Counter Flow Heat Exchangers
VoltAire’s HTC Counter Flow series provides a narrower width to accommodate placement on smaller doors or equipment. It also offers a quieter design.
The counter flow cores allow design capacity to be achieved with heat exchanger depth and height, rather than cross flow cores, which generally require additional width to increase capacity.
Best yet, for outside plant facilities in residential or light commercial areas, the slower airflow and lower decibel axial fans improve noise levels greatly. The HTC line is available in 15, 20, 25, 42, and 90 watts per degree Fahrenheit and available in 48VDC, 115VAC and 230VAC.
