This document is a detailed Model Number Description guide for Trane Air-Cooled Scroll Chillers and Heat Pump Chillers. The guide provides a comprehensive breakdown of a 45-digit model number, with each digit representing specific unit characteristics such as unit type (Air-Cooled Scroll Chiller or Heat Pump Chiller), nominal tonnage (ranging from 80 to 230 tons), compressor type, voltage, manufacturing location, sound package, agency listing, refrigerant charge, communication options, and wireless connectivity. The specification allows for extensive customization across multiple technical parameters including electrical accessories, flow control, fan types, condenser fin options, heat recovery, and shipping configurations. Specifically relevant to the associated federal contract opportunity, this document provides technical specifications for a 230-ton, 460-volt chiller to be installed at the AFGSC Annex building 4565 at Barksdale Air Force Base.
