9.2.6 ELECTRIC DEFROST
A traditional defrost controller will power the heaters and keep them on until it receives a signal to
terminate based on time or a temperature cut out. One of the issues created with this approach is a
fogging effect. KE@ Evap’s electric defrost cycle pulses the defrost heaters to reduce fogging potential
and achieve reduced energy consumption.
The fans remain off until the defrost cycle is terminated and the drain time has elapsed.
