Product catalog summary

Overview: The document provides detailed specifications and features of the Water-Cooled Ultra-Low Temperature (ULT) Freezers, models DW-86L828W and DW-86L959W, designed by Biomedical Co., Ltd. These freezers are engineered for energy efficiency and reduced heat emissions, making them suitable for high ambient environments with limited air conditioning options.

Specifications: The freezers maintain a temperature uniformity of ±3°C at a setting of -80°C. They feature a microcomputer control system with a 10-inch LCD capacitive screen for precise temperature display and control, adjustable between -40°C and -86°C. The freezers are equipped with a water-cooled system that significantly reduces energy consumption and heat emissions by 90%.

Control and Safety Features: The intelligent control system includes multiple alarm functions for high/low temperature, hot condenser, power failure, low battery, high ambient temperature, and door ajar. The system supports USB and remote alarm connectivity, ensuring comprehensive monitoring and safety. The freezers also feature a stand-alone sample management system and superior thermal insulation with a 90mm VIP and polyurethane foam door.

Design and Construction: The freezers are designed with multiple safety locks, including options for electromagnetic locks and fingerprint recognition. The door features four layers of external seals and a single inner door seal to minimize cold air loss. The product includes a pocket organizer, document storage, and an easy-to-remove and clean filter.

Networking and Data Management: The freezers come with an R485 interface for multi-refrigerator networking and a USB port for downloading and exporting up to 10 years of temperature monitoring data. In case of power failure, two lithium batteries can maintain the LCD screen for up to 22 hours.

Dimensions and Models: The document provides detailed dimensions for both models, including overall width, depth, and height, as well as inner liner and shelf dimensions. The DW-86L828W and DW-86L959W models differ slightly in size but share similar technical specifications and features.

Technical Performance: The freezers operate with a microprocessor controller and use HC refrigerant. They are designed to meet CE standards and offer optional features such as a CO2 backup system and temperature recorder.
