Project Brief

Traditional low-temperature freezers often face issues such as unstable temperature control, inefficient cooling, and high energy consumption, increasing the risk of sample failure and imposing additional management and maintenance burdens on users.

Addressing these challenges, the DW-86L585MG adopts a precise temperature control system and efficient refrigeration technology. It seamlessly integrates intelligent operations, personalized storage, and eco-friendly concepts, providing users with an efficient, energy-saving, safe, and convenient ultra-low temperature storage solution.

Project Innovation/Need

Featuring an efficient two-stage cascade refrigeration system, the freezer enables rapid cooling while maintaining stable operation even at -86°C, showcasing its energy-efficient, eco-friendly, and reliable storage performance. The freezer boasts a large capacity to accommodate up to 40,000 2ml cryovial samples. Its interior design includes drawer-type and adjustable shelf-type partitions, facilitating scientific classification and flexible adjustment of storage space according to practical needs.

Based on RFID technology, this freezer integrates advanced features such as intelligent item recognition and comparison, automatic data logging, and light-sensing positioning assistance. Dual ambient LED strips fitted at the top and bottom visually communicate the device's operational or capacity status through distinct colour changes and lighting effects, simplifying the management process and enhancing transparency.

Additionally, the freezer incorporates a diversified identity verification mechanism, including Face Recognition, Fingerprint Recognition, NFC Recognition, and Password Verification. It also features remote alarm functionality, which sends immediate alerts via SMS and APP when any device anomaly is detected, enhancing security and monitoring efficiency during storage.

Design Challenge

The design challenge lies in the enhancement of the intelligent features of the freezer. To simplify operational procedures and improve user experience, the freezer tightly associates sample base information with storage locations, enabling quick location based on this information. It records critical details such as the time of sample insertion and removal, as well as the operator, establishing a comprehensive log of sample handling for easy traceability.

Equipped with a high-precision temperature control system, it achieves accurate temperature regulation within the freezer through microcomputer control technology, ensuring the stability of the sample storage environment. A clear temperature display screen allows users to monitor internal temperatures in real-time. Furthermore, it supports wireless/wired transmission of temperature data to remote monitoring systems, providing detailed tracking for each operation.

Sustainability

The freezer's exterior is made from galvanized steel plates and treated with meticulous painting processes, enhancing corrosion resistance to withstand rigorous medical environments while presenting an aesthetically pleasing appearance.

The robust and durable nature of the exterior provides reliable protection against external collisions and damage. The inner chamber is constructed from high-quality brushed 304 stainless steel, ensuring long-lasting durability due to its excellent corrosion resistance. Moreover, the selection of environmentally friendly hydrocarbon refrigerants realizes efficient and low-consumption operation, contributing positively to environmental protection.
