Legend:

A = Fouling factors (m2 °C / kW)

B = Cooling capacity correction factor

C = Power input correction factor

D = EER correction factor

Table 3 - Air heat exchanger - Altitude correction factors

Legend:

A = Elevation above sea level (m)

B = Barometric pressure (mbar)

C = Cooling capacity correction factor

D = Power input correction factor

- Maximum operating altitude is 2000 m above sea level

- Contact factory in case the unit has to be installed at altitudes between 1000 and 2000 m above sea level

Table 4 - Minimum glycol percentage for low air ambient temperature

Legend:

AAT = Air Ambient Temperature (°C) (2)

A = Ethylene glycol (%) (1)

B = Propylene glycol (%) (1)

(1) Minimum glycol percentage to prevent freezing of water circuit at indicated air ambient temperature

(2) Air ambient temperature do exceed the operating limits of the unit, as protection of water circuit may be needed in winte

r season at

non-working conditions.
