Plenum Pressure Controls


Plenum Pressure Controls Details

In a UFAD system the plenum pressure is controlled by modulating a supply damper or controlling the fan speed of a direct connected AHU. AirFixture has several styles of pressure controls to accurately measure the UFAD plenum pressure relative to the room pressure, including:

  • Ultra-accurate under floor pressure sensors with a range of +or- .10inwc(25pa)
  • Pressure sensors built into floor diffusers matching the style and color of primary cooling diffusers
  • Simple 0-10 v dc signal

I’m always worried about trying something radically different in our projects. What if it doesn’t go to plan? What if there’s something we haven’t considered? Those concerns were completely unfounded with UFAD. it was far less complex, and way easier to plan and install than a traditional system.
