Haier, Ultra Low Temperature Freezer, Model DW-86L578J, Energy Saving 578L

 
***This freezer was tested to specifications. We ran this unit overnight at our facility and was able to reach  -86C. Unit is preowned with minimal wear from normal use, (scratches on front control panel.)  30-day warranty included with purchase. See photos for details. 

Haier Energy Efficient 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. Specialized control system is designed for a well-balance operation of 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 temperature, power failure, sensor error, clean-filter, and extremely high ambient temperature. 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 extreme high voltages. Door open feature standard and USB port for temperature data downloading standard on upright models.
