Table 2: Technical data – three-phase fans
“Old” units were delivered with three-phase fans as a standard, but it is possible to convert these fans into single-
phase motor by the mean of a capacitor. The characteristics of this run capacitor are given in table 2.
“New” single-phase kits can be used for retrofitting on units equipped with three-phase fans.
