Meling is the market leader for Ultra Low temperature manufacturers -20°C ~-40℃ Ultra-low temperature freezer DW-FL450 is special for medical freezer and lab freezer. This Ultra-low temperature freezer is designed with two compressors and two chambers, which allows you to control the upper chamber and lower chamber independently. And the high-precision microcomputer temperature control system has the ability to set the temperature inside the cabinet in the range of -20°C ~-40°C. The built-in door gasket can perfect maintain a constant inside temperature and is easy to clean. The Ultra-low temp freezer is best for storage of various medical and scientific materials, including reagent, and more.
Environmentally Friendly Refrigeration System
The environmentally friendly Freon-free refrigerant and high-efficiency enclosed compressor supplied by a famous brand can ensure energy saving and low noise. The condenser installed on the bottom ensures temperature stability and system reliability.
High-precision Temperature Control
The high-precision computerized temperature control system ensures an adjustable temperature within a range from -20 to -40℃ inside the cabinet. The freezer is equipped with two compressors, so independent control of the upper chamber and lower chamber can be realized.
Audible & visual Security System
The well-developed audible & visual alarm system (sensor failure alarm, door ajar alarm, high temperature/low temperature alarm, comunication failure etc.) makes it safer for storage; The turn-on delay and stopping interval protection function can ensure reliability in running.
Human-oriented Structure Design
The arc angle-shaped door frame and cabinet design makes its appearance more attractive. The built-in door gasket is dustproof and easy to clean. Each of the refrigerating chamber and the freezing chamber is equipped with 6 drawers, which are convenient for storage of things.
