Environmental Control and Monitoring Products for Sealed Containers

Protection Against Pressure, Moisture, Corrosion, and Impact

AGM Container Controls manufactures environmental control, monitoring, and container-access products designed to protect sealed enclosures, containers, and sensitive equipment during storage and transport. More than “off the shelf,” AGM engineers work with you to ensure the solution fits your application. Products are proudly made in the USA at our ISO 9001 / AS9100-certified manufacturing facility.

Pressure Control

Flow more air faster and stop pressure or vacuum differentials before they cause damage with AGM breather valves, filtered vents, and immersion-proof breathers.

Moisture Control

Get greater moisture adsorption in the size or shape you need to stop moisture and humidity from damaging your equipment with AGM desiccants, desiccators, and oxygen absorbers.
humidity indicator cards and plugs

Humidity Monitoring

Know the humidity level of your sealed spaces better, faster, and at scale with AGM humidity indicator cards, plugs, and electronic humidity indicators.

Moisture Purging

Get a better, more thorough moisture purge of your hygroscopic materials compared to traditional dual-point systems. Use AGM single point and through-purge NEPS dry gas purging systems when you flow through and pressurize your sealed spaces and closed containers.

Container Access

Want to see inside or store documentation in a sealed container without having to open it and introduce moisture and other contaminants? Now you can! Prevent unnecessary moisture and contaminant ingress into your sealed container with AGM access ports, observation windows, and records holders.

Shelving & Straps

Military grade shelving and straps for securing & protecting equipment during transport or storage. Custom solutions available.
Lansmont Saver Shock Recorder

Shock Monitoring

Our tamper proof and reusable shock monitors have aided the design of equipment, cases, and even resolved disputes between carriers and suppliers. Record and analyze shock and impact experienced by your equipment during storage or transport with AGM Shockmaster shock indicators and Saver vibration recorders.

Corrosion Prevention

Preserving materials under the harshest conditions, AGM VpCI products have been trusted by the military and industrial suppliers for decades. Stop moisture and oxygen from corroding your electronics and metals with AGM vapor phase corrosion inhibiting paints, primers, coatings, kraft paper, boiler lizards, and gusset bags.

Product Families Overview

AGM products are organized into eight primary categories, each addressing a specific environmental or handling risk inside sealed containers.

Pressure Control

Regulate internal pressure and vacuum conditions to help prevent deformation, seal stress, and pressure-driven moisture ingress during storage, transport, and environmental changes.
Explore Pressure Control

Moisture Control

Manage internal humidity to reduce corrosion, condensation, and moisture-related degradation using desiccants, desiccators, and oxygen absorbers for sealed spaces and containers.
Explore Moisture Control

Humidity Monitoring

Measure and verify humidity levels inside sealed spaces using humidity indicator cards, plugs, sensors, and electronic indicators—supporting inspection and quality processes.
Explore Humidity Monitoring

Moisture Purging

Purge moisture from sealed spaces using dry gas purging systems (single-point and through-purge configurations) to support controlled internal conditions for sensitive materials and long-term storage.

Corrosion Prevention

Reduce oxidation and corrosion risk during storage and transport using vapor phase corrosion inhibitors (VpCI) and related corrosion protection materials for demanding environments.
Explore Corrosion Prevention

Shock Monitoring

Detect and document shock and impact events during handling and transport using shock indicators and recorders—supporting inspection decisions, accountability, and quality documentation.
Explore Shock Monitoring

Container Access

Add access points, observation windows, and record holders so you can view contents or store documentation without opening the container and introducing moisture or contaminants.

Not Sure Where to Start?

Choosing the right product category depends on enclosure size, storage duration, environmental exposure, and equipment sensitivity.

  • Managing humidity and condensation risk? You need Moisture Control

  • Verifying internal humidity conditions? You need Humidity Monitoring

  • Addressing pressure changes during transport or storage? You need Pressure Control

  • Purging moisture from sealed spaces? You need Moisture Purging

  • Preserving metal surfaces during storage? You need Corrosion Prevention

  • Documenting impacts and handling events? You need Shock Monitoring

  • Accessing contents or storing docs without opening? You need Container Access

  • Securing equipment in transit/storage? You need Shelving & Straps

AGM can assist you in evaluating application requirements and recommending an approach aligned with your quality, handling, and storage needs.

How AGM solutions work together: Building a Complete Protection Strategy

In many applications, environmental and handling risks overlap. AGM product categories are often used together to support comprehensive protection strategies, for example:

  • Moisture Control and Corrosion Prevention: reduce humidity-driven oxidation risk for metal components during long-term storage

  • Pressure Control and Moisture Control: manage pressure differentials that can stress seals and contribute to moisture ingress

  • Humidity Monitoring and Moisture Control / Purging: verify internal conditions and support inspection or quality requirements

  • Shock Monitoring and Any category: document handling exposure for high-value or compliance-sensitive shipments

  • Container Access: support inspection and documentation needs without breaking container integrity

Product FAQs

AGM manufactures environmental control and monitoring products designed to protect sealed containers and stored equipment. Core product families include moisture control, pressure regulation, corrosion prevention, and shock monitoring solutions.

Yes. There are many storage and transport applications wherein environmental risks overlap. For this reason, moisture control, pressure regulation, corrosion prevention, and shock monitoring products may all be used together depending on application requirements.

Selection depends on the primary environmental or handling risk affecting the enclosure. Factors such as humidity exposure, pressure changes, storage duration, and equipment sensitivity help determine the appropriate solution.
