4-Ton Single-Stage Cooling – Reliable Commercial Cooling

The Trane 5TTA4048A4 provides 48,000 BTUH of nominal cooling capacity to help maintain comfortable indoor temperatures during warm-weather operation. The outdoor condensing unit is designed for use with compatible matched indoor equipment and is part of Trane's 14 Single-Stage air conditioner platform. Depending on the matched indoor coil or air handler configuration, system efficiency ratings can vary.

ClimaTuff® Scroll Compressor – Dependable Cooling Performance

The ClimaTuff® scroll compressor provides the compression required for reliable cooling operation. The compressor incorporates internal over-temperature and pressure protection, a centrifugal oil pump, and a design intended to provide low vibration and noise. The 5TTA4048A4000A operates on 460V, three-phase, 60 Hz power, with a minimum branch circuit ampacity of 8.6 amps and a maximum branch circuit protection rating of 15 amps.

Spine Fin™ Coil – Efficient Outdoor Heat Transfer

The outdoor Spine Fin™ coil is designed to provide low airflow resistance and efficient heat transfer. The 4-ton model uses a 27.5-inch outdoor fan with a 1/5 HP motor. Louvered panels protect the outdoor coil on all four sides, helping provide durable construction for outdoor installation.

R-454B Refrigerant – Modern Refrigeration Platform

The Trane 5TTA4048A4 uses R-454B refrigerant and an expansion valve for refrigerant control. The outdoor unit is factory charged with the system charge required for the outdoor condensing unit, 10 feet of tested connecting line, and the smallest rated indoor evaporative coil match. The listed factory refrigerant charge for the 5TTA4048A4 is 6 pounds, 10 ounces. Proper system charge should always be verified according to the unit nameplate and applicable Trane charging procedures.

Split System Installation Design

The split system configuration separates the outdoor condensing unit from the indoor evaporator coil or air handler, providing flexibility for equipment placement and installation. The 5TTA4048A4 has 7/8-inch O.D. gas and 5/16-inch O.D. liquid service valve connections, with rated refrigerant line sizes of 7/8-inch O.D. gas and 5/16-inch O.D. liquid. Trane offers 25-, 30-, 35- and 50-foot refrigerant line sets. The installation literature specifies a maximum total refrigerant line length of 150 feet, including lift, and a maximum vertical change of 50 feet. For other line lengths, Trane recommends following the applicable Refrigerant Piping Application Guide or Refrigerant Piping Software Program.

Controls & Comfort

The system includes condenser fan and compressor controls along with low- and high-pressure switches. The 5TTA4048A4 is a single-stage cooling unit and can be matched with compatible indoor equipment and controls to provide the required cooling operation. As manufactured, the system supports cooling operation down to a 55°F outdoor ambient temperature. Optional low-ambient and evaporator defrost controls can be used for applications requiring cooling at lower outdoor temperatures, subject to the applicable matched-system requirements.

Commercial Applications

The Trane 5TTA4048A4 is designed for commercial and light commercial split-system cooling applications requiring a nominal 4-ton outdoor condensing unit and 460V three-phase electrical service. Its outdoor-rated construction, galvanized-steel cabinet, weather-resistant finish, and compatibility with approved matched indoor equipment make it suitable for a variety of commercial installations.

Service & Maintenance

The unit incorporates service-oriented refrigeration controls and accessible components to support installation and maintenance. A factory-supplied, field-installed liquid-line drier is standard. The compressor includes internal over-temperature and pressure protection, while the outdoor coil is protected on all four sides by louvered panels. Properly selected isolation is recommended when mounting the outdoor unit on a roof to help reduce sound or vibration transmission to the building structure. Available accessories include an anti-short-cycle timer, evaporator defrost control, rubber isolator kit, extreme-condition mounting kit, sound enclosure, seacoast kit, low-ambient kit, and service valve panel cover.
