Meling -20°C~-40°C low temperature freezer DW-FL531 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 -10°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;
·Six sides of the cabinet are made from high-performance vacuum 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, stainless steel liner and low noise design can create a comfortable environment.
