Copeland 985-0109-00 Probe Refrigerant or internal valve set replacementThe Copeland 985 0109 00 is a specialized thermistor probe engineered for the Copeland Demand Cooling system, primarily used in low temperature refrigeration applications using R 22, R 407A, R 407F, or R 448A 449A. This discharge temperature sensor monitors high side heat directly at the source, signaling the injection valve to provide liquid refrigerant cooling when temperatures exceed safe operating limits.
