Product catalog summary

General Specifications:
The DW-86L388J is a C ULT Freezer designed for life science applications, offering a storage capacity of 388 liters (13.7 cubic feet) and operating within a temperature range of -40℃ to -86℃. It has a net weight of 255 kg and a gross weight of 286 kg. The freezer dimensions are 830mm x 980mm x 1980mm.

Environmental & Electrical Data:
The freezer operates on an electrical power supply of 220-240V/50Hz, with a power consumption of 8 kW-hr/day and an electrical current of 8A. The building supply rating required is 16A. The power lead length is 2.5 meters, and it has a heat rejection of 27297 BTU/day in stable operation, suitable for ambient temperatures between 10℃ and 32℃.

Refrigeration Configuration:
The refrigeration 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 defrost method is manual, and the refrigerants used are R290 in the first stage and R170 in the second stage, both flammable.

Controller/Electrical System Features:
The freezer features a microprocessor control with a bright LED display and USB data export capability. It includes adjustable high/low temperature alarms, a remote alarm port, and optional RS232/RS485 connectivity. The controller sensor is a PT100, and the power switch is an on-off type with a circuit breaker.

Construction:
The freezer is constructed with a color-coated electric zinc steel plate exterior and a cold plate steel interior. It has a double solid door with a 130mm cabinet thickness and a 90mm door thickness. The insulation is provided by VIP+LBA foaming agent, and the door seals include one seal on the interior door strip and four seals on the exterior door strip. It includes three stainless steel adjustable shelves, each with a maximum capacity of 50 kg.

Performance:
The freezer supports alarms for high/low temperature, power failure, door ajar, sensor failure, high ambient temperature, hot condenser, and low battery. It has a temperature uniformity of +2.8/-2℃ and a temperature accuracy of 1℃. The cool-down time from 25℃ ambient to -80℃ is 360 minutes, and the warm-up time from -80℃ to -50℃ is 45 minutes.

Typical Performance Characteristics:
The freezer maintains an average temperature of -79.2℃ across various points, with maximum and minimum temperatures ranging slightly around this average. The performance is based on internal testing under a 25℃ ambient temperature.

Certification:
The product is CE certified.
