Alfa Laval Inc. Welded Spiral Heat Exchangers ALSHE Cond

The standard spiral heat exchanger design brings the advantages of ultra-efficient self cleaning effect, that maximizes uptime operation. A perfect fit for fouling duties! Self-cleaning The single-channel construction eliminates bypassing and reduces fouling. The turbulence of the fluid in the channel constantly flushes away any scaling or deposits as soon as they form. If fouling occurs, thus diminishing the cross section of the channel, the velocity increases and scrubs away deposits at the eaxct zone affected. Small space requirement The wrapped cylindrical arrangement of a minimiezed heat transfer surface results in an extremely compact unit. This compact design ensures lower installation costs. Easy access and maintenance The compact design provides easy access on the process side. High turbulence ensures a low-risk of fouling on the cooling side. Id cleaning is needed, chemical cleaning on the cooling side is very efficient because of the single channel construction. Applications The Alfa Laval ALSHE Cond spiral heat exchanger can be used as: Condenser Reflux condenser Reboiler Gas cooler Heater (even in presence of very large vapour or gas flows and/or very low pressure drop.
