Plate Frame Heat Exchanger

For some applications, a separate heat exchanger is required to work with the chiller to isolate the water or process loop from the chilled water/glycol loop.   Some common reasons for this are:

* Process Water needs to get below ~ 40F.   Straight water cannot flow directly into a chiller below these temps.  This is because the refrigerant temps in the chillers evaporator/exchanger will be ~ 15 to 20 degrees F colder than the desired the temperature of the water.   Freezing and potential rupture of the chillers evaporator would result.  The chiller loop would be a glycol concentration going through the glycol side of the heat exchanger. 

* the process water/fluid that needs to be cooled is dirty, and a heat exchanger isolates the chiller’s water/glycol loop from the process loop.

* Brewery or beverage applications.

The Plate Frame Heat Exchanger is popular option as it’s cleanable and expandable.
