Purpose-built for life science applications.
FARRAR® pioneered forced air convection cooling to answer the challenge of preserving and storing biological and tissue donor samples and materials.
Our Ultra-Low Chamber (ULC) Series are the only +2°C to +8°C and -20°C to -80°C (with options for -40°C storage) forced air, ultra-low temperature freezers on the market.


Chamber Volume: 190 cu. ft. (5,380 L)
Area Footprint: 47 sq. ft. (4.36 m2)
Material Handling: Shelves, Product/Transfer Carts

Chamber Volume: 259 cu. ft. (7,334 L)
Area Footprint: 73.2 sq. ft. (6.8 m2)
Material Handling: Sliding Shelves, Product/Transfer Carts

Chamber Volume: 328 cu. ft. (9,288 L)
Area Footprint: 73.2 sq. ft. (6.8 m2)
Material Handling: Pallets, Product/Transfer Carts
Optimized Footprint
Up to 50% less floorspace vs. standard ULT configurations with up to 8x the capacity depending on the ULC size (one ULC = six ULTs)
Industry’s Fastest Temperature Recovery
Up to 10x faster temperature recovery from door opening helps ensure product integrity
Tight Temperature Uniformity at Any Set Point
No matter the set point, count on better than +/- 3°C even during a defrost cycle
Integrated, Fully Redundant System
Eliminates need for backup freezer or liquid nitrogen system
FARRAR’s Ultra-Low Chamber (ULC) Series freezers can be configured for product/transfer carts, racks, sliding shelves, and pallet storage to provide secure, flexible, efficient, and redundant storage for any cold storage project.




Forced air convection technology affects two critical performance metrics: uniformity and chamber pull down/recovery.
ULC Series freezers uniformly force air at the targeted temperature throughout the chamber. The result? FARRAR freezer and freeze/thaw equipment is up to 10 times more efficient at removing heat than the traditional cold-wall heat displacement process.
But we didn’t stop there. Recovery from door opening is critical to helping ensure product integrity. We designed the FARRAR ULC Series with dual refrigeration units, which allow the chambers to recover back to -80°C at a rate that is three times faster than a conventional cold wall freezer.
