CROSS FLOW HEAT EXCHANGER Deluxe

A vertically mounted rectangular section duct with an opaque plastic front cover is connected at its lower end to the intake of a powerful variable speed fan. At the upper end of the duct is a bell mouth air intake. Air is drawn by the fan into the duct and past the heat exchanger accessory before being discharged from the fan. Learn about CROSS FLOW HEAT EXCHANGER manufacturers for optimal educational outcomes.. A pair of manometers allows measurement of the pressure drop across the intake from which the air velocity in the duct may be determined. Situated at approximately mid height in the front of the duct is an opening into which any of the various heat exchanger accessories may be located.
