DW-86L579BP SmartFrequency Conversion ULT Freezer

Intelligent Frequency Conversion Technology
Two variable speed compressors are controlled for optimal freezer performance. Low energy consumption is achieved.

Precise Temperature Control
The innovative control algorithm balances the effects of temperature loss with the unique frequency conversion refrigeration system, ensuring the cabinet temperature stability of ±3°C.

World-leading Energy Saving Refrigeration Technology
Our hydrocarbon refrigeration technology can save energy by 50%, significantly reducing operator’s cost. The refrigerants do not contain fluoride and chloride. The global warming potential is extremely low at 3. Thus they are very friendly to the environment.

Maximum Energy Efficiency
Our SmartFrequency Technology, coupled with our environmentally safe and friendly hydrocarbon refrigeration system, allows the Haier freezers to operate at a low level of energy of 8.2 kwh/day.

Frequency Conversion Adaptive Technology
Variable speed compressors in Haier Biomedical freezers are operated to produce the capacity that matches the demand of the load. The control system automatically tunes the speed of the compressors to optimize the operation.

Minimal Sound Level Output
Adaptive control technology controls the fans and compressors to reduce the sound level to 43.5 dba.
