11.4. HEATING CAPACITY AND INPUT
POWER
The heating capacity yielded and the input electrical
capacity in conditions other than
rated conditions are obtained by multiplying the
rated values (Ph, Pa) by the respective correction
coefficients (Ch, Ca).
The diagram allows you to obtain the correction
coefficients; corresponding to each curve,
the temperature of the hot processed water referred
to is reported, assuming a difference
in water temperature between the input and output
of the condenser equal to 5°C/10°F.

factors.
11.6. FOULING FACTORS
The performance levels indicated in table: ”
FOUL
ING FACTOR K*M
2
/ W ”
refer to conditions with
clean tubes, with a fouling factor = 1. For values
different from the fouling factor,
multiply the values in the performance table by the
reported coefficients.
