Trane CGAF-C20 20-Ton Air Cooled Chiller 460V 3-Phase Intellipak R-22 CGAFC204AE

Trane CGAF-C20 20-Ton Air Cooled Chiller 460V 3-Phase Intellipak R-22 CGAFC204AE

The Trane CGAF-C20 is a 20-ton air-cooled process water chiller built on Trane's CGAF platform, equipped with the Intellipak microprocessor control system. It uses two Trane 3-D Scroll compressors across two independent refrigerant circuits, rejects heat through air-cooled condenser coils, and is designed for outdoor non-residential installation. This unit runs on 460V/3-phase/60Hz power and uses R-22 refrigerant.

Applications

Air-cooled process water chillers like the Trane CGAF series are used to remove heat from industrial processes, manufacturing equipment, and commercial HVAC systems by circulating chilled water through a process loop. The CGAF platform was a mainstay of Trane's commercial and light-industrial chiller lineup from the 1990s through the 2000s, commonly used in plastics manufacturing, semiconductor fabrication, food processing, printing, laser cooling, and general process cooling applications where a reliable chilled-water supply was required. The Intellipak control system provided integrated unit monitoring, fault diagnostics, and setpoint management — a significant feature for the era that made commissioning and troubleshooting straightforward for facilities personnel. These units are designed for rooftop or ground-level outdoor placement and connect directly to an existing chilled-water piping system, making them relatively straightforward to relocate and recommission. Because this class of chiller uses R-22 refrigerant (which is no longer manufactured for new equipment), buyers should verify refrigerant availability and charge status prior to start-up, and may wish to consider an R-22 reclaim/retrofit plan. A 20-ton air-cooled chiller of this type is appropriate for small-to-mid-scale process cooling loads and is commonly sought by facilities replacing failed units or expanding process cooling capacity.
