Model SWUD

Water-Cooled Self-Contained Units


Model SWUD

Water-Cooled Self-Contained Units

Key Features:

  • Available in 20–110-ton capacities
  • Up to 28% smaller footprint than our legacy units
  • Increased energy efficiency, on average 30% higher (full load) than our legacy units
  • Uses next-generation, low-GWP R-454B refrigerant with factory installed leak dectection system
  • Can be integrated into a Tracer® SC+ BAS using its factory-installed Symbio® 500 controller

Easy installation, smaller footprint.

The one-piece cabinet models drop into place and occupy a footprint that’s up to 28% smaller than our legacy product. For retrofits, we offer a modular design with components that can fit through a doorway and be assembled in place. Fully double-action hinged access makes our SWUDs easier to service over their lifetime.


Trane’s new energy efficient one-piece SWUDs are compliant with regulations mandating environmentally friendly refrigerants in all new packaged units by January 1, 2025. The factory-installed leak detection system offers increased safety and peace of mind. 

Energy efficient, with lower first costs

Our redesigned SWUD delivers improved full-load efficiency on average 30% higher than our legacy units. Because it’s a single-piece unit with straightforward installation, you’ll save on first costs. Over its lifetime, features such as double-wall foam-insulated panel construction and factory-installed Symbio® 500 controller enable you to save on energy costs well into the future.

Quiet operation with improved IAQ

Built with MERV 8 or 13 filters, 1” foam-injected double-wall panels and standard ECM fans, our SWUD delivers high indoor air quality while operating unobtrusively in the background.
