Topic: Re: What determines the maximum cooling temperature that is possible from a chiller?

If you are operating on a batch basis then you are correct that it will take longer to chill the batch of glycol.  The temperature which the chiller operates at is determined by the suction pressure of the compressor and the vapor pressure curve of the refrigerant.  Once you have determined the thermodynamic cycle for the chiller system, the operating temperature of the evaporator determines the minimum temperature achievable.
