Retrofitting

Internally lined ductwork can become quite dirty after many years of steady use. This increases the resistance to air flowing through the ducts, and reduces the volume of air that the supply-air fan can move […]

Many facilities are too small to have their own chiller. Instead, they have a number of packaged DDX units. These have unique energy-saving opportunities, either in retrofit projects or the modification to the existing equipment. […]

Condenser water is pumped to a cooling tower where it’s sprayed out of the top. Percolating downward across honeycombed fill, against the forced airflow upward caused by the fan, the atomized water droplets are cooled […]

Chillers transfer heat collected from the building loop to the cooling-tower loop. This warm water is pumped to the tower where its temperature is lowered by evaporative cooling; then it’s circulated back through the chiller. […]
