Freeze/Thaw
 
  
 
 
Caron’s Freeze/Thaw Chambers precisely control a wide range of temperature and (optional) humidity settings. This broad range encompasses nearly every ambient environment on earth. Automatic, versatile and programmable cycling between setpoints enables continuous simulation of the harsh conditions of freezing and thawing for rapid testing. These demanding temperature and humidity cycling studies require accurate control of thermal conditions, and are best served by our chambers.

Our chambers will accomodate a wide range of freeze/thaw studies, including pharmaceutical drug studies, concrete and asphalt testing, coating and adhesive testing, outdoor weathering tests, stress testing and more! Our product offering includes two sizes of large capacity, reach-in units. Our products are not only consistently reliable, but offer best in class customer friendly features and unique energy efficient components.

Features & Benefits
  • The wide temperature range of -25°C to 70°C and optional humidity range from 20% to 98% offers the flexibility to simulate a broad range of environmental conditions.
  • Deluxe controller includes ramp and soak to cycle freezing and thawing for repeatable, accurate studies. Our controller can perform 4 programs, 40 individual steps, an infinite number of loops and a ramp based on any time or rate.
  • Caron offers an optional factory calibration of the controller and will program it to your specific profile, which makes installation and start up easy.
  • gROD™, Refrigeration on Demand, efficiently manages power consumption and saves electricity.
  • Caron’s humidified Freeze/Thaw Chambers, Models 6220 and 6240, feature gVapor™, which delivers controlled humidity vapor on an as needed basis without wasting energy or producing heat.
  • The deluxe controller comes standard with analog outputs and RS-485 communications and connects the unit directly to an in-house monitoring system.
  • The glass doors are heated, triple-pane and argon filled, which minimizes condensation for a clear view of your samples inside.
  • Caron’s carefully designed horizontal airflow system generates gentle and evenly distributed airflow across all shelf locations. Temperature uniformity and rapid recovery are always maintained, even under heavy loads,]
  • These chambers are designed with high R, CFC-free foam insulation, making them energy efficient.
  • In the event of a power failure, non-volatile memory allows the chamber to return to its original setpoint when power is restored.
  • Setpoint deviation alarm visually and audibly alerts you of a problem with the convenient option to silence the audible alarm.
  • Dual display of temperature and humidity allows you to visualize instantaneous setpoint and operating conditions. Setpoints are easily adjusted by simply pressing the up or down arrow keys.
  • The stainless steel shelves are adjustable and perforated, making them easy to clean and highly resistant to corrosion. These shelves also slide, so whether testing samples or heavy equipment, it is easy to locate all product inside.
  • The interior is comprised of corrosion-resistant stainless steel and is quickly removed without tools, allowing you to reconfigure the interior.
  • Our ergonomic, limolicious door handle is an attractive, modern design, and allows you to easily access the inside of your chamber.
  • Two access ports make validation easy and provide you with convenient access to connect wires and instrumentation.
  • A wide range of accessories are available, allowing you to modify the chamber to your specific application requirements.
