Comfort Control - SEMCO’s unique comfort control makes it easy to adjust the airflow also allows for simplified system balancing and installation since all the nozzle sizes and capacities are built into every beam

The key to every chilled beam selection is choosing the proper nozzle size. The nozzle size determines the air pressure, velocity, throw, noise level and induction rate of the chilled beam. Controlling these variables in turn determines the cooling power delivered to the space.

SEMCO’s Comfort Control feature makes it possible to adjust the nozzle size on any active chilled beam, even after installation. The easy regulation of the capacity and air diffusion make it possible to adjust the beam to deliver optimum comfort to the space and then adapt to future changes in the space.

Using the patented control rails, the nozzle size can be adjusted by varying the size of the slot opening along the length of the supply air channel. The adjustable slot size permits different cooling performances from the same beam, as well as different air diffusion (four-way, two-way, one-way, or intermediate balance). Not only does this allow for simple adjustment to deliver the proper cooling power to the space, it also allows the discharge pattern to be balanced to direct the majority of the cooling power toward the load source, or the majority of the ventilation air toward the larger floor space to ensure proper cooling and ventilation comfort.

In addition, Comfort Control ensures the beam’s performance can be changed to match new space conditions without having to manipulate the primary airflow or the water loop.
