How To Choose Your Heat Exchanger?

 

Generally speaking, the size is ok when the wort can be cooled to fermentation temperature in 30-45minutes.

The plate heat exchanger we often used in craft field could be divided into two types:
Single stage heat exchanger and double stage heat exchanger. There is no difference in appearance between these two types.

But how to choose these two?

For single stage heat exchanger:
Cooled water is used as coolant of this kind of heat exchanger. It’s more efficient since the whole heated water can be recycled. And if there is unknown leakage on heat exchanger, the beer is just be diluted. But you need a cold liquor tank for cold water supply.

For double stage heat exchanger:
City water is used for first stage cooling and glycol water is used for second stage cooling. Much of the heat energy is wasted. Also the heated glycol water will affect the cooling of fermenters and brite tanks when it is circulated. What’s more, similarity, if there is unknown leakage on heat exchanger, beer will be polluted by glycol water.
 
So what would your choices be?
