Ultra-Low Chamber (ULC) Series
Ideal for high-density material storage across a broad temperature band (+2°C to +8°C and -20°C to -80°C with options for -40°C storage), ULC-328 offers uniform, efficient, sustainable performance to support fully redundant production-scale processing and storage across life science applications.

Forced air convection technology affects three critical performance metrics: temperatureuniformity, chamber pull down, and recovery after door openings.
ULC Series freezers actively circulate conditioned air throughout the chamber. The result? FARRAR freezers and freeze/thaw equipment are over 30% more efficient at removing heat1 than the traditional cold-wall heat displacement process.
But we didn’t stop there. Recovery from door openings is critical to helping maintain product integrity. We designed the FARRAR ULC Series with dual refrigeration units, providing full redundancy and allowing chambers to recover to -80°C up to 3 times faster2 than conventional ultra-low technology.
