Meling -40°C~-86°C ultra low temperature freezer DW-HL778s is a laboratory deep freezer as well as medical freezer. The ultra deep freezer is equipped with new generation refrigeration system, ensuring fast refrigeration. The high-precision microcomputer control system and platinum resistor sensors enable you to set the temperature inside the cabinet in the range of -10°C~-86°C freely. This deep freezer enables three-dimensional thermal insulation. And the six sides of the cabinet are made from high-efficiency VIP Plus vacuum insulation panel, which can improve the thermal insulation performance of the refrigerator. This upright deep freezer is suitable for applying in hospitals, blood bank, health and disease prevention systems, colleges and universities, research institutions, biological engineering, and more.

Powerful Refrigeration System

-40°C~-86°C ultra low temperature freezer DW-HL678s provides you with new generation refrigeration system ensuring fast refrigeration. And it can well keep the temperature in the cabinet in the range of -10°C~-86°C. The CFC-FREE mixture refrigerant ensures well performance of the temperature and environmental friendly.

VIP Plus Vacuum Thermal Insulation

The deep freezer is designed with high-efficiency VIP vacuum thermal insulation plate in the six sides of the cabinet. The two-layer insulation foaming door with double seal can greatly improve the thermal insulation performance and ensure temperature uniformity in the cabinet of the ultra low temperature freezer.

Reliable Security System

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

Human-oriented Structure Design

The new-type assisting door handle is designed with pressure reducing valve, which can be opened and closed easily. The 304 stainless steel liner is low-temperature tolerant and corrosion-resistant, which can ensure a long service life. And it has universal caster and fixed foot for easily moving and fixing.
