Alternating mould test chamber

The DHT® Alternating Mould Test Chamber is a high-precision environmental testing solution designed to simulate prolonged high-temperature and high-humidity conditions for evaluating mould resistance and fungal growth. It is widely applied in aerospace, electronics, automotive, and advanced material industries, making it ideal for testing scenarios where microbial contamination or material degradation is a concern. This chamber plays a critical role in helping research institutions, testing laboratories, and universities assess the long-term performance and reliability of materials exposed to mould-prone environments.

Engineered for demanding applications, the DHT® alternating mould test chamber is especially suited for evaluating the fungal resistance of electronic components, aerospace composites, automotive interiors, and plastic insulation. It also supports alternating temperature and humidity mould resistance testing for industrial coatings and polymer-based materials. By combining precise temperature and humidity control with reliable test repeatability, the chamber ensures compliance with international standards such as ASTM and ISO.

Constructed with advanced CNC machining and a durable, corrosion-resistant structure, the DHT® mould test chamber delivers both aesthetic quality and long-term operational stability. Whether for basic research or industrial product validation, it provides a consistent and controlled testing environment that meets the rigorous demands of modern environmental simulation. This makes it a trusted choice for any organization seeking to enhance material durability and verify mould resistance under extreme climate conditions.

Benefits

High-Quality Materials: The inner chamber is made from corrosion-resistant SUS304 stainless steel, while the outer chamber uses A3 steel plates with a spray coating, making it visually appealing and resistant to dirt. The materials are durable and long-lasting.

Intelligent Water Supplementation: The water supply tank at the lower right is equipped with an automatic protection system to prevent dry burn damage due to water shortage.

Efficient Insulation: Ultra-fine fiber insulation cotton reduces energy consumption, and the left side features a 50mm test hole for easy external connections.

Powerful Cooling System: The unit uses a French Tecumseh compressor for precise dehumidification, temperature control, and humidity regulation.

Uniform Air Circulation: The multi-wing fan ensures uniform air distribution, with no dead zones in the airflow. The air velocity is ≤0.2m/s, meeting the required standards.

Independent Systems: The heating/cooling and humidification systems operate independently, providing efficient energy use and extending the lifespan of the device.
