PRODUCT INFO

Haier -86°C ULT Freezer - Model DW-86L959BP is a market leader in the -80 freezer category. Regarded as one of the most energy-efficient ultra-low -80 freezers in the market, this unit has become a best seller in Asia, Europe, and Australia.

KEY FEATURES

FREQUENCY CONVERSION TECHNOLOGY
Two frequency conversion compressors, designed with adaptive control, follow user patterns and adjust the refrigeration system, substantially reducing energy without compromising performance. Unlike standard, single-speed compressors that cycle on and off, our frequency conversion compressor runs at variable speeds to adjust cooling performance to the conditions inside and outside of the freezer. It allows the freezer to adjust to factors such as start-up and door openings when a higher compressor speed is needed. When conditions are normal or stable, the drive runs at a lower speed while still protecting the samples.

MAXIMUM ENERGY EFFICIENCY
Due to our SmartFrequency refrigeration technology, innovative cabinet design, and the use of hydrocarbon refrigerants, this range of freezers has the lowest energy consumption figures to date at just 8.2kWh/day.

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.

ENERGY SAVING TECHNOLOGY
The hydrocarbon refrigeration technology saves energy by 50%, significantly reducing the running costs of the freezer. Hydrocarbon refrigerant contains no fluorine or chlorine and has a global warming potential (GWP) value of just 3, meaning this refrigerant is a more environmentally friendly option compared to HFC refrigerants.

MINIMAL NOISE OUTPUT
Adaptive control technology controls fans and compressors to reduce noise levels to an exceptional 43.5dB.
