ACS Thermal Shock Chambers

ACS thermal shock chambers stand out for their utmost flexibility. Available in several versions to better suit different testing needs.

ACS Thermal Shock chambers are designed for air-to-air or liquid-to-liquid thermal shock tests, to test components or equipment automatically, submitting them to rapid temperature changes. They are suitable for Quality Control Laboratories or in Production plants for the screening of the commercial and military components.

Key Features of ACS Thermal Shock Systems:

• Use of ecological refrigerants such as R404a, R23.
• Basket transfer time from one compartment to another less than 10 seconds.
• Fast recovery and stabilization times during hot-cold and cold-hot transfers, thanks to low thermal inertia and to the absence of radiating heat inside the chamber.
• High response speed and linearity in the -100° C/+200° C range, thanks to a powerful thermoregulation system.
• Doors equipped with a special automatic system blocking the running test at door opening.
• Recirculation system ensuring a perfect air distribution inside the chamber.
• Low liquid consumption on CSTL models (0.5 g/h for CSTL20).
• Use of one liquid only (CSTL30).

Air-to-Air Thermal Shock Systems meet or exceed the following standards:

• MIL-STD 202 D/E/F, method 107C/F/G, test conditions A, B, C, F
• MIL-STD 202 D/E, method 102 A

Liquid-to-Liquid Thermal Shock Systems meet or exceed the following standards:

• MIL-STD 202 F, method 107G, test conditions AA, BB, CC, DD
• MIL-STD 883 A, method 1011.1, test conditions A, B, C, D (on request E/ F)
• MIL-STD 883 C, method 1011.4, test conditions A, B, C, D(on request E/ F)
• MIL-STD 883 C, method 1011.7, test conditions A, B, C, D (on request E/ F)
• MIL-STD 883 C, method 1011.9, test conditions A, B, C
• MIL-STD 883 D, method 1011.9, test conditions A, B, C . IEC 68-2-14 (test Nc, severity 1)

The extreme versatility of ACS chambers allows users to carry out a wide range of tests necessary to determine thermal characteristics under the effect of two alternating extreme temperatures. It is possible to offer standard or custom-designed models, either vertical, horizontal or "walk-in" types. Their wide range of accessories, the large range of temperatures, the reliability of the mechanical cooling systems and the After-Sales Service Assistance contribute to make ACS chambers an essential factor for Quality Control and Production facilities.
