4000 Series Controlled Rate Chamber

Reliable, controlled freezing and thawing with forced air circulation for uniform performance.

FARRAR's 4000 Series Controlled Rate Chamber offers uniformity and repeatability in rapid, controlled freezing and thawing applications. Our technology uses forced air circulation to provide efficient pulldown from ambient to the desired temperature. Forced air circulation allows the rapid pulldown process to extend to the fluid core, avoiding false freezing points and optimizing the freezing process (1,000 CFM air circulation).
