Haier Biomedical DW86L578 Ultra-Low Freezers use a unique hydrocarbon refrigeration system to provide maximum efficiency in extreme conditions. The four individual inner doors can be opened independently to minimize frost buildup inside the chamber. Unique door seal design for the minimum loss of cold temperature during a door opening. Stainless steel handle to ensure proper strength for door latching. The specialized control system is designed for a well-balanced operation of the cascade refrigeration system. High-performance VIP insulation panels minimize cabinet heat gain and improve temperature stability.

Safety features include malfunction alarms for high and low temperatures, power failure, sensor error, clean filters, and extremely high ambient temperatures. The alarms are capable of two types of alarm outputs: audible buzzer and flashing light. Multiple built-in system protection features including user-settable protection code for controls, user-settable delay to start, voltage compensation system, and protection against extremely high voltages. Door open feature standard and USB port for temperature data downloading standard on upright models.
