Freeze Thaw Chambers
 
Caron’s Freeze/Thaw Chambers precisely control a wide temperature range of -25°C to 70°C and (optional) humidity range of 20-98% for reliable and repeatable ramp and soak testing.  
 
Programmable environmental conditions encompass nearly every ambient environment on earth. Setting up and managing ramp and soak profiles is easy and intuitive with Caron’s new touchscreen control system. The ramp/soak program includes five profiles with up to 10 steps each (50 total steps). The repeat feature allows multiple and continuous routines so sequences are automatic and versatile for cycling between setpoints.  
 
Common applications for these chambers include: freeze/thaw studies, pharmaceutical drug studies, concrete and asphalt testing, coating and adhesive testing, outdoor weathering tests, stress testing and more! Not only are these Freeze/Thaw Chambers consistently reliable, but they also offer energy efficiency and best-in-class customer friendly features.

 
Features & Benefits
 
  • A temperature range of -25°C to 70°C and humidity range (optional) from 20% to 98% offers the flexibility to simulate a broad range of environmental conditions.  
  • The 7” color touchscreen is intuitive and features easy-to-read icons and a familiar, user-friendly display that can be operated with gloves on.   
  • The user interface includes a configurable status center with built-in information updates, alerts and alarms to communicate a wide range of status conditions.   Ramp and Soak
  • Ramp and soak programming is built into the touchscreen control system, making it easy to setup automatic freezing and thawing cycles for repeatable, accurate studies. Setup an infinite number of loops and a ramp rate based on real-time.  
  • gROD™, Refrigeration on Demand, efficiently manages power consumption and saves electricity.  
  • Humidified models use Caron’s gVapor™, which delivers controlled humidity vapor on an as-needed basis without wasting energy or producing heat.   
  • In the event of a power failure, non-volatile memory allows the chamber to return to its original setpoint when power is restored.    
  • The interior is comprised of stainless steel, which is easy to clean and highly resistant to corrosion.   
  • These chambers are designed with high R, CFC-free foam insulation, making them energy efficient. 
  • Our tool-less removable interior uses stainless steel latches, making it easy to clean and reconfigure.  
  • Caron green door handles are aesthetically pleasing and enhance ergonomics.   
  • The glass doors are heated, triple-pane and Argon- filled, minimizing condensation for a clear view inside.   
  • Caron’s carefully designed horizontal airflow system generates gentle, evenly distributed airflow across shelf locations. Temperature uniformity and rapid recovery are always maintained, even under heavy loads.   
  • The stainless steel shelves slide into place and are adjustable, making them easy to clean and relocate.  
  • Two access ports (one on each side) make validation easy and provide convenient access for instrumentation.   
  • Many optional accessories are available, allowing you to modify the chamber to your specific application.
NEW Touchscreen Control System: Dependable, Reliable and Easy-to-use!
 
Freeze Thaw ChambersThe intuitive control panel has a real-time clock, is easy to reach and simple to use with fewer buttons to navigate. Just touch the 7” full-color screen to put command at your fingertips. Our system controls are “smart,” using breadcrumb trail navigation to keep track of your location within the menus.  The built-in, icon-based status center provides vital information updates, including: alerts, alarms and information statuses, allowing for peace of mind, worry-free operation.
 
All alerts, alarms and information status icons will display in the status bar when initiated, with additional information ready-to-read by simply selecting the icon. An on-screen trend graph displays seven days of operational data with the push of a button.  
 
Our snooze mode is a convenient new function that allows you to be reminded of alarms at a later time. Additionally, the built-in intelligence avoids nuisance alarms and the password protection feature prevents unauthorized access. Alerts warn the operator of an impending problem before it occurs. This gives the user time to react and avoid out-of-spec conditions. Alerts also include messages that provide basic preventative maintenance information, allowing you to service your chamber on a regular basis. By supporting regular service of your Caron chamber, you are enhancing and preserving its reliability.  
 
Information statuses include important updates, such as in-process information for automated programs and standard program cycles/modes. In the event of variant environmental conditions, Alarms visually and audibly alert you of setpoint deviations with the convenient option to silence and/or snooze the alarm.
