Walk-in environmental chamber
Our walk-in environmental test chambers are your solution for your most demanding temperature and humidity testing requirements. Available in walk-in, drive-in, or environmental room designs, the W-Series offers maximum flexibility in both chamber size and performance.
The welded, one-piece construction of the walk-in chambers allows for rapid thermal change rates, ultra-low temperature cooling, and prolonged soaks at extreme temperatures. Our modular construction WM-Series chambers provide flexibility and can also be manufactured as a dynamometer room or environmental room for long-term stability, accelerated testing, humidity, and forced long-term stability testing.
Walk-in test chambers can be configured for temperature, temperature-humidity, or altitude testing, depending on your specific needs.
