The technicians at Shanghai Jianhu Instrument Equipment Co., Ltd. conducted an experiment to evaluate the performance of insulation materials used in constant humidity and temperature test chambers. They found that high-quality insulation materials do not feel hot to the touch, with a cool exterior that poses no risk to human safety. In contrast, lower-quality materials can become extremely hot, making them unsafe and potentially harmful.
High and low temperature test chambers are essential for temperature-controlled testing and require effective insulation. The selection of insulation material thickness and type plays a critical role in the overall performance of the equipment. Today, we’ll explore how to choose the right insulation material for these devices.
As more manufacturers produce constant temperature and humidity test chambers, quality issues have also become more common. Insulation materials are a crucial component in these devices. High-quality insulation is placed between the outer casing and inner liner, directly impacting the cabinet’s thermal performance. If substandard materials are used, it can lead to poor temperature uniformity, reduced durability, and even cause the outer shell to become dangerously hot, posing a risk to users.
Proper insulation in industrial equipment and piping systems helps reduce energy consumption, lower costs, and improve environmental conditions, offering significant economic benefits. For external wall insulation, the material must withstand various environmental stresses such as water exposure, freezing and thawing cycles, weather changes, impact, and strong winds.
When selecting insulation methods, the heat transfer mechanism is considered, along with the appropriate materials and techniques. For instance, to prevent heat loss from hot air, a vacuum insulation layer may be used. However, due to technical and cost limitations, most environmental test equipment today uses traditional insulation materials like glass wool, polyurethane foam, polystyrene foam, and similar options.
Choosing the right insulation is not just about performance—it’s also about safety, efficiency, and long-term reliability. Whether you're designing a new test chamber or upgrading an existing one, paying attention to the insulation material can make a big difference in both functionality and user experience.
