What is a Walk-In and Drive-In test chamber?

A Walk-In environmental test chamber is an insulated panelized or welded system that can be configured to multiple sizes for storing products in specific environmental conditions and also for product reliability and validation testing. Walk-in test chambers can be designed with foam panels that lock together to create various box sizes or fully welded versions depending on the simulated environment and performance conditions that need to be simulated.

Drive-In test chambers utilized the same types of box construction and are used to test full-size vehicles from motorcycles to automobiles to full-size trucks. Multiple conditions may be simulated in a walk-in or drive-in environmental test chamber depending on the test requirements. These may include temperature, humidity, vibration, altitude, solar, salt spray, and more in order to test products in multiple environments that they may be exposed to during the life of the product.

What temperature and humidity ranges can walk-in/drive-in chambers achieve?

Walk-in and drive-in chambers typically operate from -70°C to +180°C (-94°F to +356°F), or up to +85°C for panelized chambers, with humidity control from 20% to 95% RH. The specific range depends on chamber size, configuration, and application requirements. Weiss Technik chambers utilize advanced refrigeration systems and precise control technology to maintain tight tolerances across the entire testing volume.

What industries use walk-in and drive-in environmental test chambers?

Key industries include aerospace for aircraft component testing, automotive for full vehicle climate testing, defense for military equipment qualification, telecommunications infrastructure testing, pharmaceuticals for stability testing, electronics, and research institutions. Drive-in chambers for full vehicle testing are particularly valuable for automotive and defense industries.

What environmental conditions can walk-in and drive-in test chambers simulate?

Walk-in and drive-in environmental test chambers simulate comprehensive real-world conditions including extreme temperatures, humidity levels, and combined environmental stress testing with simultaneous temperature/humidity cycling, thermal shock, solar radiation simulation, vibration integration, altitude simulation, and specialized atmospheric conditions. These systems also integrate with other systems such as vibration shakers and dynamometers.
