PLATE FREEZING

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. 


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.
