Temperature chambers are typically used to test products to ensure that they are reliable and do not fail in the field. There are currently about ten manufacturers of temperature chambers in the United States, some of which have been around for many years.
Most of these manufacturers also manufacture other types of environmental test chambers which could include: Thermal Shock Chambers Temperature Humidity Chambers Salt Spray Chambers Altitude Chambers Space Simulation Chambers Temperature Plates Liquid Nitrogen Cooled Temperature Chambers Liquid Carbon Dioxide Cooled Chambers AGREE Temperature Chambers HALT Test Chambers Industrial Ovens Laboratory Ovens Liquid to Liquid Thermal Shock Chambers

A wide temperature range of -70C to +170C can be achieved by a temperature chamber provided it includes a cascade compressor system (two compressors). A range of -35C to +170C is common for a single stage compressor system.
Another method to cool Temperature Chambers is CO2 or LN2. Normally a temperature range of -70C to +170C can be obtained by using these cooling methods.
Since most temperature chambers will be used for cycling the test product through a range of temperatures, a maximum obtainable temperature ramp rate is normally specified. 2c/min is average for a mechanically cooled chamber (with a maximum specified product load. If you require a faster ramp rate, then CO2 or LN2 boost can be added or larger compressors. Temperature ramp rates of up to 15c per minute are obtainable using LN2 or CO2 and/or large mechanical compressors.
Most temperature chambers today include a programmable temperature controller which allows the user to setup the temperature cycle required. Normally this would involve inputting he up and lower temperature limits of the test and also the number of cycles required. The Watlow F4 Programmable Controller is a good example such a temperature Controller. Many manufacturers of temperature chambers include their own controller. Typical options available for controllers include RS-232 Interface, IEEE-488 and extra event outputs which can be used to control the product being tested.
Other optional items normally available for a temperature chamber are: Window in the Door Feed-Through Ports Castors for easy movement of the chamber Circular temperature chart recorders Dryer package to remove moisture and prevent condensation when chamber is cooled Water or air cooled compressors
