Eliminate uncertainty in your freeze-thaw processes. Purpose-built for bio-processing applications, the Controlled Rate Chamber Model 4000 offers uniformity and repeatability in rapid, controlled freezing and thawing applications. The forced air convection cooling rapidly freezes material from ambient to –80 °C.



  • Rapid pulldown - Pull down an empty chamber from –80 to +25 °C in less than 38 minutes

  • Excellent product uniformity - One complete air exchange per second (1000 CFM), product temperature uniformity of ±1 °C, and air temperature uniformity of ±2 °C
  • Universal container acceptance - Precisely freezes small or large volumes of product in nearly any container type or size
  • Customizable freezing and thawing - Programmable freeze /thaw profiles match your process (–80 to +25 °C setpoints)
  • Integrated process documentation - Optional product probe monitors freeze/thaw process for data documentation
  • Proven track record - Adopted by 30 of the world’s largest pharmaceutical companies


Forced Air Convection: An Industry Game Changer -FARRAR pioneered forced air convection technology in its reach-in chambers. This key differentiator affects uniformity. The chambers uniformly force air at the targeted temperature throughout the chamber. Consequently FARRAR freezer and freeze/thaw equipment is up to 10 times more efficient at removing heat than the traditional cold-wall heat displacement process.
