CRYOMETRIX PF-90
BLAST PLATE FREEZER

Plate Freezing
Cryometrix plate freezing technology is designed for applications where freezing uniformity, product consistency, and process control are critical. The Cryometrix PF-90 Blast Plate Freezer combines conductive plate freezing with LN2-powered ultra-low temperature performance to support demanding biopharmaceutical, blood banking, plasma processing, and research workflows.
Unlike traditional mechanical plate freezers that rely on compressor-based refrigeration and refrigerant circulation within plates, the PF-90 uses liquid nitrogen cooling to deliver rapid pull-down, consistent ultra-low temperature operation, and simplified maintenance. This approach supports repeatable freezing while reducing system complexity.
For organizations freezing bagged biologics, plasma products, pharmaceutical intermediates, or other temperature-sensitive materials, Cryometrix plate freezing provides a controlled method for removing heat evenly and efficiently.

Cryometrix PF-90 Blast Plate Freezer
The Cryometrix PF-90 is a hybrid blast plate freezer engineered to provide both conductive plate freezing and LN2 blast freezing in one system.
For plate freezing applications, the PF-90 uses direct contact between cold plates and bagged product to remove heat uniformly across the payload surface. This conductive approach is especially valuable for standardized bag formats where consistent freezing profiles are needed to support product quality and process reproducibility.
Features and benefits:
- Conductive plate freezing for consistent heat removal
- LN2-powered cooling for rapid ultra-low temperature performance
- Integrated blast freezing capability for added process flexibility
- No refrigerant circulation within plates, reducing complexity and maintenance
- Improved uniformity for bagged products through direct contact heat transfer
- Reduced ice crystal formation to help preserve product integrity
- Flexible operation for standardized bags and mixed workflows
- Compressor-free design for lower maintenance requirements
- Integrated controls and data logging capabilities


The PF-90 helps facilities consolidate freezing workflows while maintaining precise control over critical freezing conditions.

Advantages of Conductive Plate Freezing

More Uniform Freezing Profiles
Plate freezing removes heat through direct surface contact, helping reduce temperature variation across the product.











Efficient Heat Transfer
Because the product is pressed against cold plates, heat can be removed more efficiently than with still-air freezing methods.











Better Support for Bagged Products
Bagged materials are well suited to plate freezing because their flat geometry allows strong contact with the freezing surface.











Improved Process Repeatability
Standardized plate contact, bag formats, fill volumes, and freezing protocols can help teams create more repeatable processes.











Reduced Product Variability
More consistent freezing conditions may help reduce variability in product quality, especially for sensitive biological materials.


LN2 Plate Freezing vs. Traditional Plate Freezing
Traditional plate freezers commonly rely on mechanical refrigeration systems, compressors, and circulating refrigerants. While these systems are widely used, they can add maintenance complexity and may require more infrastructure to support ultra-low temperature performance.
Cryometrix LN2 plate freezing uses liquid nitrogen as the cooling source, allowing the PF-90 to achieve rapid ultra-low temperature performance without compressor-driven refrigeration or refrigerant circulation within the plates.
Advantages of LN2 Plate Freezing
- Faster pull-down to ultra-low temperatures
- Reduced dependence on compressors
- Lower maintenance complexity
- Reduced heat output into the facility
- Simplified long-term service planning


Plate Freezing Applications
Cryometrix plate freezing is designed for workflows where uniform freezing and product integrity are essential.

















Blood Plasma Freezing
Plate freezing supports consistent freezing of bagged plasma products, helping blood banks and plasma processors improve throughput and repeatability.











Biopharmaceutical Manufacturing
Biologics, buffers, intermediates, and other pharmaceutical materials can benefit from controlled freezing profiles and reliable ultra-low temperature performance.











Cell and Gene Therapy
Temperature-sensitive advanced therapies require careful handling. Plate freezing can support controlled freezing workflows for materials stored in compatible bag formats.











Pharmaceutical Bag Freezing
The PF-90 is well suited for standardized bagged liquids used in pharmaceutical and bioprocessing environments.











Research and Clinical Laboratories
Research teams can use plate freezing to support repeatable experiments, process development, and controlled freeze studies.


When to Use Plate Freezing
Plate freezing is especially useful when products are:
- Stored in bags or flat-format containers
- Sensitive to freezing variability
- Processed in standardized volumes
- Requiring repeatable freezing profiles
- Part of regulated or quality-sensitive workflows
- Better suited to conductive cooling than air-only freezing
For irregular containers, mixed loads, or workflows requiring airflow around multiple package types, blast freezing may be more appropriate. For flat bagged products requiring uniform direct-contact freezing, plate freezing is often the better fit.


Plate Freezing FAQs
What is plate freezing?
Plate freezing is a conductive freezing method that removes heat through direct contact between cold plates and the product.
How do Cryometrix Plate Freezer Differ from other Plate Freezers?
The key distinction is that a conventional plate freezer cools the plates from the inside using circulating refrigerants or cooling fluids, whereas a Cryometrix plate freezer cools the plates from the outside using high-velocity air that has been chilled by liquid nitrogen. This eliminates internal plate refrigeration circuits while still providing efficient conductive heat transfer to the product.
What products are commonly plate frozen?
Plate freezing is commonly used for plasma, biologics, pharmaceutical intermediates, buffers, and bagged liquid products.
Why is plate freezing effective for bagged products?
Bagged products often have flat surfaces that allow strong contact with freezing plates, improving heat transfer and freezing uniformity.
Does the PF-90 only perform plate freezing?
No. The PF-90 combines conductive plate freezing with LN2 blast freezing, giving facilities flexibility to support different freezing workflows in one system.
What are the advantages of LN2 plate freezing?
LN2 plate freezing provides rapid ultra-low temperature performance, reduced compressor dependence, simplified maintenance, and strong freezing uniformity.
