Glycol Saving

In many regions, the temperature in winter usually drops below 0°C/32°F.  In order to get lower temperature, glycol, as a lower-temperature intermediate, is used in systems with outside piping in this condition and PHE can be installed as a glycol saver.

In cases where the dry liquid cooled condenser is situated far away from the chiller and glycol is used, the amount of glycol that has to be added to the system is high and so is the cost. An intermediate PHE will minimize the glycol circuit, thus acting as a glycol saver and cutting expenses.
