This ultra low temperature freezer includes a premium compressor, which is compatible with high-efficiency mixture gas refrigerant and helps reduce energy consumption and improve refrigeration performance. The interior temperatures are controlled by a dual-core microprocessor, and it’s clearly displayed on a high-definition digital screen, allows you to monitor and set the temperature to fit the proper storage condition. This ultra-low freezer has an audible and visible alarm system to warn you when storage condition is out of abnormal temperature, the sensor fails to work, and other errors and exceptions may occur, greatly protect your stored materials from spoilage. Unique two times foaming technology, super thick insulation which greatly improves the insulation effect;vacuum insulation board, tightly locks the cold air to ensure the great insulation effect.

Details

NW-DWZW128-4

The external of this laboratory fridge freezer is made of premium steel plate finished with powder coating, the interior is made of 304 stainless steel, the surface features anti-corrosion and easy cleaning for low maintenance. The top lid has a horizontal type handle and assisting balanced hinges for easy opening and closing. The handle comes with a lock for preventing unwanted access. Swivel casters and adjustable feet at the bottom for more easy movement and fastening.

NW-DWZW128-3

This medical cryogenic freezer has an outstanding refrigeration system, which has features of rapid refrigeration and energy saving, the temperatures are kept constant within a tolerance of 0.1℃. Its direct-cooling system has a manual-defrost feature. The mixture gas refrigerant is environmentally friendly to help improve working efficiency and reduce energy consumption.

High-Precision Temperature Control | NW-DWZW128 cryogenic freezer

The interior temperature of this cryogenic freezer is controlled by a high-precision and user-friendly dual-core microprocessor, it’s an automatic type of temperature control module, the extra-low temperature ranges from -120℃ to -164℃. A high-precision digital temperature screen has a user-friendly interface, it works with built-in high-sensitive platinum resistor temperature sensors to display the interior temperature with a precision of 0.1℃. A printer is available to record the temperature data every twenty minutes. Other optional items: chart recorder, alarm lamp, voltage compensation, remote communication centralized monitoring system.

Security & Alarm System | NW-DWZW128 cryogenic chest freezer

This cryogenic chest freezer has an audible and visual alarm device, it works with a built-in sensor to detect the interior temperature. This system will alarm when the temperature goes high or low abnormally, the top lid has left open, the sensor doesn’t work, and the power is off, or other problems would occur. This system also comes with a device to delay turn-on and prevent interval, which can ensure working reliability. The lid has a lock for preventing unwanted access.

Thermal Insulation System | NW-DWZW128 laboratory fridge freezer

The top lid of this laboratory fridge freezer includes 2 times of polyurethane foam, and there are gaskets on the edge of the lid. The VIP layer is super thick but greatly effective on insulation. The VIP vacuum insulation board can tightly keep the cold air locked inside. All these great features help this freezer improve the performance of thermal insulation.
