The 4CX10,000D/8171 is identical to the 4CX5000A/8170 except for its rated plate dissipation. Its increased capability, resulting in a larger cooler, is most useful in linear applications where plate dissipation is generally the limiting factor. The larger cooler also allows the 4CX10,000D/8171 to be used in place of the 4CX5000A/8170 with cooler operation at any given air flow rate.
