to normal, extreme or adverse conditions. The sophisticated algorithms intelligently maximize uptime while protecting equipment from damage.
Energy efficiency is more important than ever. CH 530 controller optimizes the AquaStream chiller's energy consumption. New sensing technology improves control of the electronic expansion valve, further raising efficiency. Tracer Summit building automation provides system and building wide energy optimization.
