TwinGuard ULT Freezers (-86°C) Preservation

Twinguard banner

Our state-of-the-art TwinGuard ULT Freezers utilize two independent refrigeration systems to maintain the ultra-low temperature environment even if one cooling circuit unexpectedly fails. This design offers unparalleled levels of safety and peace of mind.

Following the successful 2010 launch of the world’s first TwinGuard freezer, the PHCbi MDF-U500VX, the higher-capacity MDF-U700VX TwinGuard -86ºC Freezer was introduced in 2011. Since then, customers storing invaluable, irreplaceable, potentially life-saving, or pathogenic samples—such as those at The Pirbright Institute—have benefited from the enhanced assurance, capacity, and advanced features of TwinGuard freezers.

Product Information

Features

Sample Protection

The TwinGuard dual cooling system uses two independent refrigeration circuits to maintain a consistent temperature of -86°C. Even if one circuit fails, the other ensures a stable -70°C environment.

TThis high level of reliability minimizes the risk of sample damage.

Efficient Sample Storage

The newly designed cabinet combines insulated outer doors with inner doors engineered for uniform temperature distribution, improving storage efficiency. Compared to previous models, storage efficiency is increased by approximately 10% without expanding the installation footprint.

Enhanced Access Control

The ergonomic "EZlatch" door handle makes accessing stored samples effortless.

A large, full-color LCD touchscreen offers an intuitive, user-friendly interface for seamless operation.

Improved Energy Efficiency and Reduced Operating Costs

By integrating VIP Plus insulation with the next-generation cabinet design, selecting ECO mode reduces energy consumption by approximately 22% compared to earlier models.

Flexible Storage Options

The interior provides adaptable storage configurations with 3–4 shelves and additional space at the base.

Optional small inner doors (4 or 5) are available to further customize the storage layout.
