Heat Pump Heating Performance

The TWA090K3AAA**BS01 provides heat pump operation for year-round heating and cooling. When matched with compatible indoor equipment, the heat pump condenser can provide primary heating operation, with supplemental electric heat available where supported by the selected indoor equipment. Trane's Odyssey heat pump systems are designed as matched split systems, so heating capacity and efficiency depend on the certified outdoor and indoor equipment combination.

87,000 BTU/h Cooling Capacity

The TWA090K3AAA**BS01 provides a nominal 87,000 BTU/h, or 7.5-ton, cooling capacity. The TWA090K3A configuration uses three-phase 208/230V electrical service and is part of Trane's 6- to 25-ton TWA commercial split-system product family. Trane's published electrical data identifies the TWA090K3A configuration with a 208-230V, three-phase compressor electrical supply and a three-phase condenser fan motor.

R-454B Refrigerant & Efficient System Operation

The TWA090K3AAA**BS01 is designed for R-454B refrigerant and POE oil. R-454B is a lower-global-warming-potential refrigerant used in Trane's current commercial split-system platform. Because R-454B is an A2L refrigerant, installation, service, refrigerant handling, and piping procedures must follow the applicable Trane documentation and current codes.

Commercial Split-System Installation Design

The split-system configuration separates the outdoor TWA090 heat pump condenser from the compatible indoor air handler or coil assembly. Trane's application documentation identifies TWA090K3A as a 7.5-ton nominal model with a single refrigeration circuit. For the TWA090K3A configuration, Trane's published application information identifies 1-1/8-inch horizontal and downflow suction-line sizing and 1-1/8-inch vertical-return suction-line sizing for the applicable TWA090K3A configuration. Refrigerant piping must be sized and installed according to the applicable Trane Odyssey application and installation documentation.

Controls & Comfort

The TWA090K3AAA**BS01 supports Trane control configurations intended for Odyssey commercial split systems. Depending on the matched indoor equipment and selected controls, the system can support conventional or communicating control arrangements. Actual control functionality, staging, supplemental heat operation, and system monitoring depend on the selected indoor equipment and control configuration.

Commercial Applications

The Trane Odyssey TWA090K3AAA**BS01 is designed for commercial split-system applications requiring approximately 7.5 tons of heat pump capacity. Its 208/230V three-phase electrical configuration and compatibility with commercial indoor equipment make it suitable for commercial buildings where a separate outdoor heat pump condenser and indoor air-handling system are preferred.

Service & Maintenance

The TWA090K3A platform supports application-specific accessories intended to simplify installation and accommodate different operating environments. Available accessory categories for applicable TWA units include isolation systems, service valve kits, low-ambient controls, communication interfaces, and expansion modules. Trane's commercial documentation should be consulted to select accessories compatible with the specific unit configuration and installation requirements.

Warranty

Warranty coverage for the TWA090K3AAA**BS01 should be confirmed using the current Trane Odyssey Limited Warranty documentation applicable to the equipment, installation, registration status, and application. Warranty terms can vary according to the equipment configuration and applicable warranty provisions.
