Haier Dual System Ultra Low Temperature Refrigerator DW-86L578S

Haier Dual System Ultra Low Temperature Refrigerator DW-86L578S

●New appearance: The brand new exterior design gives a refreshing feeling and highlights the theme of the product's reverence for life;

●Safety: With a dual system design, in the event of a single system failure, the temperature inside the box can be maintained at -80 ℃ to ensure sample safety;
Ultra energy-efficient: a more hydrocarbon refrigeration system with a daily output of 11.0 kWh, consuming the same amount of electricity as similar products worldwide; On average, each unit saves nearly 3500 yuan in electricity costs per year (3 units save 10000 yuan per year)

●Super insulation: Double foam inner and outer doors combined with five layer sealing design, optimized ultra thick VIP insulation technology, with a 2-hour delay in power outage and temperature return, and a 20% increase in insulation efficiency;

●High uniformity: The refrigeration system control, combined with a special evaporation pipeline route, achieves a uniformity of ± 5 ℃ within the entire chassis;
Super intelligent: The whole machine adopts a 10 inch capacitive touch screen, which is easy to operate; Equipped with IoT functions, mobile terminals, and cloud services for sample storage, it is more intelligent;

●Super Memory: Comes with USB as standard, allowing for free download and export of temperature monitoring data and event records throughout the 10-year lifespan

●Multiple safety locks: integrated handle, standard key lock, can hang padlock, optional electromagnetic lock and fingerprint lock; Multiple insurance, locking sample safety.

●Adjustable ambient temperature: The ambient temperature alarm temperature is adjustable between 30~50 ℃ to prevent frequent machine alarms in environments above 30 ℃.

Haier Dual System Ultra Low Temperature Refrigerator DW-86L578S●Haier's dual system ultra-low temperature adopts dual independent system self stacking hydrocarbon refrigeration technology. The two systems operate independently and alternately, and each refrigeration system can meet the user's required -80 ℃ storage environment. When one system fails, the other system can still ensure that the temperature inside the box is within the range of -80 ℃± 5 ℃.

●The dual system ultra-low temperature storage box is composed of two identical independent refrigeration systems. Each system can serve as a separate refrigeration unit to provide a frozen storage environment inside the box. The refrigeration method of each system is a single machine self cascade refrigeration system, which uses a compressor to compress refrigerants with different evaporation temperatures. The medium temperature refrigerant and low-temperature refrigerant are separated by a gas-liquid separator, and the medium temperature refrigerant cools and condenses the low-temperature refrigerant in the intercooler, making the low-temperature refrigerant reach a liquid state. After throttling, the refrigeration effect is achieved;

●We use hydrocarbon refrigerants, which are more energy-efficient and environmentally friendly.

●Haier's dual system ultra-low temperature has passed the quality certification center testing, and the DW-86L578S has an energy consumption of 11.0kWh/24h. Simultaneously obtaining energy-saving and environmental certification for the ultra-low temperature brand issued by the Quality Certification Center

●Haier's dual system ultra-low temperature adopts carbon hydrogen self cascade refrigeration, with a large unit cooling capacity and fast cooling speed (180min), which can meet the user's demand for rapid cooling after sample access; After 1 minute of normal opening and closing of the door, the temperature inside the box can quickly recover to below -75 ℃ as required by the user, ensuring sample safety.

●The Haier dual system ultra-low temperature box insulation adopts Haier cabinet port design technology and VIP vacuum insulation material. The door seal adopts a five channel silicone sealing structure, effectively improving the overall insulation performance, which can help users fight for sample transfer time and backup power supply preparation time in case of power failure.
