Trane Commercial Building Systems

Pre-engineered for efficient and cost-effective electrified solutions

Comprehensive Chilled Water Systems

Comprehensive chilled-water systems employ best practices in chiller plant design that align with current industry guidance for achieving high performance cooling, heating, and ventilation, all while reducing first cost.

Comprehensive Chiller-Heater Systems

Trane® Comprehensive Chiller-Heater systems, featuring electric heat pumps, provide cost-effective, energy-efficient, reliable cooling and heating, while reducing carbon emissions. Ideal for larger buildings, especially those with a central plant, these pre-engineered system solutions make electrified HVAC systems easier to specify and implement.

CoolSense® Integrated Outdoor Air Systems

The CoolSense® pre-packaged HVAC design system combines a dedicated outdoor-air system (DOAS) with chilled-water sensible-cooling terminal units to deliver a flexible, energy-efficient solution that enhances comfortable spaces and simplifies maintenance.

Intelligent Variable Air Systems

Trane Intelligent Variable Air systems simplify the design and implementation of systems that HVAC designers typically consider complicated and time-consuming. With new technologies and optimized controls, these systems are 20% to 30% more efficient than traditional multiple-zone VAV systems.

Thermal Battery Systems

Trane Thermal Battery™ systems are premier HVAC plants that provide a distributed resource for our changing grid. Their ability to store thermal energy enables your building to reliably modify HVAC operations to optimize for carbon reduction or energy cost savings.

Variable Refrigerant Flow (VRF) Systems

Regardless of the capacity, energy efficiency, functionality or performance-monitoring requirements, our VRF Systems Solutions, featuring Trane® / Mitsubishi Electric VRF Technology, are designed to exceed the comfort and sustainability goals established for commercial building projects.

Zoned Rooftop Systems

Ideal for small buildings, Trane® Zoned Rooftop Systems provide cost-effective options to increase comfort and energy efficiency, while simplifying operation and maintenance. These packaged systems make advanced functionality affordable and easy for non-technical users to operate.

Next Generation Refrigerants

The EcoWise® portfolio of products allow you to design lower environmental impact systems while simultaneously addressing your customer’s climate commitments and efficiency goals. Choosing the best refrigerant for each application should be based on a balance of safety, environmental impact and total cost of ownership. Let Trane's application experts guide you to the best refrigerant solution.

Chilled Water Systems: 50 Years of the Engineers Newsletter
The first-of many Trane Engineers Newsletters on chilled-water systems were published in 1973 with concentration on chilled and condenser system piping design. At that time, chilled-water systems had a constant-flow design. This began to change in the late 1970s as a new technology, the variable speed drive, was applied to chilled-water pumps. To educate the industry, “A Need for Variable Flow Chilled Water Systems” (1977), “Water Chiller (Control): Decoupler Variable Flow Systems” (1979), and “Chillers are Constant Flow Devices” (1980) were published. These articles provided background on primary-secondary (decoupled) systems which operated more efficiently and became common design practice for the next decade.
