Applications
PERFORMANCE, CYCLING WALK-IN TEST CHAMBERS
Performance test chambers are used for iterative testing where conditions fluctuate.
Chambers are available in more than two dozen sizes and can be combined with many power packages. Below is a small sampling of our most common chamber sizes with associated power packages to help you understand the performance options available to you. The matrix allows you to choose by size or by performance needs.


*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.
*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
APPLICATIONS & USE CASES
The WR Walk-In Series is highly customizable, depending on the product you are testing. Engineered as large-scale environmental rooms for full-size assemblies, server racks, satellites, and production-scale payloads, the WR Series is offered as both stability walk-ins (steady-state, long-duration conditioning) and performance walk-ins (iterative thermal cycling). Dimensions, door configurations, live-load capacity, floor loading, temperature and humidity ranges, ramp rates, pass-through ports, and controls are all tailored to the application.
