Trane commercial equipment upgrades were recently announced by Trane Technologies. They included redesigns for the Precedent Rooftop Unit line, updates to some of their split and variable air volume products along with new indoor unit styles for the Trane/Mitsubishi Electric HVRF product line.
This is why K & D Mechanical uses Trane equipment. Because they are always on the fore front of innovation. We’re going to give you an overview of these upgrades and new equipment.
Doing our part to curb global warming
VP of Product Management Oakley Roberts said, “Trane is making it easier for building owners, engineers, and contractors to help make headway in all these areas (decarbonization, refrigerants for low global warming) with additions to the market-first all-electric HVRF, more rooftops and split systems that are equipped with low-GWP refrigerants, and the completion of the next-generation Precedent line that help consistently deliver on expectations.”
All-electric hybrid VRF line additions
Trane commercial equipment upgrades includes adding two families of indoor units to the Trane/Mitsubishi Electric HVRF (Hybrid Variable Refrigerant Flow). The only all-electric hybrid VRF unit on the market.
How does HVRF work?
The HVRF system uses a combination of refrigerant to connect the outdoor units to the Hybrid Branch Controller (HBC) and water to connect the HBC to the indoor units. This 2-pipe system fuses the advantages of VRF and hydronic chillers into an all-electric heat pump that heats/cools while reducing refrigerants in the whole system.
In addition to the existing ceiling-concealed indoor units, there are now ceiling cassettes and wall-mounted options. These new styles give installers (like us) more flexibility during installations to better match the esthetics and design of your commercial space.
Multi-zone capability
This system helps any owner who has a multi-zone commercial building that needs to be able to set various rooms at different temperatures. The end result? Hitting your sustainability goals through electrification and still meeting ASHRAE 15 refrigerant requirements.
This will be helpful on retrofits or new hotels, multi-family complexes, offices, etc. You get the benefits of VRF while managing life cycle cost and system efficiency.
Electric HVRF indoor units’ feature
- 4-way ceiling-cassette-range of capacities from 4,000 to 15,000 BTU/H
- 4-way ceiling-cassette in 4 ranges-6,000-48,000 BTU/H
- Wall-mounted units ranging from 4,000-30,000 BTU/H
- All indoor units feature hydronic coil
Precedent RTUs offer new features
These light commercial packaged rooftop units now have low-GWP R-454B refrigerant. This means small commercial offices, restaurants, warehouses, and government buildings can operate more sustainably.
- Better system performance thanks to the Symbio 700-unit controller with onboard interface & app
- Reduced carbon emissions with all-electric heat pump & hybrid dual fuel options.
- Optional modulating hot gas reheat for dehumidification & temp stability.
- Faster install as new modular design houses all components in 1 cabinet.
- Easy service with new hinged control panel door, color-coded wiring, keyed connections & no belts to replace.
Precedent is the most complete, consistent line of light commercial packaged RTUs coming in capacities from 3 to 25 tons. With 3 levels of efficiency ratings-standard, high and ultra-high eFlex-there’s one for every budget.
Foundation RTUs upgrades
These latest changes to the Foundation line will make it easier and faster to install these units, making sure they work more efficiently from day one.
- Factory-installed leak detection systems for faster installation.
- Symbio 700-unit controls are standard in 15-25-ton capacity units for improved performance.
- R-454B refrigerant will be available in 7.5-12.5-ton capacities in early 2025.
Trane has a name change
Trane’s RAUJ models are now called IntelliCore Large Split Systems. With these systems you can lower operational costs and still meet sustainability goals. They can be installed on the ground or combined with air handlers, chillers, and climate chargers when RTUs won’t work.
Large, air-cooled condensing units feature
- Factory-installed Symbio 800 controller for better system monitoring & connectivity.
- Low-GWP R-454B refrigerant meets environmental regulations.
- New factory-installed options: unit disconnect switch, powered or non-powered convenience outlet, high short-circuit current rating (SCCR)
Odyssey split systems
Another option when RTUs aren’t feasible, Odyssey split systems now include features to make them more flexible and convenient to meet decarbonization efforts.
- Now it uses low-GWP R-454B refrigerant.
- Factory-installed leak detection systems
- Symbio thermostat control is easier to wire for faster install.
- Optional-pair building automation system with Symbio controller.
VariTrane VAV series is redesigned
The VAV (variable air volume) series have been upgraded and are less noisy at full and part- load. Quieter operation means they are ideal wherever acoustics are essential, like schools, healthcare facilities or commercial buildings.
- Better humidity control
- Improved indoor air quality
- Exceptional energy efficiency
In short, they work with Trane building automation systems (BAS) for better performance.
As you can see, Trane continues to be innovative by including features that help with decarbonization and sustainability. Contact K & D Mechanical, Inc. if you want to learn more about Trane commercial equipment upgrades or get an estimate on your new project.
