-86°C hydrocarbon ULT freezer
- Temperature Control System : Controlled by a micro-computer, LCD display, touch screen eye level control panel; The inner temperature can be adjusted at the range of -40°C~-86°C, and the temperature regulation accuracy is 0.1°C. ambient temp +15 to +32°C.
- Security Control System : Multi malfunction alarms: high-temperature alarm, low-temperature alarm, sensor malfunction alarm, condenser dirty alarm, low battery alarm, power failure alar, overpressure alarms, over ambient temperature alarms, open the door alarms and so on for safe use; Besides, you can check history alarming information and derive data. All the history data can be saved over 10 years; Three alarming methods: buzzer alarming, independent icon alarming, and remote alarming; Protection function: compressor power-on
delay protection, time between power off; overpressure protection, password protection and normal operation protection under failure mode, door lock. Password protection can prevent parameters from being changed randomly. Display screen with running indication and communication status indication can show real-time operation of the freezer; The power switch has two-way fuse over-current protection, together with the power-on indicator light ensure safety.
Refrigeration System : Optimized cascade refrigeration technology, special evaporation system and condensation system, strong refrigerating efficiency, CFC HCFC free natural Refrigeration International famous brand compressor and EBM fan electromotor and oil separator, stable product performance, strong refrigerating efficiency; Enhanced sealing design: double door seal.
Humanized Design : Unique handle design: the door can be opened by both hands, individual press lock on the handle and 2 padlocks; Wide voltage design can help it work stably under 198-254V; Can show the temperature curve and history data, and have derive data function; Press-out type dust removal screen with locks, simple and convenient for maintenance; Thermometer holes design for temperature examination, Battery backup for control system up to 24 hours at to power failure.
Individual Removable Foam Inner Doors
