Overview

 -86℃ Ultra Low Temperature Freezer DW-HL428T built up by two independent refrigeration systems, and the Dual Cooling Systems offers the highest level of protection, only one system work can maintain the freezer around the -80℃. Valuable and irreplaceable samples can always be securely with the highest confidence even if the compressor fails.

 

Two High-efficiency Refrigeration Systems

Two high-efficiency refrigeration sytems work independently, each independent refrigeration system ensures the freezer temperature remains at  -80℃. Valuable and irreplaceable samples can always be securely stored with the highest confidence.

 

Environment Friendly

Employs natural hydrocarbon refrigerants in full compliance with U.S. SNAP and EU (EU_517/2014) environmental regulations. All manufacturing foaming agents are strictly controlled to meet eco-safety standards.

 

User Interface and Functionality

 

-10-inch high-resolution LCD touchscreen with glove-compatible operation

 

-USB port for data transfer, event logs, and system diagnostics

 

-Switchable ℃/℉ display modes for user convenience

 

-Setup wizard and on-screen temperature mapping for simplified configuration

 

-loT Function (WIFI/5V power supply interface/Network interface)

 

-RS485 interface compliance to MODBUS protocol is able to transfer data with
 

 

Energy Efficiency

Equipped with inverter compressors that dynamically adjust operation based on internal conditions. During idle phases, the system runs at minimal speeds to reduce consumption and automatically accelerates following door openings to quickly restore target temperatures.
