New From Trane 2024Q3

Trane has finished updating the next-generation Precedent portfolio, making it the industry’s most complete and consistent line of light commercial packaged rooftop units. Features and available options are uniform across the entire Precedent portfolio, and all units ship with low-GWP R-454B refrigerant to help small commercial offices, restaurants, schools, warehouses, and government buildings operate more sustainably.

Precedent units come in a full range of capacities from three to 25 tons, efficiency ratings including standard, high, and ultra-high eFlex™, and heating types including gas/electric, electric/electric, heat pump, and hybrid dual fuel.

All Precedent units will now offer:

• Enhanced system performance, connectivity, and serviceability via the onboard Symbio® 700 unit controller featuring an intuitive onboard interface and app for start-up and servicing capabilities.
• Reduced carbon emissions with all-electric heat pump and hybrid dual fuel options.
• Dehumidification and temperature stability with optional modulating hot gas reheat.
• Quicker and easier installation with a packaged unit that houses components in one cabinet as well as a new modular component design that simplifies service, including a new hinged control panel door, color-coded wiring, keyed connections, no belts to replace, and common components across the product line.

Trane Foundation® Rooftop Units are transitioning to low-GWP R-454B. The units will include factory-installed leak detection systems, as required, to provide contractors and engineers peace of mind knowing the rooftops will operate effectively on day one, helping to save time and costs associated with installation in the field. In addition, large Trane Foundation Rooftop Units with 15- to 25-ton capacities will ship standard with Symbio 700 unit controls to improve performance and ease installation.

Foundation units in 7.5- to 12.5-ton capacities will be available with R-454B refrigerant in early 2025. 

Trane has updated its RAUJ models, now branded IntelliCore^TM Large Split Systems, to help building owners reduce operational costs and meet sustainability goals. Whether installed on the ground or in combination with other equipment such as air handlers, chillers, and climate chargers, IntelliCore Large Split Systems can be used in many applications when a rooftop unit is not feasible.

These air-cooled large condensing units have been improved to offer:

• Factory-installed Symbio 800 controller for enhanced system monitoring, performance, and building connectivity.
• Low-GWP R-454B refrigerant that meets environmental regulations.
• New factory-installed options, including unit disconnect switch, powered or non-powered convenience outlet, and high short-circuit current rating (SCCR), eliminate the need and cost of third-party installation.

A cost-effective heating and cooling solution for situations when a rooftop unit is not feasible, Odyssey^TM Split Systems include new features that help provide convenience and flexibility to help support decarbonization efforts. The systems have transitioned to low-GWP R-454B refrigerant and include factory-installed leak detection systems as required.

Odyssey Split Systems now come standard with Symbio thermostat control that has simplified wiring for easier and faster installation. Building stakeholders seeking to benefit from a building automation system (BAS) may choose to pair optional communication capabilities with the Symbio 700 controller as well.

Trane has added design enhancements to the VariTrane® VAV Series fan-powered terminal unit to provide superior acoustics compared to its predecessor. Equipped with an improved suppressor integral attenuator, the units help reduce noise in occupied spaces at full- and part-load. This upgrade makes the units ideal for applications where acoustics are essential, including commercial real estate buildings, healthcare facilities, and K12 schools.

Commonly used in commercial buildings, these terminal units match heating, ventilation, and air conditioning supply to localized demand to provide passive humidity management, help improve indoor air quality, and deliver exceptional energy efficiency. Its pre-programmed, yet customizable, control sequences work in conjunction with Trane building automation systems to enhance VAV performance.
