In the race to decarbonize commercial buildings while maintaining optimal indoor environments, Trane has introduced an innovative solution that’s changing the game. The Trane® Thermafit® Air-Source Modular Multi-Pipe Unit Model MAS represents a significant leap forward in building climate technology, offering an all-electric, all-in-one system that delivers both sustainability and exceptional performance.
The Thermafit® Model MAS eliminates the traditional approach of separate heating and cooling systems. Rather than relying on fossil fuel boilers in the basement and chillers on the roof, this modular unit provides both heating and cooling functions in a single outdoor solution. Starting at 30 tons (433 MBH) and expandable to an impressive 300 tons (4330 MBH), the system offers remarkable flexibility to meet diverse building needs.
What truly sets the Model MAS apart is its triple-mode operation capability. The system can provide cooling, heating, or simultaneous heating and cooling, adapting dynamically to changing building requirements. This versatility makes it ideal for buildings with varying climate control needs throughout different zones or seasons.
Unlike many electric heating solutions, the Model MAS delivers reliable performance even in extreme conditions. Lab-verified to provide dependable heating in outdoor ambient temperatures as low as 0°F (-17°C), the system can produce hot water temperatures up to 140°F (60°C). This exceptional cold-weather capability comes from its vapor injection scroll compressor, which extends the operating range for water temperatures around 130°F (54.4°C) even in frigid 0°F (-17.8°C) outdoor conditions.
The Model MAS doesn't just replace traditional heating and cooling systems – it dramatically improves upon them. The system is 8.2 times more energy efficient than other forms of electric heating, offering superior part load efficiency with 5% to 17% turndown capability. Its variable flow chilled and hot water loops further enhance system efficiency, reducing energy consumption and operating costs while minimizing environmental impact.
Reliability was clearly a cornerstone in the design philosophy of the Thermafit® Model MAS. The modular architecture eliminates single points of failure that plague traditional systems, supporting continuous operation even when maintenance is required. Each module in a bank can operate independently in different modes, allowing the system to handle unbalanced heating and cooling loads simultaneously – a feature that sets it apart from competitors.
For example, a bank of three modules can operate in three different modes simultaneously, providing exceptional flexibility to meet varying demands across a building. This genuine redundancy ensures that comfort is maintained throughout the facility regardless of changing conditions.
Whether for new construction or retrofitting existing buildings, the Model MAS offers remarkable integration flexibility. No cooling towers, geothermal systems, or complex infrastructure are required. The system can be easily incorporated into diverse building types – from small offices under 100 tons to large commercial facilities or campus environments.
The modular design supports growth alongside business needs, allowing capacity expansion without requiring complete infrastructure overhauls. The user-friendly touchscreen interface provides straightforward control, while optional cellular connectivity enables remote monitoring and management. The system can also connect to any building automation system, including Trane Tracer® SC+.
Beyond its environmental benefits, the Model MAS delivers strong financial returns. Its energy efficiency significantly reduces operational expenses, while the modular design minimizes costly downtime and repairs. The ease of integration reduces installation time and costs, further enhancing the overall return on investment.
As commercial building owners and operators face increasing pressure to reduce carbon footprints while maintaining comfort and managing costs, the Trane® Thermafit® Air-Source Modular Multi-pipe Unit Model MAS offers a compelling solution. By providing exceptional performance, remarkable flexibility, and industry-leading efficiency in an all-electric package, it represents a significant step forward in building climate technology.
For those seeking to future-proof their facilities while enjoying immediate operational benefits, the Model MAS stands as a testament to Trane's commitment to innovation and sustainability in the built environment.
