-86°C Ultra-Low Temperature (ULT) Freezer Series

-86°C Ultra-Low Temperature (ULT) Freezer Series

Product Overview

The -86°C Ultra-Low Temperature Freezer series is designed to provide a secure and stable environment for the long-term preservation of high-value biological samples. These units are essential for scientific research institutes, disease control centers, hospitals, blood stations, and industries involving bioengineering and electronics. Whether you need a compact personal under-counter model or a large-capacity vertical unit with an intelligent dual system, our series ensures maximum sample safety and energy efficiency.

Core Advantages

• Dual Cooling Systems: Select models feature two independent refrigeration systems; if one system fails, the other can maintain the internal temperature at -80°C, providing a dual safety guarantee.

• Energy Efficiency: Utilizes hydrocarbon (HC) refrigerants and variable frequency compressors, reducing energy consumption by up to 30%.

• Intelligent Control: Features include 10.1-inch Android touch screens, real-time temperature monitoring, and high/low temperature alarms.

• Superior Insulation: Equipped with 130mm thick insulation layers and double-seal structures to minimize temperature fluctuations.

• Advanced Safety: Comprehensive alarm system for power failure, sensor fault, condenser dirty, and low battery level.

• User-Friendly Design: Innovative handle design for easy opening, built-in pressure balancing valves, and a muting design to keep noise levels below 55dB.

  FAQ

  1. What makes the "Dual System" safer for my samples? The Dual System consists of two independent refrigeration circuits. If one system encounters a failure, the other can independently maintain the cabinet at -80°C, preventing sample damage.

  2. How much energy can these ULT freezers save? By using hydrocarbon (HC) refrigerants and optimized auto-cascade technology, these freezers can reduce energy consumption by approximately 30% compared to traditional models.

  3. Is there a compact model available for small labs? Yes, the DW-86L66 and DW-86L106 are personal ULT freezers designed to fit under desks or in tight spaces.

  4. What kind of data tracking does the freezer provide? Operating temperature data can be stored for over 10 years, and models with Android screens support event logs and temperature curve displays.

  5. What is the benefit of using hydrocarbon refrigerants? HC refrigerants are environmentally friendly and highly efficient, leading to faster pull-down times and lower global warming potential (GWP).

  6. How is the security of the settings managed? The freezers feature password protection to prevent unauthorized adjustment of parameters and a lockable handle for physical security.

  7. Does the door design help with temperature stability? Yes, the units use a super-dual seal design and 130mm thick insulation to ensure internal temperature uniformity and minimal cold loss.

  8. Why is there a pressure balancing valve? The heated free-pressure balancing valve allows users to reopen the door easily shortly after closing it by equalizing internal and external pressure.

  9. Can I monitor the freezer status remotely? Advanced models support IoT and WEB-based management systems, allowing users to inspect freezer status from various platforms at any time.

  10. What is the noise level of these freezers? The muting design, including optimized compressor room layouts and variable frequency compressors, keeps noise levels below 55dB.

  11. What alarms are built into the system? Standard alarms include high/low temperature, power failure, sensor fault, low battery level, and open door alerts.

  12. How many samples can the larger models hold? For example, the DW-86L707T can store approximately 50,000 samples of 2ml cryopreservation tubes.
