-86°C Ultra Low Temperature Freezer Medical Freezer DW-HL858S

•Fast refrigeration with strong refrigeration system

•Two compressors and EBM fan motor ensure high-efficiency

•Equipped with VIP plus vacuum thermal insulation panel

•D-form copper tube evaporator for heating dissipation

•Reliable audible and visual security system


Meling -40°C~-86°C ultra low temperature freezer DW-HL858 is specially designed as medical freezer and laboratory freezer. The low temperature freezer is equipped with more powerful refrigeration system, ensuring fast refrigeration and temperature uniformity. This upright deep freezer features strong refrigeration, and the power off insulation time is extremely long, providing safe and reliable low temperature protection for samples. You are able to set the temperature inside the cabinet in the range of -10°C~-86°C freely with the high-precision microcomputer control system and platinum resistor sensors. It is equipped with three-dimensional thermal insulation in the deep freezer. And it is adopted high-efficiency VIP plus vacuum insulation plate in the six sides of the cabinet, which improves the thermal insulation performance of the medical / laboratory freezer.  

Powerful Refrigeration System
-40°C~-86°C ultra deep freezer DW-HL858 features fast refrigeration with the help of new generation refrigeration system. And it has the ability to keep temperature uniformity in the range of -10°C~-86°C in the cabinet. This ultra low temperature freezer adopts CFC-FREE mixture refrigerant technology, which can ensure high performance of the temperature and environmentally friendly.

VIP Plus Vacuum Thermal Insulation
The six sides of the cabinet in the upright deep freezer are designed with high-efficiency VIP vacuum thermal insulation plate, which can improve the thermal insulation performance. And it has two-layer insulation foaming door with double seal, which can ensure the temperature uniformity in the cabinet of the ultra deep freezer.

Reliable Security System
This ultra low temperature freezer comes with audible and visible alarm system, including high temperature alarm, low temperature alarm, sensor failure alarm, power failure alarm, door open alarm, low battery level alarm, and system failure alarm. And it features turn-on delay and stopping interval protection to ensure reliable operation.

Human-oriented Structure Design
The door handle is designed in new-type assisting and pressure reducing valve, which can be opened and closed easily with one hand. The liner is designed with 304 stainless steel, which is low-temperature tolerant and corrosion-resistant, ensuring a long service life. And the universal caster and fixed foot under the ultra low temperature freezer are more convenient for movement and fixation.



  Scope of Application

This upright deep freezer is suitable for applying in hospitals, blood bank, health and disease prevention systems, colleges and universities, research institutions, the electronic industry, laboratories in colleges & universities, biological engineering, and more.
