Ultra Low Temperature Freezer DW-86W420, ULT Freezer

Ultra Low Temperature Freezers DW-86W420， ULT Freezer

The first ultra low temperature freezer with mobile messagealarm and remote monitoring function in the world.

Haier ULTfreezers are suitable for use in blood banks, hospitals, epidemic preventionservices, research institutes, electronics and chemical plants laboratories,biological engineering institutes, and transoceanic fishery companies.

1.       TemperatureControl

1)       Microprocessorcontrolled, digital display with a 1℃temperature increment and an adjustable cabinet temperaturerange of -40℃~-86℃.

2.       Safety Control System

1)       Malfunction alarms include conditions such as thetemperature exceeding the set range, power failure, sensor error, voltage rangeexceeded, condenser under efficiency, and ambient temperature exceeding theacceptable range.

2)       Audible andvisible alarm indications via sounding buzzer and flashing light.

3)       Multiple levelprotection functions include password input, start-up delay protection, andvoltage protection in the event of low or high voltage.

4)       All individualparts in the ultra low temperature freezer are grounded safely.

5)       Every HAIER freezer has a controller on the front of the cabinet doorwith built-in software which displays the necessary components (such ascompressors, voltage sensors, and cabinet and ambient temperature sensors) toaid in quickly identifying the cause of  a fault or set a temperaturevariance. We call this SYSTEMS MONITORING AND REPORTING TECHNOLOGY and itenables display of the part that is having a problem on the controller itself.This type of inbuilt fault identification can help the customer identify andreport to our service staff which part is in need of repair should it becomenecessary for our service engineers to come onsite.

3.       Refrigeration System

1)       Optimized cascade refrigeration technology.

2)       High efficiency Danfoss compressor.

3)       The ultra low temperature freezer DW-86W420 hasextra thick, high-density insulation material formaximum temperature preservation.

4)       Specially designed triple-layer sealing structure and heat-insulationsystem to reduce frost formation.

5)       Speciallydesigned computer control system for low temperature stage to prevent overloading of the second stage compressor.

4.       Ergonomic Design

1)       LED display foreasy observation of cabinet temperature, set temperature, ambient temperature,input voltage, temperature alarm settings and early warnings for malfunctions.

2)       The ULT freezerhas an adjustable multi-level shelf system for easy operation.

3)       Safety lock toprevent unauthorized access.

4)       Broad 10℃~32℃ ambient working temperature range.

5)       Innovativeintegrated door handle and lock, compact casters, and flexible and easyoperation.

6)       Pressure-equalizingport for ease of re-entry after closing the door.

7)       The ultra lowtemperature freezer comes with an intelligently controlled condenser fan forhigher energy savings.

8)       Advanced remotemonitoring and voltage compensation system.

9)       Optional storagebox.

5.       VIP TemperaturePreservation Technology

1)       Reduced heattransmission from ambient temperature.

2)       Improvedinsulation performance with thinner walls.

3)       Small unit footprint area.

4)       Increased ULT freezer interior volume.

5)       Use of flame retardant VIP materials.

6)       Use of pollution-free, nano-materials and CFCfree.
