VariTrane™ Single Duct


VariTrane™ Single Duct

Single-duct terminal units control the volumetric flow of supply air to the space to maintain the zone temperature at setpoint. 

Product Overview

These units are generally applied in cooling-only VAV zones that require no heat during occupied hours. If local zone heat is necessary it can be provided either remotely (for example, perimeter heat) or by terminal reheat (either electric or hot water coils).


  • Interlocking panel design provides the most rugged VAV unit available.
  • Metal encapsulated edges limit fiberglass insulation erosion into the airstream.
  • Averaging flow ring sensor accurately measures airflow at any inlet duct condition.
  • Pneumatic, electronic, or digital controls available.
  • Compatible with most controllers for field or factory installation.
  • Digital controls allow Tracer® building management system interface for Integrated Comfort™ systems (ICS) capability.
  • Cooling only (VCCF), hot water reheat (VCWF), or electric reheat (VCEF) units available.
