The cabinet features a durable, powder‑coated finish, corrosion‑resistant fasteners, and Trane’s signature full‑louvered panel design that protects the coil while maintaining strong airflow. A composite base pan helps reduce vibration and operating sound, and the compact footprint allows for flexible placement in tight outdoor spaces.
