Pathfinder Chiller - 175 to 530 tons,

Model AWS, R-134a

Pathfinder™ Air-Cooled Chillers—175 to 530 Tons

• Three levels of efficiency

- Standard: meets ASHRAE Standard 90.1 for efficiency

- High: enhanced efficiency, up to 10.8 EER at full load

- Premium: highest full load efficiency in its class with part load efficiency
that rivals competitive chillers with VFDs

• Integrated VFD further optimizes part load efficiency to redefine world class
performance

• Quietest air cooled screw chiller available, with sound pressure levels as low
as 65 dBA with no attenuation

- Patented condenser fan moves maximum amounts of air with minimal

sound

- Unique screw compressor with single main rotor and dual gaterotors

operates more quietly than dual rotor screw compressors

• Contributes to Leadership in Energy and Environmental Design (LEED
Green Building Rating System™ points for enhanced refrigerant
management and optimized energy efficiency

• Small unit footprint makes it ideal for retrofit and replacement projects

• All Pathfinder Chillers shipped in North America are D-Net™ remote service
capable, providing a direct electronic connection to a Pathfinder Chiller and
the ability for enhanced level of support to keep the chiller running efficiently
and reliably

• Application flexibility with remote evaporator option available on standard
efficiency units
