When To Use A Plate Type Heat Exchanger

In any type of system where there is the need to heat or cool liquids, a heat exchanger is an effective component if one liquid is coming into the system hot or warm and one liquid that is cooler. The heat transfer between the two liquids at different temperatures is provided through the exchanger, which is an energy efficient way to address the need to raise or lower temperatures.

A plate type heat exchanger is a good option for many types of operations and applications. It is particularly effective for sanitary processing as it is very long lasting and durable, offers a significant surface area for the heat exchange, and can be used on most types of media from highly viscous to liquid.

Pressure Considerations

While a plate type heat exchanger is effective for most sanitary processes, it is ideally suited when the system pressure is low to moderate. High pressure systems require heat exchangers that are built with fewer joints and components to prevent the risk of leaks between the two liquids within the system.

Size Considerations

Thanks to effective design options, a plate type heat exchanger can be configured to meet most processing system size limitations. However, these systems use stainless steel plates with rubberized gaskets between, and the plates are mounted in a frame. The surface area and the size of the plates determine the efficiency of the system, so very extremely small areas, this may not always be the most effective choice.

The plate type of exchanger is ideal when there is both a large or a very small temperature difference between the two liquids. This is an advantage to these types of systems, and one of the reasons they are so popular in the sanitary process industry.
