DW-HL-528 Ultra Deep Freezer; It is produced for the long-term storage,
preservation and preservation of various biological products, including
viruses, microbes, erythrocytes, leukocytes and cutis. It provides minimum
energy consumption and maximum cooling with its High efficiency
Cooling Components. All components in the system are designed to work
in perfect silence.

KEY FEATURES

Low Noise Design Low-noise direct cooling circuit + suspension frame & sound absorbing compartment & low-noise fan can reduce noise generated by the entire freezer to the largest extent.
Five Magic Weapons for Energy Saving Imported high-efficiency compressor + separated evaporator + composite heat exchanger + optimized fractional condensation & separation system + high-efficiency thermal insulation system can save energy and reduce power consumption of the freezer by 40%.
Three-dimensional Thermal Insulation The six sides of the cabinet are made from high-efficiency VIP vacuum thermal insulation plate, and the thermal insulation design of the inner door made from foaming material and the outer door system was awarded with multiple patents, which can improve the thermal insulation performance of the freezer.
Targeted Refrigeration The new generation of ultra-low temperature refrigeration system can ensure fast refrigeration and was awarded with the Second Prize under State Technological Invention Award.
Optional Accessories(WiFi/Bluetooth printer/Magnetic lock/Swipe card/ Fingerprint) Connect WiFi to upload data to the cloud space, monitor the device, check the status of the freezer faster, and ensure the safety of the samples; Optional Bluetooth printer, real-time export temperature data, temperature graph, setting operation and other data, to understand the freezer operating status; Optional functions such as card unlocking, fingerprint unlocking, and facial recognition unlocking are available to facilitate quick access to samples.

7" HD Intelligent Screen Control System
·7-inch HD intelligent display touch screen, userfriendly interface and more accurate temperature control, with Bluetooth, WiFi and other functions, more convenient operation and more comprehensive functions
·Can add multiple user accounts to log in and record usage/operation records.
·The high-precision microcomputer control system and platinum resistor sensors enable users to set temperature inside the cabinet within a range from -40 to -86°C;
·Optional functions such as card unlocking, fingerprint unlocking, and facial recognition unlocking are available to facilitate quick access to samples.

Data Storage
The temperature data recorded by the system can be exported, the operating data of the system
settings, the alarm data, and the temperature data can be recorded in 5 minutes, and the data can be
recorded for up to 10 years, which can effectively record the running status of the product for you for
a long time.

Thermal Insulation System
·The two-layer heat insulating foamed door with inner and outer door seal and the insulation design
of the outer door system with multiple patents can prevent loss of refrigerating capacity in an effective way.
·The six sides of the cabinet are made from high-performance VIP vacuum insulation material, improving thermal insulation performance to a large extent.

Security System
·The perfect audible & visual alarm system : high and low temperature ,sensor failure ,power failure ,low battery ,door ajar ,main board communication error etc.
·Equipped with alarm self-recovery function, it reminds users of unhandled alarm problems in freezer many times.
·The compressor start delay and stopping interval protection can ensure reliable operation.
·Both the touch screen controller and key-board controller have password protection which can prevent any adjustment of operation without permission.

Refrigeration System
·The imported high-efficiency compressor and EBM fan are energy-saving and highly efficient;
·The large finned condenser with a space between fins 2mm, providing effective heat dissipation.

Supplies for Cryopreservation
Freezer racks/boxes for cryopreservation are optional.

Remote alarm contact, RS485
Equipped with RS485 and remote alarm interface to realize remote observation of freezer operation status, real-time reception of product operation information, and ensure the storage safety of samples.

Human-oriented
·The new designed assisting handle and vacuum release port let the freezer be operated singlehanded
to open and close the outer door.
·The newly added file box makes recording easier and more convenient.
·The liner made from Galvanized steel sheet/ Stainless steel for medical use is lowtemperature tolerant and corrosion-resistant, which has a long service life and is easy to clean;
·The universal casters and leveling feet design are more convenient for movement and fixation.

Area of application
Suitable for use in blood banks, hospitals, health and diseasep revention systems, research institutions,
colleges & universities, the electronic industry, biological engineering, laboratories in colleges &
universities, military enterprises, deep-sea fishing companies, etc.
