Quanta™ Non-Sterile Production Freeze Dryer

Versatile Industrial Freeze Dryer

To accommodate the large range of requirements between each industry, Millrock Technology offers Non-Sterile Freeze Dryers in the following specifications:

  • 304L stainless steel for non-pharmaceutical applications.
  • 316L stainless steel for pharmaceutical applications.

Custom Designed to Fit Your Needs

Our lyophilizers can be custom designed to fit your specific application needs. Our condenser assemblies can be internal or external with the option of either bulk or stoppering style shelf assemblies. Cylindrical chambers are another option that offer cost savings and can be supplied up to 200 square feet in shelf area. Additionally, options such as: isolation valves, redundant compressors, redundant vacuum pumps, and clean-in-place (CIP) piping can also be provided.
