Walk-in High-Temperature Aging Chamber
Walk-in High-Temperature Aging Chambers are typically assembled on-site using insulated panels (double-sided color steel sheets with insulation material in between). Chamber dimensions are customized to client specifications. The complete walk-in high/low temperature and humidity test chamber features comprehensive safety protection devices and provides troubleshooting methods, with safety ratings surpassing other brands. Protection Devices: Fuse-less switches, fuses, over-temperature protection, dry-run protection, low-water protection, liquid level protection, compressor overpressure, overheat, and overcurrent protection. Comprehensive protection includes compressor overload/overheat protection, phase loss protection, and a fault alarm system.
