At the time of its manufacture, Trane’s XL 1800 air conditioning series consisted of three models ranging from 3- to 5-ton capacities. These discontinued units have cooling capacities ranging from 38,000 to 59,5000 BTU/hour and are capable of reaching up to 18 SEER.
The XL1800 features dual-scroll compressors that the manufacturer says allow for cost-effective, two-stage cooling. In addition, this unit is promoted for its “whisper quiet” operation, through the help of compressor sound insulators and a two-speed fan motor.
A baked on powder paint finish, corrosion- and weather-resistant screws, a protective top, and galvanized steel louver side panels help protect the unit from weather extremes and maintain the exterior appearance over time.
Additional feature include electrical and refrigeration components located on one side for easy service, a two-row spine fin coil for efficient heat transfer, and external braze fittings designed to ensure a leak-free installation.
