Cascade Cooling System – ThermoScientific


Thermo Scientific™ Forma™ FDE Series ultra-low temperature freezers feature reduced energy usage, a simplified touchscreen interface, four capacities, and an ergonomic cabinet design. Part of the Standard Performance (STP) family and powered by H-drive, maximizing storage capacity from 30,000 up to 60,000 2 mL vials. The FDE series is a sustainable and reliable solution with ultimate sample security and operational savings for every lab.


  • Powered by H-drive’s hydrocarbon technology, these systems save up to  25%  in energy usage and heat rejection over conventional refrigerant ultra-low freezers1
  • Designed for daily usage, recovers cabinet temperature 20% faster after opening the door.
  • A quiet sound output below 53 dBA, enables the freezer to come out of the hallway and into the lab
  • Meets +/-10°C validation protocols at -80°C with strong peak variation and steady-state temperature variation
  • Natural hydrocarbon refrigerants reduce system operating stresses promoting outstanding reliability and worry-free sample protection

User Friendly

  • The H-drive Information Center (HIC) combines easy to read temperature with simple capacitive touch buttons in a 5.6” display
  • Four capacities (300, 400, 500 and 600 2-inch box) to accommodate a variety of storage needs and lab footprint specifications
  • All models contain four inner doors allowing for easy sample access without exposing greater freezer content to ambient conditions
  • Improved customer convenience with new ergonomically designed handle, high contrast eye-level display, and comfortable easy-access shelf locations.
  • Compatible with most racking systems including a full range of Thermo Scientific™ racks for boxes, microplates, Thermo Scientific™ Matrix™ and Nunc CryoBank™ tubes
  • Security features including alarm settings and padlock-compatible doors


  • Manufactured in an award-winning, zero-waste to landfill facility
  • Lower HVAC costs as a result of less heat emission into the environment
  • Natural refrigerants and water-blown foam insulation, making the Series compliant with the U.S. Environmental Protection Agency’s Significant New Alternatives Policy (SNAP), the European Union’s F-Gas and other sustainability standards
