8.7. FOR ΔT DIFFERENT FROM THE
RATED VALUE
The performances given by the techni-
cal data refer to ∆t 5°C.
Use table to obtain the corrective fac-
tors of the cooling capacity and input
power different than ∆t 5°C.
8.8. FOULING FACTORS
The performance levels indicated in the
technical data refer to conditions with
clean tubes, with a fouling factor = 1.
For other fouling factor values, multiply
the data of performance table by the
coefficients given.
