Biomedical C (Double Doors Type) C (Double Doors Type) The C deep freezer offers a large capacity storage space with fast temperature performance. Integrated design of cold shelf and evaporator provides additional refrigeration efficiency. This product is designed to store vaccines, blood plasma, and many other biological materials. Installations can be found in research institutions and clinical sites in life science, electronic testing and medical markets. Haier s next generation low temperature storage freezer, DWL348, is designed based on the original work horse platform of DWL508. The new freezer model operates with two capillary tubes and is equipped with dual gaskets to improve the temperature uniformity through the chamber drastically. It can be installed to satisfy tougher application requirements in universities, research institutions and blood banks. Reliability and Key Features Rated for C at 32 C ambient Rapid cooling with shelf evaporator Improved temperature uniformity with dual capillary tube design at the range of -20 C to C Improved door seal design with two gaskets maintains cabinet temperature more efficiently Frost buildup is reduced Insulation thickness is 90 mm for additional robustness, less power consumption and more temperature retaining ability Drawer design maximizes storage space. One unit can hold 360 bags of 230 ml blood bags Multiple malfunction alarms include highlow temperature, power failure, sensor error, low battery, highlow ambient temperature Two types of alarms: buzzer and flashing light DWL508 DWL348 Control panel Drawer Shelf Handle digital display for clear observation Double door design with independent locks reduces air leakage to ensure temperature stability and lower power consumption Tracks to label drawers for product identification 41 42
