Biology & Medical New II -86°C Ultra Low Temperature Freezer (DW-HL528S)


New Technology
The new Ultra Low Temperature (ULT) Freezer are special designed for long term storage of
biological samples. Compare to the traditional system, the new designed will present with
lower power consumption, maximize storage capacity, lower noise level, and thus reduce the costing.
Energy efficiency and environmental protection
The famous and reliable imported compressor + Separated evaporator + Compound heat exchanger +
 optimized segregation system + Effective heat insulation system, which reduce the power consumption 40%.
Low noise Operation
With a single compressor operation, the noise level has reduce to approximately 53dBA.
This ensure a quiet and pleasant working environment inside a lab.
Larger Storage Capacity
The special design for biological samples storage can load 30,000 pieces of 1.5ml standard tubes,
and 24,300 pieces of 2ml tubes.(For model DW-HL388S.)

Refrigeration System
■ The advanced refrigeration system of single compressor to provide excellent performance.
■ The 120mm extra-thick insulation with Vacuum Insulated Panels (VIP) effectively reduces the
  leakage of cold air to the Environment.
■ Imported compressor and electromotor fan provide excellent cooling system are reducing the
  noise level and power consumption.
■ Interior temperature ranging from -40°C ~ -86°C can be set freely, controlling precision is 1°C.
