Trane 3 Ton 14.3 SEER2 Commercial Air Conditioning Condenser | 460V 3 Phase - R454B - Single Stage

Reliable 3-Ton Split Air Conditioner for Commercial Applications with Durable Outdoor Construction

The Trane 4TTA4036A4 is a 3-ton commercial split air conditioner outdoor condensing unit designed to provide reliable cooling for commercial and light commercial applications. Combining a 3-ton outdoor condensing unit with a compatible indoor evaporator coil or air handler, this split system helps deliver dependable commercial cooling while providing flexible equipment placement and installation options. The 4TTA4036A4000A configuration is rated for 460V, three-phase, 60 Hz electrical service and uses a ClimaTuff® scroll compressor with R-410A refrigerant.

Key Benefits

• ClimaTuff® Scroll Compressor – Provides dependable compressor operation with internal over-temperature and pressure protection.
• Spine Fin™ Outdoor Coil – Provides efficient heat transfer with low airflow resistance for reliable cooling performance.
• Durable Outdoor Cabinet – Heavy-gauge galvanized steel construction and a weather-resistant powder-paint finish help protect the unit in outdoor applications.
• Quick-Sess™ Service Access – Provides convenient access to service areas and refrigerant connections for installation and maintenance.
• Flexible Split-System Design – Separates the outdoor condensing unit from the indoor coil or air handler, allowing greater flexibility in equipment placement.
• Internal Compressor Protection – High- and low-pressure and temperature protection helps safeguard the compressor during operation.
• Low-Ambient Cooling Capability – Supports cooling operation at outdoor temperatures below standard cooling conditions when the appropriate accessories are installed.
• Factory-Tested Refrigeration System – The unit undergoes line-run testing and is factory charged for the outdoor unit, tested connecting line, and smallest rated indoor evaporative coil match.

3-Ton Cooling Capacity – Reliable Commercial Cooling

The Trane 4TTA4036A4 provides nominal 3-ton cooling capacity to help maintain comfortable indoor temperatures during warm-weather operation. The outdoor unit is designed for operation with compatible AHRI-certified indoor air handlers and furnace coils. The system uses R-410A refrigerant and is designed to operate at outdoor ambient temperatures as high as 115°F.

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, as well as a centrifugal oil pump, while its design helps provide low vibration and noise. The 460V, three-phase configuration has a minimum branch circuit ampacity of 8 amps and a maximum branch circuit protection rating of 15 amps.

Spine Fin™ Coil – Efficient Heat Transfer

The outdoor Spine Fin™ coil is designed to provide low airflow resistance and efficient heat transfer. The condenser coil is protected on all four sides by louvered panels. The 4TTA4036A4 uses a 23-inch outdoor fan with a 1/8 HP motor to move air across the outdoor coil during cooling operation.

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 4TTA4036A4 uses 3/4-inch O.D. gas and 3/8-inch O.D. liquid refrigerant connections. Trane offers compatible 25-, 30-, 35- and 50-foot refrigerant line sets, while longer line applications should be designed according to Trane refrigerant piping guidelines. 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.

Controls & Comfort

The system includes condenser fan and compressor controls along with low- and high-pressure switches. Compatible thermostat configurations include cooling-only and heat/cooling thermostats with manual or automatic changeover. An optional evaporator defrost control can extend low-ambient cooling capability, including operation to 30°F when used with a TXV.

Commercial Applications

The Trane 4TTA4036A4 is designed for commercial and light commercial split-system cooling applications where a 3-ton outdoor condensing unit and 460V three-phase electrical service are appropriate. Its outdoor-rated construction, durable galvanized-steel cabinet, corrosion-resistant finish, and flexible matched-system design make it suitable for a range of commercial installations.

Service & Maintenance

The unit incorporates Quick-Sess™ service access, accessible refrigerant connections, and full coil protection to support installation and servicing. A factory-supplied, field-installed liquid-line filter-drier is standard. The refrigeration system includes low- and high-pressure switches, while the compressor provides internal temperature and pressure protection. Optional accessories include an evaporator defrost control, rubber isolator kit, extreme-condition mounting kit, seacoast kit, low-ambient kit, sound enclosure, snow legs, snow-leg extensions, and service valve panel cover.
