■ Characteristic for model BIII and BX
● Independent humidificatifier ensures humidity control.
● 30 periods of programs LCD controller, gradient running.
● Easy operation: running with data set and time set, and automatic shutdown.
● Special function key for temperature setting.
● Auxiliary menu makes over-temperature alarm, deviation adjust, and menu buttons lock come true.
● Forced air convection makes the temperature more uniform.
● Power outage protector: automatic recovery to previous normal status after power on.
● Compressor overload protector.
● Patent No.: 201320059701.3
■ Special characteristic for model BX
● Shelf-check of the circuit, sensor fault alarm, and superior and inferior limit over temperature alarm.
● Intelligent refrigeration and defrosting system.
● Watchdog timer
● Over temperature protector.
