Under any situation requiring continuous operation, both we and PolyScience recommend that you don't run a chiller at more than 80% load. Continuous operation under maximum load could damage the condenser, rendering the chiller inoperable.   What fittings are on the chiller for the coolant inlet / outlet streams? PolyScience Benchtop Chillers have two internally threaded (0.5 inch ID NPT) fittings on the rear of the instrument housing for the process fluid connections. Two sets of 90° barbed hose adapters (0.5 inch and 5/8 inch) are supplied with the unit for connecting these fittings to the process piping.    How large is the internal reservoir in the PolyScience Benchtop Chillers? The reservoir is 0.7 gallons / 2.65 liters. All models have the same size reservoir.
