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 +25 to −80 °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 (+40 to −80 °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.
