6.1.7 Compressor cooling type
Smaller compressors, with relatively low power motors, can be used in a static cooled arrange-
ment. Compressors with higher power motors require forced ventilation. Some compressors in
the E and T series are also available with an oil cooler. This oil cooler is a coil positioned in the
lower part of the housing immersed in the oil sump. (See “2.7 - COMPRESSOR COOLING
TYPES”).
IOW If the compressor was designed to be fan cooled in an enclosure, it will come with a fan and/or an oil cooler coil.
Have you ever seen (in person) a refrigerator or a/c unit that came with a fan? I have never seen one and I have seen many, many units.
