Get industry-leading energy efficiency with Trane® MSC

How good? Trane MSC is 35% more energy efficient at full load (EER) compared to a typical 25-year-old unit, and delivers industry-leading part load performance (up to 20.8 IEER). Talk about a step up. System includes:

  • Variable speed compressors
  • ECM plenum fans
  • Double-wall foam panels
  • Trane UC600 controls

Designed for fast assembly – typically within 24 hours

Think building blocks. Key components of the system are in engineered cassettes for easy shipping and transport. Once everything arrives the system is assembled and commissioned in the mechanical room – fast. So the system can be back up and running within a 24-hour period.

  • Each cassette fits through standard doorways, freight elevators
  • Assembled system footprint is as small or smaller than existing unit footprint
  • Evaporator cassette breaks down to move coil and cabinet structure into building

Trane pre-fab engineering is the key

The innovative cassette design offers the most adaptive self-contained footprint and breakdown available. Trane MSC cassettes are the smallest sections available in the industry for easy navigation through a building, incorporating many features for faster assembly:

  • Brazed circuit connections
  • Color-coded pluggable connectors
  • Self-leveling connectors
  • Victaulic® water pipe connectors
  • Ready-to-install wiring harnesses. 

BACnet-ready Trane UC600 digital controls provide easy set-up, scheduling and reporting

Trane MSC includes configurable and fully programmable Trane UC600 controls and the TD7  color display.  The display’s touch screen interface makes setup, scheduling, and management of the Trane MSC system easy. Includes custom, diagnostics, and service test mode menu keys. Connect to BAS with the open-standard BACnet EIA-485 Token Passing building automation.
