Overview

Meling -20°C~-40°C laboratory low temperature freezer DW-FL778 medical freezer is equipped with high-quality refrigeration system for fast cooling. The high-precision temperature control system can display various parameters simultaneously, including power voltage, temperature inside the cabinet and environmental temperature, which can indicate the operation status clearly. And you are free to set the temperature inside the cabinet in the range of -20°C to 40°C. The two-layer heat insulation foamed door with airbag-typed outer steal can prevent loss of refrigerating capacity in an effective way.

High Efficiency Refrigeration System
·Freon-free refrigerant, compressor supplied by an international famous brand and EBM fan can guarantee fast cooling and are energy-saving and environmentally friendly;
·Refrigerating circuit with proprietary intellectual property rights ensures high efficiency and stability;
·Two-layer heat insulating foamed door and the insulation design of the outer door system with multiple patents can prevent loss of refrigerating capacity in an effective way;
·The cabinet are made from high-performance insulation material, improving thermal insulation performance to a large extent.

High-precision Temperature Control System
High-precision microcomputer temperature control system and platinum resistor temperature sensors ensure more precise temperature control.

Human-oriented Design
High-quality steel plate structure with phosphate coating, Galvanized steel sheet (optional stainless steel) liner and low noise design can create a comfortable environment.

Features

The digital temperature display can show various parameters simultaneously, such as temperature inside the cabinet, power voltage and environmental temperature, indicating operating status clearly
The high-precision microcomputer temperature control system and platinum resistor temperature sensors enable users to set temperature inside the cabinet within a range from -20℃ to -40℃
The compressor supplied by an international famous brand and EBM fan is powerful, energy-saving and highly efficient
The large-area finned condenser is characterized by a space equal to or less than 2mm between fins, providing a large area for heat dissipation and satisfactory performance
The two-layer heat insulating foamed door with airbag-typed outer 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 vacuum insulation material, improving thermal insulation performance to a large extent
The well-developed alarm system has multiple alarm functions: high temperature/low temperature alarm, door ajar alarm, power failure alarm, abnormal voltage alarm, sensor failure alarm, low battery alarm, alarm of poor heat dissipation of condenser, system failure alarm, etc.
The turn-on delay and stopping interval protection function can ensure reliability in running
The keyboard lock function and password protection function can prevent any adjustment of operating parameters without permission
The rotating handle facilitates door opening
The adjustable layered structure is convenient for storage of various things
The liner made from Galvanized steel sheet (optional stainless steel 304) for medical use is low- temperature tolerant and corrosion-resistant, which has a long service life and is easy to clean
