Features:

Safer by Design

DualGuard ULT freezers are engineered to deliver the highest level of protection for high-value, temperature-sensitive samples.
By utilizing two independent refrigeration systems, the DualGuard ensures fail-safe performance. In the rare event that one system fails, the other continues to maintain a consistent -80°C environment safeguarding your critical biological and pharmaceutical materials without interruption.

Globally Trusted Components

Equipped with compressors and fans from internationally renowned brands, ensuring exceptional reliability and up to 20% longer lifespan.

Comprehensive Alarm System

Multifunctional Alarm : High / Low temperature, Sensor error, Power failure, High ambient temp., Door ajar, Door open alarm, low battery alarm.

Superior Temperature Uniformity

Maintains consistent internal temperatures to minimize sample degradation due to fluctuations, safeguarding sample integrity.

Rapid Temperature Pull-Down

Achieves -81°C in approximately 3 hours (at 25°C ambient), minimizing downtime and protecting samples more quickly.

Patented LBA Forming Technology
Innovative cabinet insulation using patented LBA forming agent results in higher density construction, improving space utilization by 10% and enhancing thermal efficiency.

Multi-layer Silicone Sealing Structure
Multi-layers silicone gaskets provide a tight seal between the inner doors and outer door, reducing heat exchange rate and retaining the inner temperature better when there is power failure.

Multi-level Alarms
Alarm functions include high, low temperature, sensor error, power failure, high ambient alarm, door open alarm.

Ingenious Handle Design
Ingenious handle design helps you easy to open and close door easier. Lockable handle safeguards your precious samples. Padlock can also be added for extra sample safety.

Stainless Steel Cabinet
5 inner compartments (4 shelves, 5 inner doors) Abrasive and corrosion resistance, easy clean.

VIP PLUS Vacuum Insulation
VIP PLUS vacuum insulation provides up to 30% more storage capacity than a conventionally insulated freezer.
The advanced VIP Plus vacuum insulation technology offers up to 30% more storage capacity compared to conventional insulation without expanding the freezer's external dimensions. Featuring a high-performance glass fiber core, VIP Plus delivers superior thermal efficiency, ensuring optimal protection of your valuable samples while maximizing internal space.

Heated Pressure Equalization Port 
It allows users to re-open the main door quickly when entering ,rust-proof, freeze-free.

Filter Design
Tool-free removable filter design, easy and quick to clean the filter.

DualGuard Cooling system
DualGuard Cooling System offers the high level security storage. Two independent systems, in the case of an unexpected failure of one cooling circuit, , the other can maintain the freezer’ s temperature uniformly in the -80°C range.

Intelligent Control System
User-Friendly Interface with Advanced Monitoring The DualGuard ULT Freezer is equipped with an integrated microprocessor controller and a clear LED display (optional LCD touchscreen available) to ensure precise control and an optimal user experience.A built-in USB port enables easy data logging and transfer, allowing users to conveniently monitor and manage temperature performance via PC.

Enhanced Heat Exchange for Faster Performance
Our patented D-shaped evaporating tube design increases the heat exchange surface area by up to 15%, significantly improving cooling efficiency. With greater contact between the tubing and internal surfaces, this innovation enables a faster temperature pulldown ensuring quicker stabilization and enhanced sample protection.
1) Enhanced Insulation for Greater Energy Savings
2) Optimized Foaming Layer Design 
A more intelligent foaming structure increases internal storage volume, resulting in higher space utilization without compromising performance

Active ECO Technology
Smart Efficiency Built into Every Unit Active ECO Technology is standard across all Venchal Scientific ULT freezers, enabling them to operate in ECO mode by default.
This advanced system continuously adapts to internal load and temperature changes, automatically adjusting compressor speed for optimal performance.
The result:

  • Significantly reduced energy consumption
  • Consistent interior temperature uniformity
  •  Quiet efficient, and reliable operation
    Experience the perfect balance of energy efficiency and temperature stability with Active ECO Technology.
