Factors based on 2.35 GMP per water circuit. Specify GPM when ordering.

Table 1 indicates usual basic Unit Cooling capacities at conventional operating conditions which
can be modified for variations in Refrigerant Temperature and Sensible Heat Percentage by use
factors in Tables 2 and 3.

Heating capacities vary with Entering Air Temperature, Steam Pressures and Water Temperatures
and can be modified by factors in Tables 4 and 5, interpolating for related values within reasonable
range.
