Product catalog summary

General Overview: The document provides technical specifications and performance details for the DW-86W420J Ultra-Low Temperature (ULT) Freezer, designed for life science applications. It highlights the freezer's intelligent protection features and its capability to maintain extremely low temperatures.

Environmental & Electrical Data: The freezer operates on a power supply of 220-240V/50Hz or 208-230V/60Hz, with a power consumption of 7.5 kW-hr/day. It has a building supply rating of 16A and a noise level of 49 dB(A). The ambient temperature range for operation is 10℃ to 32℃.

Refrigeration Configuration: The system uses a hermetic reciprocating compressor by SECOP, with a direct cooling refrigeration system. It employs R290 refrigerant in the first stage and a mix of R290+R170 in the second stage, both of which are flammable. The defrost method is manual.

Controller/Electrical System Features: The freezer includes a microprocessor control with a bright LED display and USB data export capability. It features adjustable high/low temperature alarms, auto voltage safeguard, and remote alarm terminals.

Construction: The exterior is made of color-coated steel plate, while the interior is stainless steel. The freezer has a door thickness of 80mm and cabinet thickness of 140mm, with three solid inner doors.

Performance: The freezer supports alarms for high/low temperature, power failure, door open, sensor failure, high ambient temperature, hot condenser, and low battery. It has a temperature uniformity of ±6℃ and accuracy of ±1℃. The cool down time from 25℃ ambient to -80℃ is 150 minutes, and warm-up time from -80℃ to -50℃ is 30 minutes.

Certification: The product is certified with CE and UL standards.

Dimensions: The total dimensions are 2130mm x 870mm x 1020mm, with an inner cabinet size of 1367mm x 462mm x 652mm.
