A. Computer-controlled automatic defrost devices : advanced computer control technology. Defrosting precision temperature sensors, ensure that the machine is as low as 5 ¡ã C in the environment, despite the normal operation of dehumidification, is the most advanced and reliable automatic defrost devices make dehumidifier for the "all-weather" work capacity.

B. Mechanical temperature control defrosting devices : metal film memory of the temperature controller, not as precise temperature control defrosting, defrost performance is not stable enough. Some machines often occurs in about 8 ¡æ normal operation can be, but in some 13 ¡æ frosting on the situation stands, therefore, Defrosting device which is not accurate and reliable. Note : Some Type A dehumidifier in the design of machines installed relays, Timing will stop compressor (fans maintain continuous operation) waiting for the heat exchanger after the frost melted start functioning again, The so-called "regular defrost" actually is not automatic defrost devices, but only a timer switch.
