The redefined Pathfinder is the first air-cooled chiller with variable-volume-ratio technology, which enables greater customization. It also is equipped with new variable-speed technology, offering easier maintenance and improved part-load performance. The new compressor automatically adjusts to job conditions, further optimizing performance. The configurability and wide array of options allow Pathfinder to achieve high part-load efficiencies and lower sound levels. Pathfinder is ideal for schools and office buildings. Mission-critical facilities such as hospitals and data centers benefit from Pathfinder’s RapidRestore feature, which has industry-leading compressor start times and fast load speeds. Additionally, the chiller’s R-134A refrigerant has no phaseout schedule and zero ozone-depletion potential, contributing to LEED certification. Initially offered in sizes ranging from 165 to 350 tons, Pathfinder will be offered in sizes over 350 tons starting in 2016.
