Cryometrix Blast Freezers

Cryometrix offers a complete portfolio of LN2 blast freezers and blast plate freezers engineered for ultra-fast freezing, precise temperature control, and scalable performance in life science, biopharmaceutical, and research environments.

Unlike traditional compressor-based systems, Cryometrix freezers use liquid nitrogen (LN2)- cooled air in a contained system, enabling faster pull-down speeds, improved temperature uniformity, and reduced maintenance. This approach supports high-throughput workflows while minimizing downtime and operational complexity.

From compact lab-scale units to production-scale systems and hybrid technologies, Cryometrix provides solutions optimized for blast freezing, thawing, and advanced plate freezing applications.

Cryometrix MB-90 Blast\Thaw Freezer

Cryometrix MB-90 Blast/Thaw Freezer

The Cryometrix MB-90 blast freezer is a compact, high-performance solution designed for laboratories, process development, and smaller-scale bioprocessing environments.

Despite its size, the MB-90 delivers industry-leading performance, achieving ambient-to -90°C in as little as 3 minutes. This rapid freezing capability helps reduce ice crystal formation and preserve sensitive materials such as cell therapies, viral vectors, and biologics.


Features and benefits:

  • 3-minute ultra-fast pull-down and approximately 1-minute recovery
  • Compact footprint (under 8 square feet) for space-constrained labs
  • Up to 90% lower energy consumption compared with mechanical freezers
  • Flexible temperature range from +40°C to -90°C
  • Low-maintenance LN2 cooling system with no compressors

The MB-90 is well suited for R&D, clinical workflows, and scale-down modeling. It shares core technology with the B-90, allowing processes developed at lab scale to transfer efficiently into production environments.

Choosing the Right Cryometrix Freezer

Cryometrix systems are designed to support different operational needs:

B-90

for high-capacity, production-scale blast freezing

MB-90

for compact, fast-cycle lab
and development work

PF-90

for combined blast and plate freezing where precision and flexibility are required

Together, these solutions help optimize freezing performance, improve product quality, and support efficient workflows across research, clinical, and manufacturing environments.

Understanding Blast Freezing

Blast freezing is a rapid-freezing method that uses very cold, high-velocity airflow to remove heat quickly, uniformly, and consistently from products. Compared with still-air cooling or standard cold storage, blast freezing shortens freeze times, improves repeatability, and helps reduce workflow bottlenecks. It is especially valuable in life science, bioprocess, and pharmaceutical drug production environments where freezing is a critical step before storage, shipment, or downstream manufacturing.

Cryometrix provides liquid nitrogen (LN2) blast freezers that use LN2-cooled air in a contained system designed to avoid LN2 contact with the product or operator. This approach supports rapid cooling, strong temperature uniformity, and efficient operation in demanding environments.

How Blast Freezing Works

Blast freezing increases heat transfer using two key principles:

  • Very low-temperature air to create a strong temperature difference between the product and its environment
  • High airflow to increase convective heat transfer and remove heat more efficiently

Cold air circulates at high velocity around the payload, stripping away the warm boundary layer that naturally forms around containers during freezing. This allows products to reach target temperatures faster and more uniformly than with still-air methods.

Blast freezing is especially valuable in operations with variable loads, different container formats, and frequent door openings, where process consistency and throughput are priorities.

Why Blast Freezing Is Used in Life Science Workflows

Faster Cycle Times

Slow freezing can create delays throughout a facility. Blast freezing helps reduce time-to-freeze, increase throughput, and minimize time spent in transitional temperature ranges.

Better Consistency Across Loads

Controlled airflow and stable chamber conditions help reduce variability between runs, supporting repeatable processes and easier SOP adherence.

Support for Common Container Formats

Blast freezing is commonly used for bags, bottles, and mixed container types because airflow-based systems can accommodate a wide range of payloads.

Reduced Risk of Process Bottlenecks

Freezing is often a hidden production constraint. Faster freezing helps keep upstream and downstream operations moving more efficiently.

Rapid Freezing in Shipping Logistics

Rapid thermal pull-down helps preserve product integrity and validated temperature conditions during storage and transport, which is especially important for pharmaceuticals and biologics.

Mechanical vs. Liquid Nitrogen Blast Freezing

Mechanical blast freezers rely on compressor-based refrigeration systems. While widely used, they can experience slower pull-down and recovery times, especially during heavy use, frequent door openings, or ultra-low temperature operation.

LN2 blast freezing uses liquid nitrogen as the cooling source, enabling faster heat removal and more stable ultra-low temperature performance.

Advantages Of LN2 Blast Freezing

  • Faster Pull-Down to Ultra-Low Targets
    LN2-based cooling can reach ultra-low temperatures much faster than typical mechanical refrigeration. Faster pull-down can reduce overall cycle time, increase daily throughput, and help keep time-sensitive materials moving through a process without long waits.
  • Faster Recovery and Steadier Performance
    In busy environments, door openings and frequent loading can disrupt cycles. LN2 cooling supports faster recovery, helping maintain stable performance under continuous demand.
  • Reduced Dependence on Compressors and Refrigerants
    LN2 blast freezing eliminates reliance on compressor-driven refrigeration components, reducing maintenance complexity and simplifying long-term service planning.
  • Contained LN2 Use for Safer Operation
    Contained LN2 designs use liquid nitrogen as a cooling source while aiming to avoid LN2 contact with the product and operator. This helps deliver cryogenic performance while supporting safer operation.
  • Strong Performance in Compact Footprints
    LN2 approaches can deliver high freezing intensity and ultra-low temperature performance even in compact footprints, making them well suited for space-constrained environments.

Common Blast Freezing Applications

Blast freezing is used across a wide range of workflows where temperature control, throughput, and consistency matter.
