This is the login for Trane® Connect™ and other Trane® commercial applications. Trane® Connect™ is our secure, cloud-based customer portal to access your building systems to remotely monitor and manage building systems, and conduct routine maintenance.
Thermafit® modular chillers are designed to fit through standard doorways and onto freight elevators. As the most versatile air-cooled split system in the Trane product line, model MAR boasts an easy to install, flexible design.
Designed for every-season cooling
ECM variable speed condenser fans make cooling operation possible and energy efficient at ambient temperatures down to 0ºF. Flooded condenser allows for low ambient cooling down to -20ºF.
Improve occupant comfort with sound-sensitive engineering
The variable speed fan and motor assemblies run quietly, without creating distracting and disruptive noise.
No glycol required
Since the evaporator is located indoors, you can eliminate the requirements for freeze protection associated with outdoor units—including glycol, draining the system, heat trace, and running pumps throughout the winter.
