New Thermafit® Model MAS All-in-One Multi-pipe Heat Pump Provides 8.2 Times More Efficiency than Other Forms of Electric Heating

Trane – by Trane Technologies (NYSE: TT), a global climate innovator, today introduced the Thermafit® Air-Source Modular Multi-pipe Model MAS, a heat pump that produces cooling in the summer, heating in the winter, or simultaneous heating and cooling when both are required. The Thermafit Model MAS helps give contractors and engineers the option to eliminate or reduce the need for traditional, fossil fuel boilers and owners new solutions to decarbonize buildings through the electrification of heating.

Trane has also released an improved Deluxe Sound Package for the Trane® Axiom™ Horizontal and Vertical Water Source Heat Pumps (WSHPs) to help improve occupant comfort and updates and improvements to the Tracer® SC+ Building Automation System (BAS).

Flexible, Reliable, and High-Performing – the Thermafit Model MAS

The new Thermafit Model MAS is an all-in-one air-source modular multi-pipe heat pump with advanced logic to independently control each module’s mode of operation – cooling, heating, or heat recovery. It responds to varying building loads throughout the day and year, resulting in performance that is 8.2 times more energy efficient than other forms of electric heating.

“The Thermafit Model MAS may be the only piece of HVAC equipment a building needs because it can do it all – act as a chiller to cool the building, as a heat pump to heat the building, or as a heat recovery unit to deliver simultaneous heating and cooling,” said David Molin, Vice President of Trane Product Management. “Building stakeholders developing or implementing decarbonization, sustainability, or Environmental, Social, and Governance (ESG) initiatives may find that the exceptional system design of the Model MAS is a great fit for buildings today and the world of tomorrow.”

Featuring a flexible, compact, modular design, building engineers can easily apply the MAS to new or existing systems, and contractors can install and maintain it without the complex infrastructure that is common with water-cooled or geothermal systems. Notable features include:

  • 30-ton (433 MBH) modules can be banked together with up to 10 modules for larger capacities or future expansions (up to 300-ton bank/4330 MBH heating).
  • Hot water temperatures up to 140 degrees Fahrenheit (60 degrees Celsius).
  • Vapor injection scroll compressor with advanced defrost capabilities for cold climate operation.
  • A redundant, modular design eliminates single points of failure to support continuous operation. 
  • Next-generation, low-GWP refrigerant R-454B.

Redesigned Deluxe Sound Package for Axiom Horizontal and Vertical WSHPs

New Symbio Unit Controllers for Air Handling Systems and Water Source Heat Pumps Deliver Enhanced Connectivity

Because Trane Axiom Horizontal and Vertical Water Source Heat Pumps help contribute to carbon-reducing efficiency, they are ideal for multi-tenant structures. They are also commonly placed near occupied spaces. A new and improved Deluxe Sound Package is now available from Trane as a factory-installed option on standard and high-efficiency units to help increase occupant comfort. One of the quietest WSHP units available, testing validates that with the deluxe sound package, the Axiom Vertical and Horizontal Water Source Heat Pumps operate up to five decibels more quietly than units without the package installed. The package includes sound-absorbing compressor blankets, mass-loaded vinyl sound barriers, and two-inch-thick insulation on its cabinet panels.

Enriched Tracer SC+ Supports Equipment Controllers of the Future and Yesteryear

Tracer SC+ Front

Tracer SC+, Trane’s powerful building automation system that integrates data from HVAC equipment, has been updated with improved controls features that enhance system operation and increase productivity for building management teams. The latest release includes:

  • Broader support for buildings of the past, present, and future, with protocol communication compatibility for legacy Trane equipment and equipment from other OEMs.
  • Enhanced chiller plant control that helps optimize rotation, staging, and sequencing of multiple chillers to accommodate dynamic building loads while maximizing chiller life and helping to improve efficiency, as well as new application configurations valuable for large chiller plants.
  • Updated cybersecurity features and enhancements, including support for 802.1X authentication.

Tracer SC+ integrates building equipment through a simple communications bridge so facility managers can connect their buildings, be more responsive to occupants, and set new standards for sustainability. Built on a foundation of industry-standard open protocols, including BACnet, LonTalk, and Modbus, it supports Trane and non-Trane equipment from all generations so building owners and managers can align sustainability with profitability.

Buildings Won’t Know the Difference, But the Planet Will

Trane Transitions More Commercial HVAC Systems to Low GWP Refrigerants

 

As of January 1, 2025, all commercial chillers for comfort cooling and heating, packaged and split system HVAC units must ship with Low Global Warming Potential (GWP) Refrigerants to meet the U.S. Environmental Protection Agency’s Hydrofluorocarbons (HFC) phase-down requirements.

At Trane, we believe performance and sustainability can coexist. Transitioning to low-GWP refrigerants is one of the most effective decarbonization strategies for commercial buildings. Trane is quickly transitioning its product lines, so our customers have the solutions they need to successfully comply.

Trane Adds Factory-Installed Leak Detection Systems to Meet Safety Standards

According to safety standard UL60335-2-40, ducted HVAC systems with more than 3.91 pounds of R-454B refrigerant charge must include one or more refrigerant detection sensors. Trane is adding factory-installed leak detection systems to models with more than 3.91 pounds of refrigerant charge. In addition, those systems will be equipped with Building Automation Systems (BAS) points so building engineers can use the integrated Symbio® Controller to detect and mitigate leaks.

Trane has updated the following product lines with R-454B refrigerant and standard factory-installed leak detection system on models with more than 3.91 pounds of refrigerant charge:

“Factory-installed leak detection systems help give contractors and engineers peace of mind, save time and money by not having to install leak detection systems in the field, and help give them confidence that low-GWP systems are operating safely and efficiently on day one,” adds Molin.

More Trane Chillers/Chiller Heat Pumps Now Available with Next-Generation Refrigerant

After starting the transition over a decade ago, Trane has converted additional chillers and chiller heat pumps to low GWP refrigerants. The following product lines changed over in July 2024:

  • Trane Air-Cooled models ACS, ACX, and CGAM are available with R-454B refrigerant.
  • Trane Air-Cooled model ACR and Thermafit® Modular-Unit model MWC with High Temperature Heat Recovery is available with R-513A refrigerant.
  • Thermafit® Modular-Unit Chillers models AXM, WXM, MWC, and AMC are now available with R-454B refrigerant.
