Johnson Controls VAV Box Systems

vav box
  • Application flexibility meets a wide variety of facility air flow requirements

  • Superior flow measuring provides for lower minimum cubic feet per minute (CFM) values, which reduces energy costs and noise while maintaining comfort in the zone

  • Integrated DDC controller, pressure sensor and actuator – all factory mounted to a VAV terminal unit – reduces installation time

  • Seamlessly integrates into the Facility Explorer building management system

  • Advanced diagnostics increase reliability and reduce maintenance needs

Packaged VAV Box Systems

The Facility Explorer Packaged Variable Air Volume Box System provides an integrated VAV box with controls. You Get direct, closed-loop control specifically designed to deliver occupant comfort and installation flexibility. This pre-configured system with factory installed FX-PCV Programmable Controllers eliminates the coordination and difficulties associated with field mounting. These terminal units are specifically designed for precise air delivery throughout the entire operating range, regardless of the installed inlet conditions. Plus, these VAV boxes deliver quiet, efficient air flow.

The integrated FX-PCV controllers feature automatic self tuning algorithms to deliver optimal control with less wear and tear on the equipment. These controllers include a rich set of embedded and optional features, enabling you to quickly and simply build a control strategy based on VAV box type.
