Single Channel

The SEC Spiral heat exchanger approaches the ideal in heat transfer due to a single channel for each side which eliminates distribution problems and reduces fouling.

The spiral channels enhanced by studs, induce turbulence which increase heat transfer efficiency.

True counter current flow permits close temperature approaches and temperature cross for heat recovery and interchangers.

The SEC compact Spiral heat exchanger is an assembly of two long sheets, usually separated by studs, wrapped to form a pair of concentric spiral channels.

Alternate edges are closed and seal welded. Covers on each side complete the Spiral. Connections are installed on the “shell” and covers to provide true counter current flow.

Specialized flow distribution is achieved using various manifolds, impingement plates and other techniques to minimize entrance and exit maldistribution.
