Zusammenfassung:A coil on tube heat exchanger is provided that uses multiple parallel helical coil tubes to limit liquid pressure losses while providing similar performance and production times to previous coil and tube designs. Two or more coil tubes are wrapped together around a center tube in a helical fashion, permitting the heat exchanger to be used in a counter-flow, or contra-flow, implementation. Use of the heat exchanger includes flowing a first liquid, such as waste water, through the center tube and flowing a second liquid through the plurality of channels. Embodiments of the present invention provide reduced pressure loss, higher performance and are generally faster to manufacture than prior heat exchangers.
