WHAT ARE DESICCANTS? Desiccants are hygroscopic materials that adsorb moisture from the air. They are often placed in packets made of kraft paper bags, Tyvek®, or custom-shaped and sewn bags. However, desiccants are also used in more advanced devices, such as in desiccators and breathing desiccators to dry an air or gas stream. Most manufactured […]

Calculating how much desiccant you need is really tricky. To get started, use AGM's guide for quickly estimating desiccant amounts.

Moisture control is a critical factor in preserving the quality and longevity of various products. Whether it's electronic devices, foods, pharmaceuticals, or sensitive materials like artwork and optics assemblies, excess moisture can lead to damage and deterioration. That's where indicating silica gel comes into play. What is Silica Gel Desiccant? Silica gel is a desiccant […]

The Aspera Project: Mapping Intergalactic Medium Part of NASA’s Pioneers Program, Aspera is a mission to provide greater understanding of galaxy evolution through observations of the warm-hot gas (intergalactic medium) found between galaxies. The mission will see the development and launch of a SmallSat ultraviolet space telescope. The University of Arizona is the leading institution […]

Ensuring the stability and reliability of rocket propellants is crucial for the success of space missions. However, moisture can compromise these goals, leading to degradation, reduced performance, and safety risks. For these reasons, moisture control plays a vital role in the success off any rocket. Therefore, we will explore the importance and use of desiccants […]

In technical industries like aerospace, it’s rare to find an easy one-size-fits-all solution. As ubiquitous as desiccants are, even standard desiccant solutions are sometimes not enough to adequately deal with the moisture and humidity needs of specialized applications. That’s where customized desiccants fly high. When custom desiccants may be a better option: Volume of Available […]

Choosing the right breather valve to protect your project is no simple task. When it comes to pressure differentials and their interaction with sealed spaces during flight, aerospace engineers must take into account several aspects of pressure and environment to ensure the safety and reliability of their aircraft, spacecraft, and equipment. What are pressure differentials? […]

More than your standard desiccant, activated alumina is known for its ability to effectively dry and purify liquids and gases. What Is Activated Alumina? Activated alumina is a type of desiccant that is commonly used to remove moisture and impurities from gases and liquids. It is made from aluminum oxide (Al2O3), which is heated to […]

Summary Aerial optics systems are under constant development in the aerospace industry and they come with their own set of challenges. For example, the challenge in mitigating the pressure differential on a device housing as it increases and decreases in altitude is often compounded by lens and electronic sensitivities to contaminates, such as moisture and […]
