Trane–by Trane Technologies announced updates to its Precedent, Odyssey and Foundation lines of HVAC systems that help customers with buildings of all sizes embrace electrification and decarbonization. The company also released version five of its system design software, TRACE 3D Plus, with new capabilities engineers can use to design and validate projects with confidence and clarity.

“Whether modeling for decarbonization during design and validation, reducing complexity on the day of installation, or optimizing energy efficiency during operation, Trane’s updated software, all-electric systems and updated unitary models help to empower owners to create the right solution for their building,” said Dave Molin, vice president of Trane Product Management, Equipment, Controls and Digital.

Continuing its introduction of the next-generation Precedent portfolio, Trane has released new standard and high-efficiency Precedent heat pumps in 12.5- to 25-ton capacities. The Precedent line meets the U.S. Department of Energy (DOE) 2023 energy efficiency standards. All next-generation units released to date are now available in a high-efficiency model that exceeds those standards by 25% or more.

Trane’s all-electric Precedent heat pump is among the first packaged rooftop heat pumps in the industry available in a 25-ton capacity, the company said. Convenient characteristics simplify service and installation, such as hinged access to the control panel, color-coded wiring, keyed connectors and no fan belts to adjust or replace. It arrives ready to install, and most replacements don’t require a curb adapter.

Trane has equipped all Precedent models with Symbio® 700 controls so owners can immediately enjoy the benefits of digital connectivity. Symbio 700 is a user-friendly onboard interface to optimize system performance, helps to improve serviceability, and facilitate unit connectivity and future enhancements. Its intuitive user interface displays system alarms and diagnostic reports building owners can use to troubleshoot. Use the free Symbio® Service and Installation Mobile App for simplified commissioning and troubleshooting. Symbio integrates with common building automation systems (BAS) and open standard protocols.

When rooftop installation isn’t an option, a Trane Odyssey spilt system delivers up-to-date energy efficiency, meeting DOE 2023 standards. Split systems provide the same high-performance heating and cooling of a packaged rooftop system but allow engineers and contractors to work around unique building designs such as glass ceilings or pitched roofs or code and service limitations.

The Odyssey’s exceptional energy efficiency is realized by its Symbio 700 controller, now standard, and a new multi-speed air handler that can be configured for two-stage or single-zone VAV or Variable Volume Zone Temperature (VVZT). It’s available with several indoor and outdoor compressor and condenser options, including dual-compressor and dual-circuit models, so technicians can service either compressor without shutting down.

Trane’s Foundation rooftop systems are available in a broad range of tonnages (3-25 tons) and have a footprint designed for quick and easy retrofits or unplanned replacements without the cost or hassle of a curb adapter. Foundation systems with capacities of 15 to 25 tons have been updated to meet the DOE 2023 efficiency standards, and 7.5 to 12.5 tonnages will be released in the first quarter of 2023. Foundation units in the smaller 3- to 5-ton capacities already comply with the new standards.

With the Foundation line contractors, building owners, and facility managers operating small-to-medium buildings can save up to $1,500 on installation without the need for a curb adapter. In addition, mindful design touches such as colored and numbered wiring and single-side service doors keep service and maintenance quick and economical. It can be configured in the field for horizontal or vertical airflow.

Trace 3D Plus design and analysis software is now available in version five, so engineers can quickly and precisely model HVAC systems. With version five, engineers and specifiers can move from the project plan to load design to energy and economic analysis, all in the same project file and interface.
