Blue fin. In summer, the Hydrophilic Aluminum fin of the evaporator can make the condensed
water flow freely between the fins and improve the cooling efficiency. In winter, it can improve
the heating efficiency by accelerating the defrosting process by the Hydrophilic Aluminum fin of
the condenser.                                                                                                                                                                                                                                                                                                                                                          
Intelligent defrosting ( in heating type) In winter, CPU of AUX air-conditioner under the heating
mode will defrosting completely according to tube temperature.
