Unfortunately NO, you cannot use a GC4 Glycol Chiller with the T500 condenser.

The reason for this is because when the glycol enters the condenser the glycol will heat up to a very high temperature. It will then recirculate back into the glycol chiller at this high temperature (as it doesn't have enough time to cool down) which will cause malfunctions with your chiller because they do not have the efficiency suitable for this.
