The 4000 Series Controlled Rate Chamberoffers uniformity and repeatability inrapid, 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).

This unique, convection-based, controlled freezing and thawing process eliminates uncertainty and allows temperature-specific conditioning to satisfy processing and shipping protocols for various pharmaceuticals. Our4000 Series Controlled Rate Chamberunits can meet your freeze/thaw application needs from +40°C to -80°C.
