SmartFrequency ULT -86°C Freezer

SmartFrequency Conversion ULT Freezers can be used for products which require strict storage conditions such as viruses, pathogens, red blood cells, white blood cells, skin, bones, bacteria, semen, biological products, ocean products, electronic devices and special materials. Suitable for long term storage, meeting the cold storage requirements found in hospitals, disease control and prevention centres, scientific research institutions biomedical engineering institutes, agriculture/fishery companies as well as the electronics and chemical industry.

  • Two variable speed compressors are controlled for optimal freezer performance. Low energy consumption is achieved.
  • The SmartFrequency technology, coupled with our environmentally safe and friendly hydrocarbon refrigeration system, allows the freezers to operate at a low level of energy of 8.2 kWh/day.
  • 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.
  • Variable speed compressors 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.
  • The 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.
  • Adaptive control technology controls the fans and compressors to reduce the sound level to 43.5 dB(A).
