Product catalog summary

General Overview
The DW-86L578J is an ultra-low temperature freezer designed for life science applications, offering intelligent protection with a temperature range of -40℃ to -86℃. It features a storage capacity of 578 liters (20.4 cubic feet) and is equipped with advanced refrigeration and control systems.

Environmental & Electrical Data
The freezer operates on a power supply of 220-240V/50Hz, with a power consumption of 9 kW-hr/day and an electrical current requirement of 16A. It has a building supply rating of 50A and a power lead length of 2.5 meters. The ambient temperature range for stable operation is 10℃ to 32℃.

Refrigeration Configuration
The system uses a hermetic reciprocating compressor by SECOP, with a capacity of 950W. It employs a direct cooling method with a cold wall and enhanced heat transfer treatment. The refrigerants used are R290 in the first stage and R170 in the second stage, both flammable.

Controller/Electrical System Features
The freezer is equipped with a microprocessor control system, featuring a bright LED display and USB data export capabilities. It includes adjustable high/low temperature alarms, remote alarm terminals, and a PT100 sensor for setpoint security.

Construction
The exterior is made of color-coated steel plate with a door thickness of 90mm. The interior features four solid doors and three adjustable stainless steel shelves, each with a maximum capacity of 80 kg. The unit is mounted on all-direction casters with a fixing stand.

Performance
The freezer maintains temperature uniformity of +3/-3.4℃ and accuracy of 1℃. It has a cool-down time of 350 minutes from 25℃ ambient to -80℃ and a warm-up time of 40 minutes from -80℃ to -50℃. The noise level is 50 dB(A).

Typical Performance Characteristics
In a 25℃ ambient environment, the freezer supports alarms for high/low temperature, power failure, door ajar, sensor failure, high ambient temperature, hot condenser, and low battery.

Certification
The product is CE certified, ensuring compliance with European safety standards.
