Trane Technologies is introducing enhanced Modular Self-Contained (MSC) units to simplify HVAC installation and enhance building performance, minimizing installation disruption and maximizing building productivity. The MSC’s enhanced innovative design streamlines the entire process from delivery to startup.
“Trane's new MSC units are another example of how we are innovating to help current buildings upgrade to the most efficient technology while minimizing the disruption of the retrofit,” said Oakley Roberts, Vice President of Product Management, Commercial HVAC Americas, Trane Technologies. “Designed for rapid assembly, the units can be up and running within a 24-hour period, reducing downtime and improving building productivity. Our new MSC units can improve full load efficiency by up to 30% versus legacy systems.”
The updated Trane Modular Self-Contained (MSC) units simplify HVAC replacements in space-constrained environments. The modular design allows the system to be broken down into smaller, easily transportable sections, overcoming the limitations of traditional installations. The units are now available in capacities from 20 to 80 tons, with new 90–110-ton options available in April 2025.
Beyond simplified installation, the MSC units prioritize occupant comfort and operational efficiency. Variable-speed compressors and direct-drive plenum fans ensure quieter operation. Enhancing this performance is Trane’s new Symbio® 500 unit controller, which offers advanced features like remote connectivity, custom programming, and expanded communication options. These units also utilize low-GWP R-454B refrigerant and include factory-installed leak detection systems.
