-40°C Ultra-low Temperature Freezer DW-FL778C

•High efficiency Refrigeration system

•High-precision Temperature control system

•People-oriented design

Overview

Meling -20°C~-40°C low temperature freezer DW-FL778C 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.

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;

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 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 insulated foamed outer door with seal design prevents loss of cooling capacity effectively;
The well-developed alarm system has multiple alarm functions: high temperature/low temperature alarm, door ajar alarm, power failure alarm, low battery alarm, alarm of poor heat dissipation of condenser, system failure alarm, etc.
The keyboard lock function and password protection function can prevent any adjustment of operating parameters
The liner made from Galvanized steel sheet for medical use is low- temperature tolerant and corrosion-resistant, which has a long service life and is easy to clean.

Scope of Application

Suitable for use in scientific research, cryogenic test on special materials,low temperature resistance test on biological materials, vaccines, biological products and military products, etc. Suitable for use in research institutions, the electronic industry, the chemical industry, hospitals, the health & disease prevention system, laboratories in colleges & universities, military enterprises, etc.
