Cryometrix B-90 Blast/Thaw Freezer
Blast freeze your products faster than you ever imagined possible. The Cryometrix B-90 Blast/Thaw Freezer uses patented liquid nitrogen (LN2) technology to reach ultra-low temperatures in a fraction of the time it would take a typical mechanical freezer.
This is far from your ordinary ultra low freezer. The B-90 sets a new standard for efficiency and reliability in blood banking, pharmaceutical, biotechnological, and research environments. Read on to discover how it achieves extreme temperature pull-downs, why it drastically reduces maintenance, and how its built-in thawing feature can simplify your processes.
Ultra-Fast Blast Freezing
Imagine dropping your freezer bay from +20°C to -90°C in about ten minutes — no waiting around for hours like you do with a mechanical system. With the Cryometrix B-90, that’s exactly what you’ll experience thanks to its advanced LN2 blast freezing design. Where compressors and refrigerants often slow you down, the B-90’s efficient engineering delivers:
- Zero Exposure to Liquid Nitrogen for product or personnel.
- Consistent Cooling: Enjoy ±3°C uniformity across the entire payload bay. Your samples, bags, or vials receive the same reliable freeze every time.
- Shorter Downtime: After opening the door, the chamber returns to -80°C or -90°C in about one minute, so you keep your cycles consistent and quick.


If your facility handles large volumes of temperature-sensitive materials—be it blood, plasma, biologics, vaccines, or other critical lab products—the B-90 gives you the power to freeze them at unprecedented speeds, helping optimize your daily workflow and prevent bottlenecks.
Built-In Thawing, No Extra Equipment Needed
The Cryometrix B-90 doesn’t just blast freeze. It also thaws within the same chamber. Take advantage of temperatures up to +40°C to gently warm your stored materials without needing a separate thawing apparatus. Simply adjust the setpoint on the B-90’s intuitive touchscreen and let it do the rest. No more juggling multiple machines or occupying extra floor space just for thaw cycles.

Real-World Validation in Blood Banking

A major American blood bank replaced two large mechanical freezers (plus a rooftop compressor) with a single B-90—and saw an eightfold increase in throughput. By freeing up floor space and eliminating maintenance headaches, the bank kept more units in continuous processing. The B-90:
- Shortened freeze times
- Reduced the downtime traditionally needed to defrost or repair compressors
- Created a quieter, more efficient work environment
This success story demonstrates the dramatic improvements possible when you switch from outdated mechanical systems to the Cryometrix B-90.
Zero Compressors Means Minimal Maintenance
Mechanical freezers rely on compressors, condenser coils, refrigerants, and oil, all of which wear out or fail over time. This design complexity can lead to:
- Unscheduled Downtime
- Expensive Service Calls
- Larger Maintenance Staff Budgets
The Cryometrix B-90 changes the game with an LN2-based cooling system that has very few moving parts. There’s no compressor to worry about, no refrigerant lines to leak, and no complicated recharges. By doing away with compressor systems entirely, you’ll see far fewer breakdowns, lower repair bills, and significantly less operational hassle. Additionally, LN2 is contained within a sealed system, so there’s never direct contact with your samples or your staff.

Say Goodbye to Overheating and High Energy Bills
If you’ve ever stood near a large mechanical ultra low freezer, you know they can throw off substantial heat into the environment. This in turn taxes your HVAC system, drives up energy costs, and makes it harder to expand your lab operations. The B-90 tackles these issues head- on by using pressurized liquid nitrogen instead of compressor-generated cooling:

Lower Power Draw
No hefty compressors running around the clock. The B-90 mainly uses electricity for fans, sensors, and the control system.

Less Ambient Heat
LN2-based cooling does not pump heat into the room, making it easier to maintain comfortable, stable conditions for staff and equipment.

Reduced HVAC Load
Decrease your reliance on heavy-duty air conditioning to offset the heat from compressors, potentially saving on utility bills and future HVAC upgrades.

Scalable Expansion
If you need more capacity, simply add another B-90 without fear of straining your electrical infrastructure. The self-contained LN2 system keeps electrical requirements surprisingly modest.
Data Logging and Security Features
Maintaining a strict chain of temperature control is vital in laboratories that handle precious or regulated materials. The B-90 was designed with state-of-the-art data logging and security capabilities:
- Touchscreen Interface: Instantly view current temperature, setpoints, logs, alarms, and user permissions.
- Exportable Logs: Download CSV files to your computer or network, making it easy to archive or review temperature data and user actions.
- User Management: Create up to 30 users across three standard security levels to control who can adjust settings or open the door. For labs needing expanded access management, an Industrial PC (IPC) upgrade offers even more user levels.
- Optional IPC upgrade: Upgrade the control package if you operate under FDA-regulated conditions requiring validated electronic records and signatures.
These built-in tools save time, boost accountability, and simplify audits—especially in cGMP environments.
A 20-Year Warranty on the LN2 Cooling System
A strong warranty says a lot about quality and confidence. Cryometrix backs the B-90’s cooling system with a 20-year warranty on parts, reflecting how robust and dependable this LN2 design truly is. Compare that with the shorter warranties typically offered on mechanical freezers, and you’ll quickly see how the B-90 stands apart. With so few mechanical components, failures are inherently less common. But if something does happen to the LN2 cooling system, rest assured you’re covered.
