This series of laboratory refrigerators and freezers offer 6 models for different storage capacities that include 398/528/678/778/858/1008 liters, operates with temperatures from -40℃ to -86℃, it’s an upright medical freezer that is suitable for freestanding placement. This ultra low temperature freezer includes a premium compressor, which is compatible with environmental-friendly CFC-free mixture refrigerant, helps reduce energy consumption, and improves refrigeration performance. The interior temperatures are controlled by an intelligent microprocessor, and it’s clearly displayed on a high-definition digital screen with an accuracy of 0.1℃, allows you to monitor and set the temperature to fit the proper storage condition. This ultra-low medical deep 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. The front door is made of stainless steel plate with a polyurethane foam layer that features perfect thermal insulation. With these beneficial features above, this freezer provides a great refrigeration solution for hospitals, pharmaceutical manufacturers, research laboratories to store their medicines, vaccines, specimens, and other temperature-sensitive materials.
The door handle is designed as a rotation lock and a valve, that can release the internal vacuum to open the outer door more easily. The liner of the freezer is made of a premium galvanized steel plate, which is low-temperature tolerant for medical application, and it’s easy to clean and has a long lifespan. Swivel casters and adjustable feet at the bottom for more easy movement and fastening.
The laboratory refrigerators and freezers have a high-quality compressor and EBM fan, which are high-efficiency and low-energy. The finned condenser has a large size and is designed with a space between fins≤2mm, operating efficiently at heat dissipation. For models (NW-DWHL678S/778S/858S/1008S), they are equipped with double compressors, if one doesn’t work, another one would keep going with the stable temperature at -70℃. This freezer includes a VIP board to perform high-efficiency refrigeration. The interior of the door is surrounded by a hot gas pipe for defrosting.
The storage temperature of this medical chest freezer is controlled by a high-precision and user-friendly digital microprocessor, it’s an automatic type of temperature control module, which comes with platinum resistor sensors, the adjustable temperature range is between -40℃~-86℃. The 7’ LED touch screen digital screen features a high-definition display and user-friendly interface, it works with built-in and high-sensitive temperature sensors to display the interior temperature with a precision of 0.1℃. A built-in USB interface for data storage.
The exterior door of this medical deep freezer includes 2 layers of polyurethane foam, and there are gaskets on the edge of both the exterior door and interior door. The 6 sides of the cabinet made of high-performance VIP vacuum insulation material. All these features greatly help this freezer improve the performance of thermal insulation.
This freezer has an audible and visual alarm device, it works with some temperature sensors to detect the interior temperature. This system will alarm when the temperature goes high or low abnormally, door 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. Both touch screen and keypad are protected by password access, for preventing operation without permission.
