Safety Protection | Features include self-tuning function; overload protection for the refrigerator; high-pressure pressure switch; overload relay; thermal protection device, and various other safety functions | ||||||
Sealed Recirculation System | The entire system is fully enclosed, producing no oil mist at high temperatures and not absorbing moisture from the air at low temperatures. It won't increase pressure due to high temperatures when not in operation at low temperatures, and automatically replenishes the heat-conducting medium. | ||||||
