Industrial
Cryogenic Test Chamber
The DHT® Cryogenic Test Chamber is a specialized environmental
simulation system developed by DHT® Test Equipment for low-temperature
light-sensitive testing scenarios. Designed to support extreme cryogenic
conditions, the chamber achieves stable temperature control down to
-100°C, making it ideal for evaluating the thermal and optical
performance of sensors, infrared devices, aerospace optics, and night
vision systems under total blackout conditions. The chamber features a
light-tight, matte-black interior and precision-grade thermal insulation
to prevent both thermal leakage and optical interference. Its advanced
dual-stage cascade refrigeration system ensures uniform temperature
distribution across the workspace, while the DHSPLCON intelligent
control platform enables programmable temperature profiles,
long-duration soak testing, and real-time data logging. With a
corrosion-resistant 304 stainless steel structure and low-emissivity
interior finish, the chamber minimizes reflective interference and
supports high-accuracy dark condition experiments.
Benefits
Precise Simulation of Extreme Cold-Dark Environments: The chamber can precisely simulate cold-dark environments ranging from standard temperatures to as low as -60°C. By controlling temperature, humidity, and light conditions, it closely replicates product performance in real-world space environments.
Efficient Temperature Control System: Capable of rapidly cooling and maintaining a stable low-temperature environment, ensuring precise temperature control throughout the test and ensuring reliable test data.
Light Simulation and Isolation Design: Features a fully isolated dark environment that simulates conditions without sunlight radiation, effectively replicating cold-dark conditions.
High-Efficiency, Energy-Saving System: The device operates efficiently with low power consumption, reducing operational costs and minimizing environmental impact, in line with green and eco-friendly standards.
Comprehensive Safety Protection Mechanism: Equipped with multiple protection systems, including over-temperature, over-pressure, and overload safeguards, the chamber ensures that any abnormal conditions during testing are detected and addressed promptly, ensuring the safety of both the equipment and the test samples.
