FARRAR 4000 Series Freeze-Thaw Chamber (Controlled Rate Chamber)

Overview

High-performance controlled rate chamber built for bioprocessing. Enables rapid, uniform freezing and thawing from +40°C to −80°C in hours rather than days, with precise temperature control and programmable profiles.

 

 

 

Product Details

  • Purpose-designed for bulk freezing and thawing of biologic products (e.g., proteins, bulk solutions, single-use bags, bottles, SUS, polycarbonate or polypropylene containers).
  • Forced-air convection refrigeration provides fast, uniform cooling.
  • Available as 4002/05 (air-cooled) or 4102/05 (water-cooled) variants.
  • Full-range temperature capacity: from +40°C (thawing) to −80°C (freezing).
  • Large 12-inch HMI touchscreen for real-time chamber and product temperature display, profile programming, and six custom freeze-thaw profiles.
  • Programmable with ±1°C product temperature tolerance.
  • Pull down (empty chamber) from +25°C to −80°C in under 38 minutes; for a 100L load, achieves −80°C in under 12 hours.
  • Up to 60 air exchanges per minute (approx. 1,000 CFM) ensures uniform airflow and rapid conditioning.
  • Chamber volume: approximately 23.3cuft (660L).
  • Uniformity: air ±2°C; product ±1°C.
  • Ambient operating range: +18°C to +30°C.
  • Auto-defrost system; door-open recovery to setpoint in less than 10 minutes.
  • CE and UL-field listing certifications; IQ/OQ/PQ validation support is available.
  • Supports a wide range of container types with customisable shelf layouts.

 

 

  • Bioprocessing units for rapid freeze-thaw of proteins, cell cultures and vaccine intermediates
  • Clinical and pharmaceutical manufacturing environments requiring validated, repeatable freeze-thaw cycles
  • Research and development labs processing bulk materials under controlled cooling profiles
