Coil
Patented Thermo-Flex™ coil design allows the coil to
“flex” during periods of defrost resulting in expansion of
the coil surface. By eliminating the possibility of wear at
critical stress areas, the integrity and longevity of the unit
are dramatically increased (Patent number 5,584,340)
Coil heater slots have been enlarged for easier
installation and replacement
Electric defrost models have fixed defrost termination /
fan delay and heater limit thermostats
Reliable nickel steel alloy defrost heater elements
Heaters are coil face mounted for easy access
