Profile Arctica uses an Adaptive Defrost System which operates on an 8-hour minimal defrost cycle. This means
the defrost won't run until there has been at least eight hours of compressor run time. The maximum time
between defrosts is 60 hours.
ClimateKeeper2 operates on a 10-hour minimal defrost cycle resulting in even less defrosting than our
award-winning ClimateKeeper system. Because there are two evaporators, cycle run time is calculated only by
the freezer evaporator allowing even more time between defrost cycles. Less defrosting preserves the quality of
frozen foods longer.
Parallel vs. Serial systems
There are two different types of dual evaporator
systems in the U.S. today, the serial system and
the ClimateKeeper2 's parallel system.
A parallel system can operate each evaporator
independently, or both at the same time if needed.
This flexibility allows very precise cooling.
A serial system must operate both evaporators
simultaneously or only the freezer evaporator. It
can not operate the fresh food evaporator alone.
