Sigma Hot Cold Temperature Chambers

Sigma Temperature Chambers are precisely temperature controllable convection ovens in which items can be placed for heating or cooling. Also known more generically as “environmental chambers”, temperature chambers are the perfect choice for testing or conditioning large or irregularly shaped items. Temperature chambers are also ideal any time a very homogeneous (low gradient) thermal environment is required.

When compared to thermal platforms, temperature chambers offer the following advantages:

• Homogeneous, low gradient, environment
• Large capacity
• Greater flexibility
• Less fixturing and holding of DUT
• Wide temperature ranges available

Sigma temperature chambers are available as “benchtop” or “floor standing” models. Many of the smaller sizes can also be configured for rack-mounting. The photos on the following pages show both standard and many specially designed and configured custom temperature chambers.
Temperature chambers are heated with electric resistance heaters, have from 1 to 6 blowers for air circulation, and use either cryogenic cooling, refrigeration cooling, or both.

What Temperatures Are Available?
Cryogenic Cooling or Refrigeration Cooling.

The normal upper temperature limit of Sigma temperature chambers is 200°C. All refrigeration cooled chambers are limited to a high temperature of 300°C to prevent degradation of the refrigerant. Cryogenic chambers can have limits of 300°, 350°, 400°, or even 500°C. Temperatures higher than 200°C are extra cost options and each involves considerations you should discuss with your Sigma representative or sales engineer.

The normal lower design limit for Sigma temperature chambers is –100°C. The type of cooling you select will determine how cold your chamber will go.
