Semco system

A trace air system uses a series of boosters employing a pressure regulator and a check valve. The Semco systems is depicted in Fig. 6. Dynamic Air incorporates a similar concept controlling the air volume rather than the pressure.

What Beeler did not yet grasp was the very crucial role that a Semco Pinnacle Primary Ventilation System would play in the chilled beam application. The Pinnacle unit utilizes advanced heat wheel technology to dehumidify and precondition supply ventilation air — an important part of the puzzle since chiUed beams handle sensible load only, not latent (humidity) loads. The combination of the two technologies has been successfully applied in facilities throughout the U.S., including the South. 

To remove all doubt that the combined systems could meet the university s needs, Semco invited Beeler and his staff, along with TME to the Semco facility in Columbia, MO where they could speak with the manufacturer s engineers and actually see and experience for themselves how the two technologies worked together.
